Properties and stability of parameters of highly compensated PbS-CdS PbS-SnS PbS-PbO and PbTe-CdTe films

摘要

Abstract: The properties of highly compensated quasiuniform films of Pb$-1$MIN@x$/Sn$-x$/S, Pb$-1$MIN@x$/Cd$-x$/S, (PbS)$- 1$MIN@x$/-(PbO)$-x$/, Pb$-1$MIN@x$/Cd$-x$/Te solid solutions with a sodium acceptor impurity are described in this work. The films were grown by the method of molecular beam epitaxy on BaF$-2$/ substrates. It was shown that the films with different composition have the identical electric and photoelectric properties. Temperature dependences of Hall coefficient, dark resistivity and photoconductivity relaxation time have activation character. A high stability of electric and photoelectric parameters after thermal impact and after prolonged storage in the air was obtained. !7
