Abstract

Negative differential velocity in nonintentionally doped GaAs/A1As superlattices has been evidenced by an optoelectronic picosecond time-of-flight experiment in the temperature range from 10 K up to 300 K. In the same structures bursts of high frequency oscillations up to 61 GHz are optically induced in the same temperature range. Experimental records are correctly reproduced by numerical simulations in the classical drift- diffusion approximation. A particular design of the superlattice structure gives high yield of mm-wave/optical excitation conversion.
