Semiconductor-metal kinetic phase transition in nearly magnetic semiconductors exemplified with iron monosilicide

Iron monosilicide is used to study the possibility of the semiconductor-metal kinetic phase trans-formation in nearly magnetic semiconductors. It is shown that the heat released by current flow gives rise to a growth in amplitude of spin fluctuations and the attendant splitting of electronic spectra, which, in turn, brings about gap closure and an avalanche increase in the number of charge carriers.
