摘要 利用正向交流(a.c.)小信号方法对发光二极管(LEDs)的电容-电压特性进行了研究,观察到了发光二极管中的负电容现象,并且测试频率越低、正向偏压越高,负电容现象越明显,给出了证实负电容确实存在的判定性试验. An experimental study on the capacitance-voltage characteristic of LEDs was presented by using alternating current （a,c） small-signal method. Negative capacitance phenomenon was observed experimentally, and the negative capacitance phenomenon is more obvious with higher voltage or lower frequency. The existence of the negative capacitance was testified by a judgement experiment.
