Talk:Wurtzite

From Wikipedia, the free encyclopedia

Should mention that: due to the wurtzite structure strong built-in electric fields occur, which arise from spontaneous polarisation and if strained, from piezo-electric polarisation. This reduces the efficiency, of e.g. InGaN/GaN or AlGaN/GaN LEDs and lasers. Alternatively it makes these class of material materials suitable candidates for high temperature strain-sensors or ultra-sonic emitters.

And maybe use nanometers instead of picometers for the SI bond-lengths.
