The electronic characteristics of these fabricated RTD devices,MSM devices,and integrated circuits are tested at room temperature. The results show that the current peak-to-valley ratio is 4,and the photocurrent at 5V is enhanced by a factor of nearly 9,from 2 to about 18μA by use of recessed electrodes. The working theory and logical functions of the circuits are validated.展开更多
