Solutions

Gallium nitride (GaN) is a compound of nitrogen and gallium. It is a semiconductor with a direct bandgap of Group III and Group V elements. Since 1990, it has been commonly used in light-emitting diodes (LEDs). The structure of this compound is similar to that of wurtzite, and it has a high hardness. Gallium nitride has a wide bandgap of 3.4 electron volts, and it can be used in high-power and high-speed optoelectronic devices. For example, gallium nitride can be used in violet laser diodes, which can generate violet (405 nm) laser light without the use of a nonlinear semiconductor-pumped solid-state laser (Diode-pumped solid-state laser).

Its sensitivity to ionizing radiation is low (similar to other Group III nitrides), making it a suitable material for the solar cell arrays of artificial satellites...

解决方案

氮化镓（GaN、Gallium nitride）是氮和镓的化合物，是一种III和V的直接能隙（direct bandgap）的半导体，自1990年起常用在发光二极管中。此化合物结构类似纤锌矿，硬度很高。氮化镓的能隙很宽，为3.4电子伏特，可以用在高功率、高速的光电元件中，例如氮化镓可以用在紫光的激光二极管，可以在不使用非线性半导体泵浦固体激光（Diode-pumped solid-state laser）的条件下，产生紫光（405 nm）激光。

其对电离辐射的敏感性是低的（如同其他III族氮化物），使得它成为用于人造卫星的太阳能电池阵列的合适材料……
