常見例句We find that the photocurrent of this device is not reduced by the additional MQWs but the dark current is.我們發(fā)現(xiàn)超晶格所產(chǎn)生的光電流并沒有因為量子井結(jié)構(gòu)而降低，但暗電流卻有減少。The thermally generated dark current intrinsic to the photodiodes is always working to charge the diode.光電二極管固有的熱產(chǎn)生的暗電流不斷為二極管充電。 返回 dark-current
