Abstract :
A monolithic multi-terminal logic device that functions both optically and electrically as an "ORNAND" gate, is demonstrated for the first time. The device, based on the real-space transfer of hot electrons into a complementary collector layer, has been implemented in MBE-grown InGaAs-InAlAs heterostructure. Excellent performance is obtained at room temperature. The output current and optical power both exhibit OR and NAND functions of voltages of any two of the three input terminals, these functions being interchangeable by the voltage on the third terminal.<>
