Abstract
AbstractAn attempt is made to study the effect of a quantizing magnetic field on the effective mass in degenerate n‐type ternary semiconductors at low temperatures taking n‐Hg1−xCdxTe as an example. It is found on the basis of the three‐band Kane model, which is the most valid model for n‐Hg1−xCdxTe, that the effective electron mass at the Fermi level shows an oscillatory magnetic field dependence as expected since the origin of the oscillations in the effective mass in small gap semiconductors is the same as that of the Shubnikov‐de Hass oscillations. Besides, the amplitude of oscillations is significantly influenced by the alloy composition whereas the period is found to be independent of the compositional parameters in ternary semiconductors. The corresponding results for parabolic energy bands are also obtained from the expressions derived.
