High mobility ambipolar MoS2 field-effect transistors: Substrate and dielectric effects
TL;DR: In this paper, the authors fabricate MoS2 field effect transistors on both SiO2 and polymethyl methacrylate (PMMA) dielectrics and measure charge carrier mobility in a four-probe configuration.

TL;DR: In this paper, the bulk electrical conductivity of most topological insulators is relatively high, masking many of the important characteristics of its protected, surface conducting states, and counter-doping reduces the bulk conductivities of Bi2Se3 significantly, allowing these surface states and their properties to be clearly identified.
Journal ArticleDOI
Quantum control and process tomography of a semiconductor quantum dot hybrid qubit
Dohun Kim,Zhan Shi,Christie Simmons,D. R. Ward,Jonathan Prance,Teck Seng Koh,John King Gamble,Donald E. Savage,Max G. Lagally,Mark Friesen,Susan Coppersmith,Mark A. Eriksson +11 more
TL;DR: This work demonstrates a qubit that is a hybrid of spin and charge, requiring neither nuclear-state preparation nor micromagnets, and enables fast rotations about two axes of the Bloch sphere.
Journal ArticleDOI
Approaching the limits of transparency and conductivity in graphitic materials through lithium intercalation
Wenzhong Bao,Jiayu Wan,Xiaogang Han,Xinghan Cai,Hongli Zhu,Dohun Kim,Dakang Ma,Yunlu Xu,Jeremy N. Munday,H. Dennis Drew,Michael S. Fuhrer,Michael S. Fuhrer,Liangbing Hu +12 more
TL;DR: In situ optical transmittance spectra and electrical transport properties of ultrathin graphite (3-60 graphene layers) simultaneously during electrochemical lithiation/delithiation and on intercalation are measured, observing an increase of both opticalTransmission and electrical conductivity, strikingly different from other materials.
