Amorphous Silicon Top-Gate-Gap TFTs for Front-Illuminated Optical Sensors
Description:
The amorphous silicon top gate-gap TFTs are proposed for front-illuminated optical sensors in this work, which is identical to the process of standard VA TFT-LCD arrays. The proposed top gate-gap TFT exhibits distinct photocurrent in both the on and off regions. The length of gap has an impact on the photocurrent of top gate-gap TFTs, and the maximum dynamic range and photocurrent can achieve 128 dB and 1.86E-7A, respectively.
