Towards the control of power dissipation through the use of many-body Coulomb correlations

Power dissipation constitutes a major constriction in modern and future nanoelectronic design [1]. In this context, predictive models elucidating new criterions to control Joule heating would be valuable. In this work we reveal how an accurate formulation of the many-body Coulomb correlations among carriers can lead to new perspectives on the design of power-optimized electron devices. In particular, we show that for a ballistic semi-classical system the rate at which carriers gain (or loose) kinetic energy is a function of carrier-carrier correlations and differs in general from the expected value (I)· (ΔV).
