摘要:GaSe microbelts were successfully synthesized using Ga/Ga(2)Se(3)as the precursor mixture, where excess Ga was required to serve as the metal catalyst. Meanwhile, a spontaneously oxidized surface amorphous oxide (GaOx) layer formed, which induced a built-in electric field perpendicular to the surface. Benefiting from this effect, a GaSe microbelt-based photodetector attained a high responsivity of similar to 3866 A W(-1)and a photoconductive gain of up to similar to 1.06 x 10(4). This study sheds light on the controlled synthesis of microstructures and provides a device design concept for high-performance micro/nano optoelectronics.
