Abstract: In this paper we present a quantum transport study of quantum dot in steady state in presence of static gate potential. We consider a quantum dot coupled to the two metallic leads. The quantum dot under study is modelled through Anderson Impurity Model (AIM) and the hopping parameter modulated through voltage drop between leads and the dot central region. Based on the Landauers formula derived from Non Equilibrium Greens Function and Single electron theory, the essential ingredients of transport properties are revealed. We show that the results out of two approaches closely agree with each other.
