ABSTRACT
Recent decades have witnessed numerous experimental procedures for creating a very sharp spatial
temperature inhomogeneity in various materials. Thus, temperature gradients of up to 10
K/cm can be
established by laser radiation on semiconductors, electron-beam material processing, welding, etc. Large
electron temperature gradients can also be achieved by heating up semiconductor charge carriers with
microwave field
; hence the relevance of investigation into semiconductor properties under large
temperature gradients.
