Abstract
A thermal diode for a photosensor of a thermal imaging camera includes a semiconductor substrate having a surface and two doped structures set apart from each other on the surface. Furthermore, a device is provided for influencing a current between the first and the second structure, in order to reduce a current density in an area near to the surface and to increase it in an area far from the surface. In addition, a topology having an even absorption layer is proposed. The measures proposed have the aim of realizing a low-noise diode for thermal applications.
