Abstract
Apparatus and method for establishing a temperature gradient, comprising at least one gas-tight working space having a first boundary layer that is connected to a first electrode and a second boundary layer that is connected to a second electrode, wherein when an electric voltage is applied between the first electrode and the second electrode in the working space, an electric field can be produced between the first boundary surface and the second boundary surface, and wherein a distance between the first boundary surface and the second boundary surface is less than 5000 nm, wherein the first boundary surface comprises at least one field-enhancement device, in particular a peak, so that if an electric voltage is applied to the electrodes, a field strength of the electric field in a region of the field-enhancement device is greater than an average field strength of the electric field in the working space.
