Abstract

In this letter, we report a self-powered Ti ₃ C ₂ T _x /Si nanoholes array (SiNHA) Schottky photodiode fabricated by spin-coating Ti ₃ C ₂ T _x layer. The device exhibited enhanced photoresponse over the broadband wavelength range (265-1200 nm) and an excellent linear dynamic range (LDR, 119 dB), showing responsivity, specific detectivity and response speed of 0.97 A W

用于免滤光片彩色单像素成像 (SPI) 的 Ti₃C₂Tₓ/Si 纳米孔阵列 (SiNHA) 肖特基光电二极管

在这封信中，我们报告了一种通过旋涂 Ti3C2Tx 层制造的自供电 Ti3C2Tx/Si 纳米孔阵列（SiNHA）肖特基光电二极管。该器件在宽带波长范围（265-1200 nm）内表现出更强的光响应能力和出色的线性动态范围（LDR，119 dB），其响应率、比检出率和响应速度均为 0.97 A W $^{-{1}}$ 、1.03/times 10^{{14}}$ Jones 和 162/ $60~\mu $ s 的上升/下降时间，分别是在 970 nm 照明（光强：2.5~\mu $ W cm $^{-{2}}$ ）时的零偏压条件下。宽带光响应确保了高质量的可见光傅立叶单像素成像（FSI），通过合成以 7.79% 采样率获得的 R、G 和 B 信道单色图像，实现了 256/times 256$ 像素的彩色图像。这项工作还为无滤波器彩色单像素成像（SPI）提供了一种简单的策略。
