Spiral Edge States in Topological 2D Sb2Te3 Crystals
Timothy Carlson, Daniel Lazega, Scott McGuire +7
This work explores the edge state conduction properties of twinned and spiraled, 2D Sb2Te3 topological insulator crystals. We show the structure supports spatially continuous edge…

Geometry-tunable magnetic edge contrast in Bi2Te3 Corbino nanoplates
Motahhare Mirhosseini, Swathi Kadaba, Allison Swyt +1
Two-dimensional topological insulators feature helical edge states that are remarkably resistant to disorder, making them appeal for energy-efficient electronics and quantum inform…

Anomalous Edge Contrast in Magnetic Force Imaging of 2D Topological Insulators
Timothy W. Carlson, Swathi Kadaba, Allison Swyt +10
Magnetic force imaging (MFM) of 2D topological insulators, such as crystalline plates of Bi2Te3 and Bi2Se3, reveals anomalously large contrast around the plate edges even under amb…
