[edit] your edit to gallium nitride

I have reverted that edit again, you are disrupting the layout of the page, you use two different citation styles, and there are after the reversion duplicate references. If you want to add information, please use this version as a starting point. Kind regards. --Dirk Beetstra T C 01:28, 7 January 2007 (UTC)

Hi! Thanks for cooperating on this article. It improves greatly at the moment (though the references seem a bit single-sided, still, but that happens with certain subjects, and otherwise that will come in time). I will leave the article for a moment, we get into edit conflicts. Keep up the good work, and again thanks for the cooperation. Happy editing! --Dirk Beetstra T C 14:51, 7 January 2007 (UTC)

[edit] Your edit to Light emitting diode

I have again reverted some edits to light emitting diode, which have appeared a couple of time from different users, and have been reverted by two editors. Let me explain why. Firstly, that part of the information is primarily about gallium nitride, not about the diodes. Secondly, the information is strongly influenced by a POV, almost advertising one specific person. Please reconsider these edits, and keep the story and subject of articles. We have wikilinks to point people to other subjects, and information does not have to be scattered around wikipedia, appearing in every article about a subject. Thank you. --Dirk Beetstra T C 15:01, 15 January 2007 (UTC)


"As is known throughout the world, Blue LEDs have been developed based upon the pioneering technology of Professor Isamu Akasaki of the School of Engineering, Nagoya University (currently, Professor Emeritus of Nagoya University, and a Professor of Meijo University). "
This sentence is 1 sentence of press release by Nichia Corporation [1].
Therefore, it is a mistake that Nichia developed LED for the first time. I think that an encyclopedia should mention the truth
.

Wikipedia does not by definition tell the truth, it tells what can be verified by reliable sources. Publications (peer reviewed!) and patents take precedence over press releases, if you can back up the data with these reliable sources, please do so, change the document, and be sure to add the appropriate references. My edit to that part was to remove all personal data (it did look like an advertisement for people and companies), I think most of such information is superfluous, one can tell that blue leds are based on GaN and add a reference to the original sources (which mention the name of the person or company). A biography of a person (please read wp:notability first!) tells about his achievements. I would suggest as a neutral sentence 'have been developed by personrefs and companyrefs', that takes out the who was first bias in that. Hope this helps. --Dirk Beetstra T C 12:06, 17 January 2007 (UTC)

About first nitride based p-n junction blue-LED, it is mentioned in these manuscripts. [2][3].
You should be able to read "The p-n junction LED using Mg-doped GaN treated with LEEBI as the p-type material showed strong near-band-edge emission due to the hole injection from the p-layer to the n-layer at room temperature. " in abstract. This is the world first nitride based p-n junction UV/blue LED. That means that it is known throughout the world.

[edit] Recent edits

If you do not discuss your recent controversial edits to GaN amd LED they will simply be reverted. --Deglr6328 09:46, 17 January 2007 (UTC)

Do you work for nichia? Because that is the only possible way I could see someone taking such a statement a face value. Nichia, being sued by Nakamura at the time, obviously had a vested interest in claiming that he had nothing to do with the invention of the LED. I am not going to allow you to whitewash the led article of all information about Nakamura based on a press release. If you want to state that "Nichia claimes such and such in this press release" ON THE NICHIA PAGE, that's fine. It does not belong on the LED page. Please place all further correspondence on the TALK page of the articles in question. Also see articles Wikipedia:Policies and guidelines and Wikipedia:Sock puppetry. --Deglr6328 18:19, 17 January 2007 (UTC)

I work in the company which is unrelated to Nichia. I work in a semiconductor industry, however there is not an interest with Nichia. I thought that a mistake should have corrected it and wrote in it at Wikipedia.
. Development of nitride based UV/blue light-emitting diodes by Shuji Nakamura is a great mistake and lack in equitableness. The pn-junction nitride based UV/blue light-emitting diode of Nitride was already developed in 1990, when he and Nichia group start a study of the blue LED. About first nitride based p-n junction blue-LED, it is mentioned in these manuscripts　in 1989. [5][6].
You should be able to read "The p-n junction LED using Mg-doped GaN treated with LEEBI as the p-type material showed strong near-band-edge emission due to the hole injection from the p-layer to the n-layer at room temperature. " in abstract of this manuscript. This is the world first nitride based p-n junction UV/blue LED. That means that it is known throughout the world. Moreover, Prof. Nakamura refers to this technology and commercialized LED.

