Abstract ：We investigate the electronic-current-induced heat generation in a double quantum dot connected by two normal leads. The dots are coupled in series with a coupling strength td . It is found that, at zero temperature and weak dot-lead coupling, td affects the heating and current heavily. In particular, the effects on the heat generation and on the current are quite different. For example, at a heating valley the current can exhibit a deep valley, a plateau, or a high peak depending on td . As a result, we can find an ideal working condition, large current while small heating, for the double dots system by tuning the interdot coupling strength.
