ABSTRACT:
The present invention relates to a light-controlled semiconductor heterostructure component for generating microwave frequency oscillations, wherein the heterostructure comprises at least two semiconductor materials: at least one of them absorbing light by creating electron-hole pairs; and the other one of them having majority carriers with a relationship of velocity as a function of electric field that presents a region of negative slope.
