| Abstract(in English) | We have developed an stacked image sensor using a thin-film crystalline selenium (c-Se) as a photoconversion layer. The dark current was significantly decreased by applying an n-type wide-band-gap gallium oxide (Ga2O3) layer as a high hole-barrier against injected carriers. We herein present the first high-resolution images obtained with such a device by changing the thickness of c-Se films to decrease a size of particles much smaller than the pixel size. |
