Recombination Processes in Tellurium

Recombination processes in tellurium have been investigated, chiefly by use of the techniques of photoconductivity. Studies were made on single crystals having acceptor densities of about ${10}^{16}$ per ${\mathrm{cm}}^3$. By using pulsed illumination, the decay time constant of photocurrent was found to be 20 μsec, in fairly good agreement with results obtained previously from steady-state photocurrent sensitivity.
