Description
Summary:Calculations of heat transfer between two plates of gold in an extreme near field is performed taking into account the existence of the electrical double layer on metal surfaces. For d < 3 nm the double layer contribution to the heat flux exceeds the predictions of the conversional theory of the heat transfer by several orders of magnitudes. The predicted effect is not related with bias voltage but occurs due to intrinsic properties of the electrical double layer. The results obtained can be used for the heat management at the nanoscale by intentionally changing the parameters of surface dipoles with the help of engineering.
