Kavli Affiliate: Jing Wang | First 5 Authors: Huan Wang, Zhaochen Liu, Yadong Jiang, Jing Wang, | Summary: We propose a general theory of anisotropic band flattening in moir’e systems at the $Gamma$ valley. For a two-dimensional semiconductor with a rectangular unit cell of $C_{2z}$ or mirror symmetries, we find that a larger effective mass […]
