| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We report a new method to evaluate current collapse. To exclude self-heating effect during dynamic test, we propose carrier number as a new indicator. Carrier number could be evaluated from capacitance measurement. Change in capacitance gives direct evidence of carrier decrease and the region it occurs. Proposed method was verified and confirmed to have a high accuracy by comparing with dynamic testing results. New method makes it possible to evaluate the change of carrier number and mobility independently, which can be used to model and solve the current collapse phenomenon. | |
