  ABSTRACT: The discovery of iron pnictides in 2006 added on the number of materials that have the potential to transmit electricity with close zero d.c resistance. High-temperature iron-based superconductors have been obtained through modification, mostly by doping, of the initially low-temperature iron-based superconductors. Unlike in LTSC, the energy gap in HTSC requires a theory, beyond spin fluctuations, to explain its anisotropy. This study seeks to establish a common ground between iron pnictides and cuprates towards explaining high temperature superconductivity. There is a general consensus on the existence of Cooper pairs in these systems. In addition to this, experimental results have revealed the existence of electron-boson coupling in iron pnictides. These results make it viable to study the interaction between an electron and a Cooper pair in iron based superconductors (IBSC). In this study, Bogoliubov-Valatini transformation has been used in determining the electronic specific heat based on the interaction between an electron and a Cooper pair in high-temperature IBSC, namely, Ca0.33Na0.6Fe2As2 and SmFeAsO0.8F0.2. We record the theoretical electronic specific heat of CeFeAsO0.84F0.16 and SmFeAsO0.8F0.2 as 164.3 mJ mol-1 K-2 and 101.6 mJ mol-1 K-2 respectively.
