Synthesis of boron doped continuous diamond film by microwave assisted plasma enhanced chemical vapour deposition

Diamond has many attractive properties such as high hardness, good durability and excellence heat conductivity. The diamond synthesis technique has become a popular topic to research because of diamond`s rareness and useful. Plasma enhances chemical vapour deposition (PECVD) is one of the popular me...

Synthesis of boron doped continuous diamond film by microwave assisted plasma enhanced chemical vapour deposition
description Diamond has many attractive properties such as high hardness, good durability and excellence heat conductivity. The diamond synthesis technique has become a popular topic to research because of diamond`s rareness and useful. Plasma enhances chemical vapour deposition (PECVD) is one of the popular method for diamond synthesis. It produces high quality diamond and relatively easy to control. The basic mechanism for PECVD was investigated. And the choosing of precursor, the role of different gas, and the effect of parameter changing to diamond deposition were reviewed and discussed. Previoous literatures mainly utilized high power microwave source to generate plasma. The power for high power microwave source is usually 3~4kW.
