Control of atomic reconstruction and quasi-1D excitons in strain-engineered moiré heterostructures
Shen Zhao, Zhijie Li, Zakhar A. Iakovlev +8
In two-dimensional nearly commensurate heterostructures, strain plays a critical role in shaping electronic behavior. While previous studies have focused on random strain introduce…
