Transportation properties of amorphous state InSb and its metastable middle phase

Abstract

The variation of the substrate temperature induces the metal-semiconductor transition in the condensation InSb films at low temperatrue. The electron conduction is dominant in the metal-type amorphous InSb and the hole in semiconductor-type one. In the metal-type amorphous InSb the electron-electron is correlated under the field above 0.1T in the temperature region of liquid nitrogen. The structure relaxation leads to not only the increase of the short range order but also the change of electron structure in metal-type amorphous InSb. The first conductance jump originates mainly from the increase of Hall mobility of the carrier, i.e. the increase of the short range order, and the system relaxes from the liquid-like to the lattice-like amorphous state. The three types of the crystallization phase transition for the metal-type amorphous InSb present obviously different transportation behaviours. Both metal-type amorphous state and metastable middle phase of InSb all are one of superconducting system with the lowest carrier concentration (n{sub 0}{approx}10{sup 18} cm{sup -3}). Superconducting T{sub c} of the metastable middle phase is related to the state density near Fermi surface, i.e. the higher T{sub c} corresponds to the higher state density. The quasi-two-dimensional structure is favourable to superconductivity.
