Abstract

High-field electroluminescence offers the promise of large area solid-state displays with a wide range of applications. It also presents a challenge to our understanding, requiring a synthesis of atomic and solid-state physics. Early work was on copper-doped ZnS AC powder panels which were spatially heterogeneous, amenable to precise measurement of only macroscopic properties, and unreliable. Recent devices use thin films of ZnS:Mn which are better defined physically. In addition, Schottky diodes on n-type ZnS:Mn have been used to study particular physical mechanisms.
