Technical singularities of the E-field that would arise at mathematically sharp edges of the grid wires are avoided in the calculations by smoothing the edges with a radius much smaller than the pitch grid size.

In the calculations, the vacuum level of all electrodes was set to be constant and the potentials for all materials were set to the same value. With this, the chemical potential is constant without voltage bias. These assumptions do not result in a loss of generality. If the work functions were different, the load applied to the device would shift the chemical potentials such that the vacuum levels were aligned (see Fig. 1), corresponding to a trivial shift of the electrode bias.

Abstract

Mobile energy converters require, in addition to high conversion efficiency and low cost, a low mass. We propose to utilize thermoelectronic converters that use 2D-materials such as graphene for their gate electrodes. Deriving the ultimate limit for their specific energy output, we show that the positive energy output is likely close to the fundamental limit for any conversion of heat into electric power. These converters may be valuable as electric power sources of spacecraft, and with the addition of vacuum enclosures, for power generation in electric planes and cars.
