2D analysis of sputtered species transport in high-power impulse magnetron sputtering (HiPIMS) discharge

open access: yesJournal of Applied Physics
Among the numerous advantages of the high-power impulse magnetron sputtering (HiPIMS) technique, the most important is the enhanced ionization degree of sputtered species contributing to the film growth. Consequently, the quality of deposited thin films is highly improved.

Investigation of plasma ion composition generated by high-power impulse magnetron sputtering (HiPIMS) of graphite

open access: yesJournal of Physics: Conference Series, 2019
Abstract High-power impulse magnetron sputtering (HiPIMS) of graphite is used to increase the density of the plasma (up to 1013 cm−3) and the fraction of ionization of carbon (up to 70 %). It makes possible to increase the ion bombardment of the growing film by applying a negative high-frequency (HF) bias potential to the substrate ...

Chromium Coatings Applied to Zr Alloy Claddings by Cathodic Arc Ion Plating: Effect of Nitrogen Inclusion on Limiting Columnar Defects

open access: yesAdvanced Engineering Materials, Volume 26, Issue 20, October 2024.
The nitrogen incorporation effectively mitigates columnar defects in chromium‐based coatings on the Zr alloy claddings. The important significance of chromium‐based coatings is that they are suitable material candidates for accident‐tolerant fuel cladding of nuclear fuel rods.

Laterally Modulating Carrier Concentration by Ion Irradiation in CdO Thin Films for Mid‐IR Plasmonics

open access: yesAdvanced Optical Materials, Volume 12, Issue 30, October 24, 2024.
Ion irradiation through a patterned photoresist mask enables in‐plane control of transport and optical properties in CdO thin films. This proof‐of‐concept demonstrates a simple grating pattern of alternating high and low carrier concentrations (irradiated and non‐irradiated) which exhibit sharp optical contrast in the near‐field and surface plasmon ...

Large Mid‐Infrared Magneto‐Optic Response from Doped Cadmium Oxide at Its Epsilon‐Near‐Zero Frequency

open access: yesAdvanced Optical Materials, Volume 12, Issue 25, September 3, 2024.
The high plasmonic quality of doped CdO is shown to enhance its magneto‐optic response near the epsilon‐near‐zero frequency, leading to a large peak in the Verdet constant that can be tuned throughout the mid‐infrared. The ability to deposit CdO on Si with no loss in performance makes this material a promising platform for integrated mid‐infrared ...

Reactive DC Sputtered TiO2 Electron Transport Layers for Cadmium‐Free Sb2Se3 Solar Cells

open access: yesAdvanced Energy Materials, Volume 14, Issue 34, September 13, 2024.
Evolution of Sb2Se3 heterojunction devices away from CdS electron transport layers to wide bandgap metal oxide alternatives is a critical target in the development of this emerging photovoltaic material. The dependence of TiO2 processing conditions on the series resistance of complete Sb2Se3 devices is demonstrated.
