Effect of substrate temperature on the deposition of Al-doped ZnO thin films using high power impulse magnetron sputtering
Martin Mickan, Ulf Helmersson, David Horwat
Al-doped ZnO thin films were deposited using reactive high power impulse magnetron sputtering at substrate temperatures between room temperature and 600 C. Two sample ser…
Enhanced Thermoelectric Properties By Embedding Fe Nanoparticles Into CrN Films For Energy Harvesting Applications
Daria Pankratova, Khabib Yusupov, Alberto Vomiero +6
Nanostructured materials and nanocomposites have shown great promise for improving the efficiency of thermoelectric materials. Herein, Fe nanoparticles were imbedded into a CrN mat…
Nanowire design by magnetic collection of Fe, Ni and/or FeNi-alloy nanoparticles
Sebastian Ekeroth, Robert Boyd, Nils Brenning +1
A method for growing nanoparticles with different elemental compositions simply by changing pulsing parameters in a power supply is demonstrated. The technique is based on high pow…
Bipolar High Power Impulse Magnetron Sputtering for energetic ion bombardment during TiN thin film growth without the use of a substrate bias
Rommel Paulo B. Viloana, Jiabin Gub, Robert Boyda +3
The effect of applying a positive voltage pulse (Urev = 10 - 150 V) directly after the negative high power impulse magnetron sputtering (HiPIMS) pulse (bipolar HiPIMS) is investiga…
Low temperature (Ts/Tm < 0.1) epitaxial growth of HfN/MgO(001) via reactive HiPIMS with metal-ion synchronized substrate bias
Michelle Marie S. Villamayor, Julien Keraudy, Tetsuhide Shimizu +6
Low-temperature epitaxial growth of refractory transition-metal nitride thin films by means of physical vapor deposition has been a recurring theme in advanced thin-film technology…
Nucleation of titanium nanoparticles in an oxygen-starved environment, II: Theory
Rickard Gunnarsson, Nils Brenning, Lars Ojamae +3
The nucleation and growth of pure titanium nanoparticles in a low-pressure sputter plasma has been believed to be essentially impossible. The addition of impurities, such as oxygen…
Nucleation of titanium nanoparticles in an oxygen-starved environment, I: Experiments
Rickard Gunnarsson, Nils Brenning, Robert Deric Boyd +1
A constant supply of oxygen has been assumed to be necessary for the growth of titanium nanoparticles by sputtering. This oxygen supply can arise from a high background pressure in…
Synthesis of titanium-oxide nanoparticles with size and stoichiometry control
Rickard Gunnarsson, Ulf Helmersson, Iris Pilch
Ti-O nanoparticles have been synthesized via hollow cathode sputtering in an Ar-O2 atmosphere using high power pulsing. It is shown that the stoichiometry and the size of the nanop…
Molecular dynamics simulation of growth of Cu nanoclusters from Cu-ions in a plasma
Alexey A. Tal, E. Peter Müger, Igor A. Abrikosov +3
A recently developed method of nanoclusters growth in a pulsed plasma is studied by means of molecular dynamics. A model that allows one to consider high-energy charged particles i…
