摘要：
通过第一性原理计算发现的Janus VSBrI单层，是一种兼具铁磁和铁电特性的理想半导体材料。其面内磁各向异性能高达460 μeV/V，面内和面外压电应变系数均大于许多其他已知的二维材料。不同磁态间的能量变化与极化表现出强相关性。有趣的是，施加双轴拉伸应变可进一步增强其铁电相的稳定性。这些特性使Janus VSBrI单层在压电电子器件的实际应用中极具吸引力，并成为多功能自旋电子器件的有力候选者。
英文摘要：
The Janus VSBrI monolayer, identified by first-principles calculations, emerges as a promising semiconducting material with desirable ferromagnetic and ferroelectric properties. It's in-plane magnetic anisotropic energy is up to 460 $μ$eV/V , and in-plane and out-of-plane piezoelectric strain coefficients are larger than many other known two-dimensional materials. The energy variations among different magnetic states show a strong correlate with polarization. Interestingly, the stability of the ferroelectric phase can be further enhanced by the application of biaxial tensile strain. These intriguing properties make the Janus VSBrI monolayer highly desirable for practical applications in piezoelectronic devices, and a promising candidate for multifunctional spintronic devices.
