Cathode ray tube with single crystal targets.

摘要

Light output of single crystal phosphors used on cathode ray tubes can be vastly improved by use of a microfaceted surface structure conveniently produced by use of a single crystal epitaxial layer (e.g. 32) with lattice constant slightly larger than the single crystal substrate (e.g. 3l). Such epitaxial layers are conveniently grown using substituents that increase the lattice constant compared to the single crystal substrate.
