Vi. Kaidanov et al., SELF-COMPENSATION OF ELECTRICALLY ACTIVE IMPURITIES BY INTRINSIC DEFECTS IN IV-VI SEMICONDUCTORS, Semiconductors, 28(3), 1994, pp. 223-237
The current state of the problem of self-compensation in narrow-gap IV
-VI semiconductors is reviewed. A systematic theory for self-compensat
ion is presented for the cases of compensation by single vacancies, by
charged binary complexes, and by neutral complexes. Experimental resu
lts on self-compensation are analyzed for the cases in which various d
onor and acceptor dopants are added to PbS, PbSe, PbTe, the narrow-gap
solid solutions Pb0.8Sn0.2Te and Pb0.93Sn0.07Se, and films of lead ch
alcogenides.
