Description
Nanocrystalline diamond films were synthesized by chemical vapor deposition and characterized to explore their potential device applications. Electrical conductivity measurements at low temperatures and high magnetic fields showed weakly localized transport in three dimensions in ultra-nanocrystalline diamond films. Also a semi-classical model is developed to explain their unusual magneto-resistance properties.
