Specific features of the electrical properties of p-type CdxHg1 - xTe/CdZnT
e heterostructures have been studied at liquid-nitrogen temperatures. The a
dopted theoretical model satisfactorily describes the obtained experimental
data. Errors in determining the concentration and mobility of heavy holes-
arising when contributions to the electrical parameters from electrons and
light holes are disregarded-are evaluated. (C) 2001 MAIK "Nauka/Interperiod
