Abstract
Micrometer-sized single-crystal GeSe nanosheets have been synthesized by a solution method. The single GeSe nanosheet exhibits novel anisotropic photoresponse properties in two photodetectors based on individual nanosheet. The on/off switching ratio of the photodetector perpendicular to the nanosheet is 3.5 times higher than that parallel to the nanosheet.
摘要
微米级单晶 GeSe 纳米片通过溶液法合成。单个 GeSe 纳米片在两个基于单个纳米片的光电探测器中表现出新颖的各向异性光响应特性。垂直于纳米片的光电探测器的开关比是平行于纳米片的光电探测器的 3.5 倍。
