Abstract
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.
Claims8
A composition of matter comprising an amorphous matrix having cesium dispersed in said matrix, said cesium being present in substantially non-crystalline form.
A composition of matter comprising an amorphous diamond matrix having cesium dispersed in said matrix, wherein the percentage of cesium is between 0.01 and 25% of the carbon content of the matrix and the matrix has at least 50% sp.sup.3 bonding.
A composition of matter comprising a diamond-like carbon matrix having cesium dispersed in said matrix, said cesium being present in substantially non-crystalline form, wherein the percentage of cesium is between 0.01 and 25% of the carbon content of the matrix and the matrix has at least 50% sp.sup.3 bonding.
