研究目的
To propose a strategy to achieve two-dimensional materials with room-temperature ferromagnetism and large perpendicular magnetic anisotropy based on transition metal embedded borophene nanosheets.
研究成果
The transition metal embedding strategy can introduce room-temperature ferromagnetism in two-dimensional borophenes, offering potential advantages for the development of practicable spintronics devices. The study provides a broad platform for low-dimensional spintronic materials and devices.
研究不足
The study is theoretical and based on first-principles calculations. Experimental realization and the effect of substrates on the properties of TM embedded borophenes need further investigation.
1：Experimental Design and Method Selection:
First-principles calculations were employed to investigate the feasibility of transition metal embedding in borophene nanosheets and to predict their magnetic properties.
2：Sample Selection and Data Sources:
The study focused on χ3 phase borophene with periodic hexagon boron vacancies as intrinsic anchor points for transition metals.
3：List of Experimental Equipment and Materials:
Computational methods were used, with no specific experimental equipment mentioned.
4：Experimental Procedures and Operational Workflow:
The adsorption behavior of transition metals on borophene was studied, followed by the investigation of the embedding process and phase transition to obtain diverse structures.
5：Data Analysis Methods:
The magnetic ground state, Curie temperature, and magnetic anisotropy energy of the TM embedded borophenes were analyzed using classical Heisenberg Hamiltonian and Monte Carlo simulations.
