蓝绿光激光二极管技术的进展砷化镓和有关Ⅲ－Ⅴ族材料之类的化合物半导体一般在红外光谱区发射，这类器件的应用是光纤通信线路和ＣＤ唱机。但宽带隙Ｄ－Ｗ族化合物半导体可有一系列直接能隙，能在整个可见光谱范围发射，潜在效率较高。因此，直接带隙Ｄ－Ｉ族半导体器件... Advances in blue-green laser diode technology Gallium arsenide and compound semiconductors such as group III-V materials are generally emitted in the infrared region of the spectrum, and these devices are used for optical fiber communication lines and CD players. However, wide bandgap D-W compound semiconductors can have a series of direct energy gaps that can be emitted over the entire visible spectrum, potentially with high efficiency. Therefore, the direct band gap D-I semiconductor device ...
