Description

一种铜铟镓基光电探测器
技术领域
本发明涉及一种传感器,具体涉及一种铜铟镓基光电探测器。
背景技术
诸如智能电话、平板电脑、数字媒体播放器等的电子设备越来越多地采用光学(例如,光)传感器来控制对设备所提供的多种功能的操控。例如,电子设备通常使用光传感器来检测周围的光照条件,以控制设备的显示屏幕的亮度。典型的光传感器采用将所接收的光转变成电信号(例如,电流或电压)的光电探测器,例如光电二极管、光电晶体管等。
光传感器通常用于手势感测设备中。手势感测设备使得能够在用户没有实际触摸手势感测设备所在的设备的情况下检测物理运动(例如,“手势”)。所检测的运动可以随后被用作设备的输入命令。在实施方式中,电子设备被编程以识别不同的非接触手动作,例如左到右、右到左、上到下、下到上、里到外、外到里等。手势感测设备广泛地应用于手持电子设备中,手持电子设备例如是平板电脑设备和智能电话、以及诸如膝上型电脑、视频游戏控制台等的其它便携式电子设备。
光电探测传感器的基本功能是把入射到探测器上的光功率转换为相应的光电流。其性能的好坏直接关系到接收处理电路的精度。因此,只有选择和设计合适的光电探测器,才不会削弱接收处理电路的性能。设计时,主要考虑的是光电探测器的噪声,量子效率,响应度等几项技术指标。
在很多应用领域,例如光耦合器输出部分,往往需要将光电探测器和信号处理集成在同一块单芯片上,也即是实现光电探测器与信号处理电路的工艺兼容,而这又是一项技术十分复杂、难度相当大。
目前铜铟镓硒和铜铟镓硫在光伏和光电探测上的应用已经被广泛研究,但其中的潜力并没有被完全挖掘出来,因此基于铜铟镓硒和铜铟镓硫的光电传感器,尤其是与其它材料相结合的光电传感器还有很大的开发空间,在该领域还有很多值得发现和寻找的各种结构或结构与材料组合的光电传感器。
