Solar Blind Sn-alloyed Ga2O3 Schottky Photodetectors

Abstract

Solar blind UV photodetectors with a cutoff wavelength below ~280 nm and are of a great interest for variety of military and civilian applications such as missile interception, non-line-of-sight communication, flame sensing, and air/water purification. Wide bandgap alloy systems such as MgxZn1-xO and AlxGa1-xN have been widely studied and developed for solar blind applications. However, increasing the content of Mg (x > 0.33)[1] or Al (x>0.45)[2] in these ternaries to achieve true solar blind response is accompanied by issues such as phase segregation in MgZnO and film quality deterioration in AlGaN.
