Electronic transport property of liquid Cd-Te alloys

Abstract

The temperature dependent electrical resistivity of liquid Cd₀․₆Te₀․₄ alloys has been studied theoretically by employing Faber-Ziman formula. Also, the Faber-Ziman formulation is used to generate the partial structure factor of the liquid Cd₀․₆Te₀․₄ alloys at 1062ºC. The electron-ion interaction is incorporated through a newly proposed local model potential alongwith Ichimaru-Utsumi (IU) dielectric screening function. Good agreement is achieved between the presently calculated results of resistivity with the experimental findings. Resistivity of liquid Cd₀․₆Te₀․₄ shows a semiconducting behaviour in the liquid phase. Thus, the resistivity data for Cd-Te system are in qualitative agreement with the nearly-free electron picture.
