“…In order to obtain the electron bombardment for a photoconductor, a vacuum diode-type cold cathode device , was designed for exploring the EBIPC mechanism, which is shown schematically in Figure . A ZnS photoconductor has been used as a target in the image intensifier of camera tubes for use in low-light detection , and exhibits the advantages of high exciton binding energy, large-area fabrication, low cost, and ease of integration. , As such, it is of great promise for use in large-area and highly sensitive detectors. ZnO NW field emitters have been used in large-area flat panel vacuum devices.…”
