Abstract

The field emission from III-V, II-VI, PbTe/PbSnTe, strained layer, and HgTe/CdTe superlattices with graded structures under magnetic quantization is investigated and compared with that of the bulk specimens of the constituent materials. The doping and magnetic-field dependences of the magneto-field emission of these superlattices are analyzed, and it is found that the field emission exhibits oscillatory dependences on the inverse magnetic field and electron concentration with more significant oscillations appearing in the HgTe/CdTe superlattices. Relations for the bulk specimens are obtained from the special cases of generalized formulations.
