Evolution of Berry Phase and Half-Metallicity in Cr${}_2$Te${}_3$ in Response to Strain, Filling, Thickness, and Surface Termination

Sohee Kwon, Yuhang Liu, Hang Chi +3

Cr${}_2$Te${}_3$ is a ferromagnetic, quasi-two-dimensional layered material with perpendicular magnetic anisotropy, strong spin-orbit coupling, and non-trivial band topology. The non-t…
