Abstract
A detector of electromagnetic radiation (RL) is described. The detector comprises: a substrate (1), an oriented polycrystalline layer (2) of thermoelectric material deposited on the top surface (10) of the substrate, first and second electrodes spaced the one from the other and in electrical contact with the oriented polycrystalline layer. The substrate comprises at least one ceramic layer and the oriented polycrystalline layer has a crystal orientation at an angle comprised between 30 degrees and 55 degrees relative to a normal to the top surface of the substrate.
