Abstract
An attempt is made to study theoretically the influence of magnetic quantization on the field emission from quaternary alloys at low temperatures on the basis of three-band Kane model, taking In1-xGax AsyP1-y lattice matched to InP as an example. It is found that the current density due to field emission increases with increasing carrier degeneracy in an oscillatory manner. Besides, the same current density increases with increasing electric field and decreasing alloy composition, respectively. In addition, the corresponding results of parabolic energy bands are also obtained from the expressions derived.
