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。

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

件受掺杂移移的影响而存电场，使得件有开路响应，存光致电压模式。
