[物] 受激能带
... excited atom 激发原子 excited band 受激能带 excited ion 受激离子 ...
几周以前,我给女朋友买了一台Wii和Rock Band 2,而我敢肯定我比她更兴奋。
The extra electron fills up the lower-energy state in the conduction band, causing excited electrons to, effectively, spill over into the higher-energy, photon-emitting state.这个额外的电子填充了传导带的较低能级,有效的导致了被激发的电子溢入较高,释放光子的能级。
The second strategy was to lower the energy difference between the two conduction-band states so that excited electrons would be more likely to spill over into the photon-emitting state.第二步策略是减小两个传导带态的能量落差,这样一来受激发电子就更容易溢入光子释放态。
