Exciton Diamagnetic Shifts and Valley Zeeman Effects in Monolayer WS and MoS to 65 Tesla

Andreas V. Stier, Kathleen M. McCreary, Berend T. Jonker +2

We report circularly-polarized optical reflection spectroscopy of monolayer WS and MoS at low temperatures (4~K) and in high magnetic fields to 65~T. Both the A and the B e…

Observation of a Helical Luttinger-Liquid in InAs/GaSb Quantum Spin Hall Edges

Tingxin Li, Pengjie Wang, Hailong Fu +8

We report on the observation of a helical Luttinger-liquid in the edge of InAs/GaSb quantum spin Hall insulator, which shows characteristic suppression of conductance at low temper…

Gate-Tuned Spontaneous Exciton Insulator in Double-Quantum Wells

Lingjie Du, Wenkai Lou, Kai Chang +2

It was proposed that a dilute semimetal is unstable against the formation of an exciton insulator, however experimental confirmations have remained elusive. We investigate the orig…

Helical Quantum Edge Gears in 2D Topological Insulators

Yang-Zhi Chou, Alex Levchenko, Matthew S. Foster

We show that two-terminal transport can measure the Luttinger liquid (LL) parameter , in helical LLs at the edges of two dimensional topological insulators (TIs) with Rashba spi…

Enhancing Electron Coherence via Quantum Phonon Confinement in Atomically Thin Nb3SiTe6

J. Hu, X. Liu, C. L. Yue +14

The extraordinary properties of two dimensional (2D) materials, such as the extremely high carrier mobility in graphene and the large direct band gaps in transition metal dichalcog…

Hall and field-effect mobilities in few layered -WSe field-effect transistors

N. R. Pradhan, D. Rhodes, S. Memaran +9

Here, we present a temperature () dependent comparison between field-effect and Hall mobilities in field-effect transistors based on few-layered WSe exfoliated onto SiO.…
