Abstract:
1. A laser-radiation sensor, comprising: a copper substrate; an oriented polycrystalline buffer-layer deposited on a surface of the substrate, the buffer-layer having a crystal-orientation at a first angle between about 10 degrees and about 45 degrees relative to a normal to the surface of the substrate; an oriented polycrystalline sensor-element of a thermoelectric material selected from the group of thermoelectric materials consisting of dysprosium barium cuprate, strontium sodium cobaltate, and strontium cobaltate deposited on the buffer layer, the sensor-element having a crystalline c-axis orientation at a second angle between about 10 degrees and about 45 degrees relative to the normal to the surface of the substrate; two or more protection layers deposited on the sensor-element; a radiation-absorber layer deposited on the uppermost protection layer; and first and second elongated electrodes spaced apart in electrical contact with the sensor-element.
