High power impulse magnetron sputtering (HiPIMS) was studied during the growth of hafnium films at argon pressures ranging from 0.80 to 5.33 Pa with a fixed pulse length (50 μs) and frequency (200 Hz). The effect of inert gas pressure on the plasma

Carbon nanopearls films were deposited onto silicon substrates using MAPLE. A 248 nm KrF excimer laser was directed onto a target consisting of ~ 150 nm-sized carbon nanopearls dispersed in a solvent solution and frozen in liquid nitrogen. The morpho

Oxides are inherently stable in air at elevated temperatures and may serve as wear resistant matrices for solid lubricants. Aluminum oxide is a particularly good candidate for a matrix because it has good diffusion barrier properties and modest hardn

Pulsed laser deposition (PLD) was employed to grow MoS x –WSe y composite films, where x = 1.18, y = 0.78. Scanning electron micrographs show that the films have a dense granular morphology. Crystallization, d-spacing and hexagonal sheet curvature
