Moreno Posted March 17, 2017 Share Posted March 17, 2017 (edited) Is there some material which does have good electron conductivity and hole conductivity as well, but in the same time electron-hole recombination have to be prevented by some physical effect, for examply by a large band gap between conduction and valence bands? So, it does suppose to have a plenty of electrons in conduction band and plenty of holes in valence band, but a large band gap in betweeen?

Klaynos Posted March 18, 2017 Share Posted March 18, 2017 The best is probably something like InSb but the band gap isn't very great. I'd suggest reading about different types of semiconductor and semimetals. Link to comment Share on other sites More sharing options...

Enthalpy Posted April 2, 2017 Share Posted April 2, 2017 I don't see anything special with the band structure of InSb: http://www.ioffe.ru/SVA/NSM/Semicond/InSb/bandstr.html or did I miss something? Double post alas. See my answer in the other thread. A large band gap does not prevent recombination. Link to comment Share on other sites More sharing options...
Moreno Posted April 4, 2017 Author Share Posted April 4, 2017 If band structure is inverted like in HgTe, can recombination happen in principle? Link to comment Share on other sites More sharing options...
