求高手解释sub-band-gap是什么意思~~还有sub-band-gap效应指的是什么,,,我要是搜相关的中文文献应该搜什么才有这种效应的解释?每次放了金币没人来领,,所以放的有点少,,金币可追加~~
Band-gapResponse timeDeep defectsSince AlN is a wide band-gap semiconductor it is usually not possible to induce photocurrents with light below 6.2 eV of energy. However, employing high power density laser pulses of 266 nm (4.66 eV) and 532 nm (2.33 eV), we succeeded to monitor the ...
It was found that, with the grain size increased from 0.5 to 40 渭m, the sub-band-gap photoconductivity measured under the constant photocurrent mode was lowered by up to a maximum of five orders of magnitude, and accompanied by a decrease in the Rose exponent 纬 . This is indicative of...

Room-temperature infrared sub-band gap photoresponse in silicon is of interest for telecommunications, imaging and solid-state energy conversion. Attempts to induce infrared response in silicon largely centred on combining the modification of its electro
Hyperdoping silicon with impurities is considered an attractive method to develop an intermediate band solar cell in silicon with the potential to increase the photovoltaic cell efficiency beyond that of the Shockley-Queisser limit by utilizing sub-band gap photons for energy generation. Unfortunately, ...
