dc.description.abstract | In this work, the electronic specific heat as a function of temperature has been investigated using Bardeen, Cooper and Schrieffer theory (BCS). The electronic specific heat is obtained as a function of temperature by simplified derived equations based on the BCS theory and some concepts of statistic mechanics. Analyzing the obtained equations has shown that the electronic specific heat has an exponential term and it vanishes rapidly (as exp (∆/(K_B T))/T^2) at law temperature. In addition, it confirms that there is a gap in the distribution of energy levels available to the electrons in a superconductor. Numerical calculations based on the derived equations have been applied for systems of two, three and four levels using maple software and the obtained results are reported in this paper. | en_US |
