Optimizing SiGe–SiO2 Visible–Short‐Wave Infrared Photoresponse by Modulating Interplay Between Strain and Defects Through Annealing

Advanced Photonics Research, Volume 5, Issue 8, August 2024.
The beneficial effect of rapid‐like furnace annealing (FA) on photoconductive response of SiGe nanocrystals (NCs)‐based structures is revealed by comparison to rapid thermal annealing. FA structures present photocurrent spectra with enhanced intensity of peaks due to strain, explained by the short annealing time for NC formation without reaching ...

Tensile properties and drawability of thin bimetallic aluminum-scandium-zirconium / stainless steel foils and monometallic Al-Sc-Zr fabricated by magnetron sputtering

MATEC Web of Conferences, 2018
Al-Sc-Zr alloys are interesting for the production of high strength micro components by micro deep drawing. These alloys show a good hardenability due to the formation of nanometer-scale spheroidal Al3(Sc, Zr) precipitates, which are highly coherent with

ZrB2 thin films grown by high power impulse magnetron sputtering from a compound target

Thin Solid Films, 2012
Abstract ZrB 2 thin films were grown on Si by high power impulse magnetron sputtering (HiPIMS) from a compound target in an industrial deposition system. By keeping a constant average power while modifying the HiPIMS pulse repetition frequency, the pulse peak current and thereby the degree of ionisation was varied. The films were characterised using
