Valley filtering in strain-induced $\alpha$-${\mathcal{T}}_3$ quantum dots

Alexander Filusch, Alan R. Bishop, Avadh Saxena +2

We test the valley-filtering capabilities of a quantum dot inscribed by locally straining an $\alpha$-${\mathcal{T}}_3$ lattice. Specifically, we consider an out-of-plane Gaussian bump in…