Therefore, I thought that Wilipedia should be carried as follows.

"The pn junction GaN based UV/Blue LEDs were developed by Nagoya University group [4],[5], [6]in 1989, commercialized by Nichia Corporation in 1993 and became widely available by the late 1990s."

With best regards.

[edit] 3RR

Please refrain from undoing other people's edits repeatedly, as you are doing in light emitting diode. If you continue, you may be blocked from editing Wikipedia. Note that the three-revert rule prohibits making more than three reversions in a content dispute within a 24 hour period. Additionally, users who perform a large number of reversions in content disputes may be blocked for edit warring, even if they do not technically violate the three-revert rule. Rather than reverting, discuss disputed changes on the talk page. The revision you want is not going to be implemented by edit warring. Thank you.

Please discuss this on the talkpage. Why do you ignore the recent settlement? --Dirk Beetstra T C 08:03, 18 January 2007 (UTC)

You have presented no convincing evidence of the inventio of the blue led by any other person than nakamura. If you continue to add this bias misinformation to the led article I will initiate a request for comment.--Deglr6328 03:18, 20 January 2007 (UTC)

Why do you say a partial bias misinformation? I write an article based on a perfect evidence. About first nitride based p-n junction UV/blue-LED, it is mentioned in this manuscripts in 1989, which reported by the "Jpn. J. Appl. Phys. Vol. 28 (1989) L2112-L2114" [7]. Moreover, Prof. Nakamura does not begin a study about nitride based blue LED then. Prof. Nakamura should have begun a study in 1990. I want to prepare further evidence if you think it not to be good for evidence.—Preceding unsigned comment added by Miwaya (talk • contribs)

Please conduct further discourse on the talk page OF THE ARTICLE in question instead of here.--Deglr6328 07:47, 20 January 2007 (UTC)

Getting high crystalline quality of GaN and conductive control in GaN were important technology to realize GaN based UV/blue LED. Prof. Akasaki and his group succeed in realization of high crystalline quality GaN in 1986 which reported by "H. Amano, N. Sawaki, I. Akasaki and Y. Toyoda: Appl. Phys. Lett. 48 (1986) 353[AIP]." . Moreover, they realized pn junction and realized GaN based LED in 1989, which report by the "Jpn. J. Appl. Phys. Vol. 28 (1989) L2112-L2114" [8]. You should be able to read "The p-n junction LED using Mg-doped GaN treated with LEEBI as the p-type material showed strong near-band-edge emission due to the hole injection from the p-layer to the n-layer at room temperature. " in abstract of this manuscript [9].
The low temperature buffer layer technology and Mg-doped technology are used approximately entirely with marketed LED now.—Preceding unsigned comment added by Miwaya (talk • contribs)

[edit] Please provide references for the Isamu Akasaki article

I have just added the following note to the talk page of the Isamu Akasaki article, which seems to be mostly your work:

This article seems to contain factual inaccuracies.

  • According to the UC Berkeley website, blue LEDs were first fabricated in 1971 by Jacques Pankove, some 18 years before Akasaki's first success.
  • It also claims that Akasaki began working on blue LEDs in the late 1960s. Is there any evidence to support this claim?
At the moment, this article does not contain a single reference. If nobody can back provide reliable sources to back it up, then it will have to be considered for deletion as original research.

Please let me know what sources you used for this article. -- Sakurambo 桜ん坊 15:03, 23 January 2007 (UTC)
