photoresponse

Base on this structure, the photoresponse of each spectral shape is tunable by the period of gratings.

我们可以利用各种不同周期的光栅结构来调变响应的波形。

Due to dopant migration, build-in electric field exists in the device.There is open-circuit photoresponse, the detector can operate in photovoltaic mode.

元件受掺杂移移的影响而存在内建电场，使得元件有开路响应，存在光致电压模式。
