研究目的
Investigating the epitaxial growth of Mn5Ge3 films on Ge (100) substrates using flash lamp annealing for potential applications in spintronic devices.
研究成果
The epitaxial growth of a ferromagnetic Mn5Ge3 (100) layer on a Ge (100) substrate by flash lamp annealing was achieved, with a sharp interface between Mn5Ge3 and the Ge substrate. The Mn5Ge3 film exhibits ferromagnetism with a Curie temperature of 283 K and an in-plane magnetic easy axis, promising for high-efficiency spin injection in spintronic devices.
研究不足
The study is limited to the growth and characterization of Mn5Ge3 films on Ge (100) substrates using flash lamp annealing. The compatibility with CMOS technology is suggested but not fully explored.
