Summary: High entropy alloys are a new type of materials with unique physical properties due to single-phase solid solutions of multiple elements. Nanostructured or amorphous thin films offer increased effective surface area and high intergranular diffusion. The study of HfNbTaTiZr thin films deposited at room temperature showed a cellular structure with fine substructure, close to equimolar composition, and oxidation leading to the formation of oxide clusters.

Summary: In this study, deposition parameters for the formation of alpha-phase tungsten were identified by varying the substrate bias and argon pressure in an RF magnetron sputtering system. The negative bias triggered the phase transformation of tungsten from beta to alpha, and the effect of bias on the formation of alpha-phase tungsten and film resistivity became more pronounced as pressure increased.

Summary: SiO2 is deposited at low temperature using ICP-CVD to meet the requirements of Josephson voltage standard (JVS) chip fabrication. The sidewall profiles of SiO2 films can be adjusted by changing the RF power, ICP power, and chamber pressure. The effects of RF power on the stress, density, roughness, and breakdown voltage of the films are investigated. Under optimized conditions, the films exhibit improved densities, reduced roughness, and enhanced step-coverage profiles, leading to optimized device performance.

Summary: A bolometric thin-film-based transfer standard for absolute power detection in D-band (110-170 GHz) is presented. It utilizes a resonance-type matching technique with thin-film resistive lines, where the same line functions as the sensing element. The change in resistivity of the line under the incident wave is calibrated to measure absolute RF power in the D-band.

Summary: Cu films of different thicknesses were deposited on GaN wafers with different doping states to study element, dislocation density, and stress/strain at Cu/GaN interfaces. The stress decreased with increasing Cu thickness in undoped GaN layers. Various dislocations were observed in the undoped and Mg-doped GaN, while Si-doped GaN exhibited abundant strain extremes due to dislocation generation. The presence of interfacial stress was attributed to the difference in thermal expansion coefficients between Cu and GaN, and the Cu/GaN interfaces were predominantly semi-coherent.
