FIELD: physics.
SUBSTANCE: disclosed is the design of a beta radiation-to-electrical energy semiconductor converter, having a semiconductor plate with a textured surface, a diode structure along the textured surface and a layer of radioactive substance on the textured surface. The textured surface of the semiconductor plate is in form of a plurality of through-channels having the shape of a circle, an oval, a rectangle or another arbitrary shape, and the radioactive substance, which contains a nickel-63 radionuclide, tritium or both, covers the walls of the channels and a large part of the remaining surface of the semiconductor plate.
EFFECT: simplification of the method and low cost of making a beta radiation converter, as well as increase in specific electric power and reliability thereof.
