Abstract:In this letter, we reported a self-powered periodic inverse micropyramid (PIMP)-Si/graphene photo-diode with high responsivity, specific detectivity and fast response speed of 0.78 A W-1, 3.83 x 10(14)Jones and 226/364 mu s for rise/fall time at zero bias upon 880 nm illumination, respectively. It was found that the introduction of ultrathin interfacial oxide layer can passivate surface states and thereby lead to an excellent current stability, which enables high-quality Fourier single-pixel imaging (FSI). A 256 x 256-pixel image achieved at 7.79% sampling rate showed the peak-signal-to-noise ratio (PSNR) of28.3 dB and structural similarity index measure (SSIM) of0.50, revealing the high-quality single-pixel imaging (SPI).
