Amorphous matrices having dispersed cesium

摘要

A composition of matter in the form of an amorphous matrix having cesium dispersed therein is disclosed. The composition is capable of cold cathode emission, thus emitting electrons at wide range of temperatures, including room temperature. The matrix can be formed from amorphous diamond, diamond-like carbon, and other materials as well. Methods of making an amorphous matrix using single and multi-ion beam techniques are also disclosed.
