Sažetak
An attempt is made to study theoretically the effect of a quantizing magnetic field on the electronic heat capacity in quaternary alloys at low temperatures. It is found, taking In1-xGaxAsyP1-y lattice matched to InP as an example, that the electronic heat capacity shows an oscillatory magnetic field dependence as is expected because of the dependence of the same capacity on the Fermi energy which oscillates with changing magnetic field. The amplitude of oscillations is, however, found to be significantly influenced by the alloy composition whereas the period is independent of the compositional parameter in quaternary alloys. In addition, the corresponding results for parabolic energy bands are also obtained from the expressions derived.
