Abstract
Diamond and diamond-like carbon (DLC) layers are nowadays of increasing importance for electrical and mechanical applications. In our laboratory we grow diamond on different substrates (Si, WC-Co) using Hot Filament Chemical Vapor Deposition (HF CVD)method improved by double biasing and DLC layers using pulsed arc system again on different substrates (Si, Ni, glass, Ti-6Al-4V, steel, WCCo). Growth parameters facilitate to control crystallinity of diamond layers from microcrystalline to nanocrystalline type. Mechanical, electrical and optical parameters are possible to change using doping with hydrogen, nitrogen, or oxygen. The goal of this article is to summarize recent results achieved in our laboratory related to applications of diamond and DLC layers for their use in sensors of hard metal in water and medical implantable joints.
Highlights
Carbon is the sixth most abundant element in the universe
Recent progress in chemical vapor deposition (CVD) diamond technology has enabled the preparation of high-quality n-type CVD diamond layers using phosphorus as an n-type dopant and boron, nitrogen, hydrogen as p-type dopants
CVD diamond can be considered as a new interesting conventional wide-gap semiconducting material having both n-type and p-type conductivity, which makes it attractive for numerous applications in high-temperature, high-voltage and high-frequency devices [3]
Summary
Carbon is the sixth most abundant element in the universe. Carbon is a very special element because carbon is your body, food you eat, clothes you wear, cosmetics you use and gasoline that fuels your car. Electromagnetic radiation transparency range of any material, as well as wide bandgap and high carrier mobilities. CVD diamond can be considered as a new interesting conventional wide-gap semiconducting material having both n-type and p-type conductivity, which makes it attractive for numerous applications in high-temperature, high-voltage and high-frequency devices [3]
