Effect of Negative Ion on Growing of Diamond Structure

Abstract

The authors have studied on the growing mechanism of diamond structure using negative ions by physical vapor deposition technique. It is considered that diamond structure will be changed to graphite structure by positive ions, because ionization energy causes thermal chemical reaction. On the contrary, negative ions restrain thermal chemical reactions, because of electron affinity. From the experimental results, it is shown that negative ions were more effective than positive one to grow of diamond structure.
