1. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth
University essay fromAbstract : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. READ MORE

2. Photocatalytic activity of titanium dioxide thin films deposited with high power impulse magnetron sputtering
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : High power impulse magnetron sputtering has shown a lot of promise as a way of depositing photocatalytic thin films of titanium dioxide at low temperatures, however, the films deposited are often amorphous and display uncertain photocatalytic abilities. This thesis explores the deposition and characterization of photocatalytic thin films deposited with high power impulse magnetron sputtering. READ MORE

3. Multicomponent TiNbCrAl nitride films produced by DCMS and HiPIMS
University essay from Linköpings universitet/TunnfilmsfysikAbstract : High entropy alloys (HEAs) are made of at least five principal elements in near-equimolar proportions. The vast number of possible alloys and unconventional combinations of properties are the main benefits of HEAs. Ti, Nb, Cr, Al and N were chosen in order to create a hard, corrosion resistant coating with good thermal stability. READ MORE

4. Modeling of carbon plasma discharges in high-power impulse magnetron sputtering
University essay from Linköpings universitet/Plasma och ytbeläggningsfysikAbstract : Diamond like carbon (DLC) is a metastable state of amorphous carbon that has very important and wide-ranging thin film applications. DLC has a strong resemblance to pure diamond and exhibits many traits of real diamond, like mechanical hardness and chemical inertness, but with a drastically lower deposition cost. READ MORE

5. Experimental Verification of BP-HiPIMS Thrusters
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The ion acceleration process in Bipolar High Power Impulse Magnetron Sputteringis investigated for use in a novel space propulsion system - the BP-HiPIMS thruster.The interest for BP-HiPIMS has recently been growing within the area of thin filmdeposition due to the theorised acceleration of target ions caused by the reversedpulse following the regular HiPIMS pulse.
