例句與造句

1. Gan - based meta1 - semiconductor - metal ( msm ) structure ultraviolet photodetector has been one of the focuses of interest in recent years for its plane structure , fabrication simplicity , and easy integration . however , the mechanisms of the i - v characteristics under illumination , the photocurrent gain and the strong persistent photoconductivity ( ppc ) are still unexplained to this day
   當前, gan基msm結構紫外探測器在穩(wěn)態(tài)光照下的電流和響應度隨偏壓變化的關系、實驗中觀測到的光增益現象以及持續(xù)光電導效應( ppc ) ,都沒有明確的理論解釋,因此器件設計中難以保證gan基msm結構紫外探測器的性能。
2. It's difficult to find persistent photoconductivity in a sentence. 用persistent photoconductivity造句挺難的
