The simple theoretical analysis of the specific heat capacity in nano materials

An attempt is made to study the specific heat capacity in quantum wells (QWs) of bismuth (Bi) under magnetic quantization in accordance with McClure Choi, Cohen, Lax and parabolic ellipsoidal band models respectively taking all types of anisotropies of the energy band constants within the frame work of k.p formalism. On the origin of formulation, it has been found that the specific heat capacity (SHC) increases with increasing concentration and decreasing film width in various oscillatory manners and the nature of oscillations are totally band structure dependent. Now the well-known results for wide gap materials have been obtained as special cases of our generalized theory under definite limiting conditions and generalized analysis is also applicable for other types of magneto quantum wells (MQWs).
