Electronic properties and pinning of the Fermi level in irradiated II-IV-V2 semiconductors

Experimental data on the electronic properties of II-IV-V-2 semiconductors irradiated with high-energy particles (electrons, protons, and neutrons) are reported. The limiting electrical characteristics of irradiated ternary compounds are evaluated and compared with the corresponding data for the binary III-V analogues of the compounds. Particular emphasis is placed on the determination of the limiting position of the Fermi level, F (lim), in irradiated II-IV-V-2 compounds. The results of calculations of the energy position of the intrinsic charge-neutrality level are presented.
