Synthesis and high-temperature ferromagnetism of Fe-doped SiGe diluted magnetic semiconductor thin films

Abstract

Fe-doped SiGe (Si0.25Ge0.75:Fex, x = 0.01, 0.025, and 0.05) thin films are prepared by radio frequency magnetron sputtering and subsequent rapid thermal annealing on Ge (100) substrate and their structural,...

The Influence of Temperature on the Photoelectric Properties of GeSe Nanowires

“…In the Raman spectrum shown in Figure 1 b–f, we successfully observed three main vibrational modes, located near 81 cm −1 (A g3 mode), 150 cm −1 (B 3g mode), and 188 cm −1 (A g1 mode). These results are highly consistent with previous research reports on the Raman peak positions of GeSe [ 25 , 26 , 27 ], thereby confirming the structure and composition of the synthesized GeSe nanowires.…”

Enhancing Magnetic Damping under GaAs Band-Edge Photoexcitation in a Co2FeAl/n-GaAs Heterojunction

“…Semiconductor (SC) spintronics based on the ferromagnetic SCs − and ferromagnet (FM)/SC heterojunctions , have attracted considerable attention for next-generation, multifunctional spintronic device integration. The unique carrier-mediated magnetization property of ferromagnetic SCs has enabled efficient magnetization manipulation via electrical or optical carrier injection. ,, Previous studies have noted the influence of SCs on the coercive field of FMs in the FM/SC heterojunctions .…”
