Description
The aim of our work is to extract the density of states (DOS) and the gap function from the tunneling conductance data at higher temperatures. It is known that if the temperature approaches zero, the DOS function is proportional to the tunneling conductance, and therefore, it can be easily extracted. However, with increasing temperature, the temperature smearing causes that this approximation can no longer be used. Thus, we have developed an algorithm that was designed to extract the details of the DOS function and the gap function on a typical temperature scale, which can be used approximately up to $1/2$ of $T_c$. Moreover, knowledge of the DOS in its normal state plays an important role. Hence, we present the results of the testing data sets and also the outcome from experimentally measured tunneling conductance data of the Nb$_3$Sn superconductor.
