Abstract
In this thesis, we take a stochastically driven single level quantum dot embedded between
two metallic leads at di erent temperatures which works as a heat engine. We analytically
study the optimized e ciency that lies between the maximum e ciency and minimum
e ciencies (e ciency at maximum power and the minimum e ciency) condition. We
perform two ways of optimization criteria to nd their corresponding optimized e cien-
cies, powers and periods. We study the performance of the heat engine by introducinng
a gure of merit as a function of Carnot e ciency
