We struggle through youth, and climb in our career with difficulty, but when we reach the peak of adulthood, it is all downhill after that. 我們在青春期奮斗，艱難地在生涯上攀升，然而當成年時(shí)抵達了人生的頂點(diǎn)，在那之后的將只有下坡路。
In addition, the emission peak of 20-layer SiGe QDs sample is observed 16 meV higher than that of 5-layer SiGe QDs sample due to more relaxation during growth. 此外，我們也觀(guān)察到二十層矽鍺量子點(diǎn)樣本的發(fā)光頂點(diǎn)波長(cháng)的能量比五層矽鍺量子點(diǎn)樣本要高出千分之十六電子伏特，這是由于二十層矽鍺量子點(diǎn)在成長(cháng)過(guò)程中所受應力松弛較多的緣故。
