Title: Superconductivity of thin tellurium films at high pressure

Abstract

A study is presented of the dependence of the temperature of the superconducting transition (T /SUB c/ ) of tellurium films on their thickness and the presence of a dielectric environment consisting of silicon dioxide. The authors measured T /SUB c/ of tellurium films, evaluated at the 50% drop in the resistance, at pressures of 6 GPa, since in this pressure range T /SUB c/ of tellurium is independent of the carrier density in the range 10/sup 14/-10/sup 18/ cm/sup -3/. The experimental results are presented. The tellurium in the 150-nm thick films transformed under a pressure of 4 GPa into the Te /SUB II/ modification and had a transition temperature of T /SUB c/ = 4.2 K.
