Abstract
The conductivity of liquid selenium has been measured in the temperature range 200°–500°C. The resistivity was expressed by log10ρ=A+(B/T). Average values for different selenium lots and melts of A and B were −3.81 and 5850. The maximum deviations from the averages were 10 percent and 3.4 percent respectively. The resistivity was a function of temperature alone. Various non‐metal impurities Cl2, I2, P lowered the resistivities and produced different values of B in different temperature ranges. Mercury addition caused no change in either A or B although that metal greatly influences the resistance of solid hexagonal selenium. Melts doped with Cl2 or Br2, along with Hg exhibited behaviors different from those with single additions. It was concluded that selenium is an ideal semiconductor in the range of measurement.This publication has 3 references indexed in Scilit:
