Thin-Film Cold Cathode Using ZnS Layer

Abstract
A new thin-film cold cathode (TFCC), which is composed of a Sn-doped In2O3/Ta2O5/ZnS/Au, has been investigated. The TFCC, which is different from the cold cathodes reported so far, causes electron emissions by electrons flowing across the ZnS layer by a high ac-field. An average emission current of 28 nA/cm2 has been obtained. To demonstrate the electron emission from the TFCC, cathodeluminescence from phosphor coated on an anode has been observed. The mechanism of the TFCC is also discussed.
