Built in voltage[edit]

Should this not be multiplied by e in all the equations, so it has dimensions of energy? (talk) 15:59, 25 March 2011 (UTC)

Nobel Prize[edit]

Probably this is interesting: The 2000 Nobel Prize has been awarded with one half jointly to Zhores I. Alferov A.F. Ioffe Physico-Technical Institute, St. Petersburg, Russia, and Herbert Kroemer University of California at Santa Barbara, California, USA, "for developing semiconductor heterostructures used in high-speed- and opto-electronics" --FrancescoPx 04:26, 8 August 2006 (UTC)

Heterojunction is the wrong place for this[edit]

I am removing this, as it does not apply specificially to heterojunction technology, just GaAs

GaAs has been touted as "the next big technology" to overtake silicon for more than thirty years, but this has not occurred because of the costs. Recent advances in silicon germanium (SiGe) manufacturing technologies might fulfill many of the promises made in the past by gallium arsenide proponents. [citation needed]

None of the references seem to be done properly, i.e. clicking on the [1] in the text should take you to the referrence at the bottom. —Preceding unsigned comment added by Kj cheetham (talkcontribs) 15:27, 26 May 2008 (UTC)

AlAs electron affinity[edit]

are people confident with the AlAs electron affinity quoted here? it's quoted in Adachi "GaAs and related materials" as 3.5 —Preceding unsigned comment added by (talk) 11:02, 8 August 2008 (UTC)

well, i consider it is helpful for meYangjieyzdx (talk) 09:04, 25 November 2015 (UTC)
