常見例句It can be applied to an arbitary refractive index profile of the MQW waveguide. 該公式是偏振態(tài)和量子阱波導(dǎo)折射率分布的函數(shù)。Because of the lower electron mobility in the miniband, the photocurrent of SL is relatively lower than that of MQWs. 雖然超晶格結(jié)構(gòu)適合操作在低偏壓下,超晶格的光電流相較之下還是比量子井結(jié)構(gòu)的要低。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?yàn)榱孔泳Y(jié)構(gòu)而降低,但暗電流卻有減少。InGaAs/GaAs acting as the active region of MQW SEED to gain 980nm work wavelergth has been introduced. 采用 In Ga As/ Ga As作為多量子阱 SEED器件的有源區(qū) ;從而獲得了 980 nm工作波長 .The net stress is a driving force of misfit dislocation multiplication and is a very important factor for strained MQWs stability. 凈應(yīng)力是失配位錯(cuò)增殖的驅(qū)動(dòng)力,是應(yīng)變多量子阱穩(wěn)定的重要判據(jù)。By simulation, we found that there is a hetero-junction between Silicon buffer layer and Si/SiGe MQW structure. 從實(shí)驗(yàn)的數(shù)據(jù)得知,在室溫下,樣品的矽發(fā)光強(qiáng)度隨著注入電流的增加而有顯著的增強(qiáng); 返回 MQWs
