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…
Photoconductive Effects in Single Crystals of BaZrS
Boyang Zhao, Huandong Chen, Ragib Ahsan +11
Chalcogenide perovskites, such as BaZrS, are emerging semiconductors with potential for high photovoltaic power conversion efficiency. The role of defects in the efficiency of…
Scaling Nanoribbon Transistors with Monolayer Transition Metal Dichalcogenides
Tara Peña, Anton E. O. Persson, Andrey Krayev +13
Nanoscale transistors require aggressive reduction of all channel dimensions: length, width, and thickness. While monolayer two-dimensional semiconductors (2DS) offer ultimate thic…
Beyond Seamless: Unexpected Defective Merging in Single-Orientation Graphene
Zhien Wang, Jiangtao Wang, Diego Exposito +7
Single-orientation stitching of graphene has emerged as the predominant method for growth of large-area, high-quality graphene films. Particularly noteworthy is graphene grown on s…
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…
Highly tunable room-temperature plexcitons in monolayer WSe2 /gap-plasmon nanocavities
Thomas P. Darlington, Mahfujur Rahaman, Kevin W. C. Kwock +16
The advancement of quantum photonic technologies relies on the ability to precisely control the degrees of freedom of optically active states. Here, we realize real-time, room-temp…
