Smallest Metallic Nanorods Using Physical Vapor Deposition

Controllable growth of aluminum nanorods using physical vapor deposition

This letter proposes and experimentally demonstrates that oxygen, through action as a surfactant, enables the growth of aluminum nanorods using physical vapor deposition. Based on the mechanism through which oxygen acts, the authors show that the diameter of aluminum nanorods can be controlled from 50 to 500 nm by varying the amount of oxygen present, through modulating the vacuum level, and by...

Growth of Y-shaped nanorods through physical vapor deposition.

This work presents a proposed mechanism for fabricating Y-shaped nanorods, demonstrates the feasibility of the proposal through classical molecular dynamics simulations, and validates the simulations through magnetron sputter deposition experiments. The proposed mechanism relies primarily on the formation of stacking faults during deposition and to a lesser degree on diffusion kinetics and geom...

Physical Vapor Deposition Simulations of Microstructure Evolution

Tungsten Oxide Nanorods Array and Nanobundle Prepared by Using Chemical Vapor Deposition Technique

Tungsten oxide (WO3) nanorods array prepared using chemical vapor deposition techniques was studied. The influence of oxygen gas concentration on the nanoscale tungsten oxide structure was observed; it was responsible for the stoichiometric and morphology variation from nanoscale particle to nanorods array. Experimental results also indicated that the deposition temperature was highly related t...

Ti-Cr-N Coatings Deposited by Physical Vapor Deposition on AISI D6 Tool Steels

In this study, physical vapor deposition (PVD) Ti-Cr-N coatings were deposited at two different temperatures 100 and 400ºC on hardened and tempered tool steel substrates. The influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and Young’s modulus were evaluated. Phase compositions were st...
