Galnnas is a very promising new material for infrared lasers , photo detectors , solor cells and optical integration . it has much more advantages than galnasp because much better electron confinement can be achieved in this system , thus much higher the laser ' s characteristic temperature will be 由于gainnas在红外激光器,光探测器,太阳能电池以及光集成等方面巨大的应用前景和相对于gainasp的优越性,人们对ganas及gainnas的研究在最近两、三年里蓬勃发展。
