Robust Super-Moiré in Large Angle Single-Twist Bilayers
Yanxing Li, Chuqiao Shi, Fan Zhang +19
Forming long wavelength moiré superlattices (MSL) at small-angle twist van der Waals (vdW) bilayers has been a key approach to creating moiré flat bands. The small-angle twist, how…
Real-Space Imaging of the Band Topology of Transition Metal Dichalcogenides
Madisen Holbrook, Julian Ingham, Daniel Kaplan +11
The topological properties of Bloch bands are intimately tied to the structure of their electronic wavefunctions within the unit cell of a crystal. Here, we show that scanning tunn…
Optical Band Engineering of Monolayer WSe2 in a Scanning Tunneling Microscope
Xuehao Wu, Thomas P. Darlington, Madisen A. Holbrook +7
Intense electromagnetic fields can result in dramatic changes in the electronic properties of solids. These changes are commonly studied using optical probes of the modified electr…
Efficient light upconversion via resonant exciton-exciton annihilation of dark excitons in few-layer transition metal dichalcogenides
Yi-Hsun Chen, Ping-Yuan Lo, Kyle W. Boschen +15
In this work, we report a pronounced light upconversion in few-layer transition metal dichalcogenides. Our joint theory-experiment study attributes the upconversion photoluminescen…
Detecting Atomic Scale Surface Defects in STM of TMDs with Ensemble Deep Learning
Darian Smalley, Stephanie D. Lough, Luke Holtzman +6
Atomic-scale defect detection is shown in scanning tunneling microscopy images of single crystal WSe2 using an ensemble of U-Net-like convolutional neural networks. Standard deep l…
Two-step flux synthesis of ultrapure transition metal dichalcogenides
Song Liu, Yang Liu, Luke Nemetz Holtzman +10
Here, we describe synthesis of TMD crystals using a two-step flux growth method that eliminates a major potential source of contamination. Detailed characterization of TMDs grown b…
