Berry curvature dipole and nonlinear Hall effect in two-dimensional Nb${}_{2n+1}$Si${}_n$Te${}_{4n+2}$

Yiwei Zhao, Jin Cao, Zeying Zhang +4

Recent experiments have demonstrated interesting physics in a family of two-dimensional (2D) composition-tunable materials Nb${}_{2n+1}$Si${}_n$Te${}_{4n+2}$. Here, we show that owing to…
