Field Effect Optoelectronic Modulation of Quantum-Confined Carriers in Black Phosphorus
William S. Whitney, Michelle C. Sherrott, Deep Jariwala +4
We report measurements of the infrared optical response of thin black phosphorus under field-effect modulation. We interpret the observed spectral changes as a combination of an am…
Gate-dependent Pseudospin Mixing in Graphene/Boron Nitride Moire Superlattices
Zhiwen Shi, Chenhao Jin, Wei Yang +13
Electrons in graphene are described by relativistic Dirac-Weyl spinors with a two-component pseudospin1-12. The unique pseudospin structure of Dirac electrons leads to emerging phe…
Strong interlayer coupling in van der Waals heterostructures built from single-layer chalcogenides
Hui Fang, Corsin Battaglia, Carlo Carraro +16
Semiconductor heterostructures are the fundamental platform for many important device applications such as lasers, light-emitting diodes, solar cells and high-electron-mobility tra…
Drude Conductivity of Dirac Fermions in Graphene
Jason Horng, Chi-Fan Chen, Baisong Geng +9
Electrons moving in graphene behave as massless Dirac fermions, and they exhibit fascinating low-frequency electrical transport phenomena. Their dynamic response, however, is littl…
Device fabrication and transport measurements of FinFETs built with Si SOI wafers towards donor qubits in silicon
CC Lo, A Persaud, S Dhuey +6
We report fabrication of transistors in a FinFET geometry using isotopically purified silicon-28 -on-insulator (28-SOI) substrates. Donor electron spin coherence in natural silicon…
