Single exciton trapping in an electrostatically defined 2D semiconductor quantum dot
Daniel N. Shanks, Fateme Mahdikhanysarvejahany, Michael R. Koehler +5
Interlayer excitons (IXs) in 2D semiconductors have long lifetimes and spin-valley coupled physics, with a long-standing goal of single exciton trapping for valleytronic applicatio…
Interlayer Exciton Diode and Transistor
Daniel N. Shanks, Fateme Mahdikhanysarvejahany, Trevor G. Stanfill +6
Controlling the flow of charge neutral interlayer exciton (IX) quasiparticles can potentially lead to low loss excitonic circuits. Here, we report unidirectional transport of IXs a…
Steady-state nonlinear optical response of excitons in monolayer MoSe
Muhed S. Rana, Joshua R. Hendrickson, Christopher E. Stevens +7
Monolayer transition metal dichalcogenide (TMD) semiconductors such as MoSe host strongly bound excitons which are known to exhibit a strong resonant third-order nonlinear resp…
Nanoscale trapping of interlayer excitons in a 2D semiconductor heterostructure
Daniel N. Shanks, Fateme Mahdikhanysarvejahany, Christine Muccianti +8
For quantum technologies based on single excitons and spins, the deterministic placement and control of a single exciton is a long-standing goal. MoSe2-WSe2 heterostructures host s…
Low-Temperature 2D/2D Ohmic Contacts in WSe Field-Effect Transistors as a Platform for the 2D Metal-Insulator Transition
L. J. Stanley, Hsun-Jen Chuang, Zhixian Zhou +4
We report the fabrication of hexagonal-boron-nitride (hBN) encapsulated multi-terminal WSe Hall bars with 2D/2D low-temperature Ohmic contacts as a platform for investigating t…
Low-Resistance 2D/2D Ohmic Contacts: A Universal Approach to High-Performance WSe2, MoS2, and MoSe2 Transistors
Hsun-Jen Chuang, Bhim Chamlagain, Michael Koehler +5
We report a new strategy for fabricating 2D/2D low-resistance ohmic contacts for a variety of transition metal dichalcogenides (TMDs) using van der Waals assembly of substitutional…
