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…

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…

Second-Order Nonlinear Circular Dichroism in Square Lattice Array of Germanium Nanohelices
Grégoire Saerens, Günter Ellrott, Olesia Pashina +5
Second harmonic generation (SHG) is prohibited in centrosymmetric crystals such as silicon or germanium due to the presence of inversion symmetry. However, the structuring of such…
