✦ Synopsis

The electronic structure and the heat capacity of multi-quantum well and wire structures in strong magnetic fields are calculated. The specific heat as a function of magnetic field shows strongly oscillating behavior. For a well structure in the presence of tilted fields, the hybrid-quantization of electronic energies reveals the variation of width and the non-uniform spacing of energy levels in each branch of the Landau fan and sometimes causes the intralevel contribution to have asymmetric shapes. For a wire structure, the specific heat consists of sets of asymmetric double peaks and shows a non-linear dependence on the temperature in contrast to the well case.
