| Abstract | ||
| In this study, the required injected carrier's number, current, and voltage to achieve switching dynamics in n-type InSb has been calculated theoretically. It is found that the required injected concentration at room temperature is much larger than that at liquid nitrogen temperature and the applied bias voltage and current increase linearly with increasing the injected concentration .Results show that ,the relation between the logarithm of the current versus applied bias is linear .At 77 K, for an applied bias of 143 mV the entire injection requirements to achieve switching dynamics are satisfied by 0.6 mA compared with a requirement in the range of amperes for contacts which are not fabricated to be injecting. Thus, the efficiency of injection increases considerably when a p+-n junction was used. Also, the required power to achieve switching in InSb increased as temperature increased. | ||
