Probing Topological Surface States and Conduction via Extended Defects in (Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ Films

Abby Liu, Armando Gil, Moon-ki Choi +10

(Bi $_{1 - x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ alloys are non-degenerate topological insulators (TIs) whose Dirac point (DP) can be tuned within the bulk bandgap by varying the composition, effectiv…

Elastic plate basis for the deformation and electron diffraction of twisted bilayer graphene on a substrate

Moon-ki Choi, Suk Hyun Sung, Robert Hovden +1

A basis is derived from elastic plate theory that quantifies equilibrium and dynamic deformation and electron diffraction patterns of twisted bilayer graphene (TBG). The basis is d…
