Effects of the interaction of chlorine with PbTe surface and their effect kinetic parameters of strain-sensitive films

Abstract

In this work, the kinetic phenomena of strain-sensitive thin PbTe films with the presence of chlorine are studied. It has been established that when adding a legirant, the concentration of current carriers and the mobility increase 1.9*1020cm-3, Ϭmax = 4959 ohm-1sm-1, respectively. It has been determined that the coefficient of strain sensitivity of polycrystalline PbTe films doped with chlorine reaches up to 35000 in the strain range (1÷8.5)·10-7 rel.un.
