Metallic vs. Semiconducting Properties of Quasi-One-Dimensional Tantalum Selenide van der Waals Nanoribbons
Fariborz Kargar, Andrey Krayev, Michelle Wurch +7
We conducted a tip-enhanced Raman scattering spectroscopy (TERS) and photoluminescence (PL) study of quasi-1D TaSe3 nanoribbons exfoliated onto gold substrates. At a selenium defic…
Nanoscale Optical Imaging of 2D Semiconductor Stacking Orders by Exciton-Enhanced Second Harmonic Generation
Kaiyuan Yao, Shuai Zhang, Emanuil Yanev +9
Second harmonic generation (SHG) is a nonlinear optical response arising exclusively from broken inversion symmetry in the electric-dipole limit. Recently, SHG has attracted widesp…
Nanoscale Raman Characterization of a 2D Semiconductor Lateral Heterostructure Interface
Sourav Garg, J. Pierce Fix, Andrey V. Krayev +7
The nature of the interface in lateral heterostructures of 2D monolayer semiconductors including its composition, size, and heterogeneity critically impacts the functionalities it…
Spatiotemporal Imaging of Thickness-Induced Band Bending Junctions
Joeson Wong, Artur R. Davoyan, Bolin Liao +8
Van der Waals materials exhibit naturally passivated surfaces and can form versatile heterostructures, enabling observation of carrier transport mechanisms not seen in three-dimens…
