Spin Structure of the Anisotropic Helimagnet CrNbS in a Magnetic Field
Benjamin J. Chapman, Alexander C. Bornstein, Nirmal J. Ghimire +2
In this letter we describe the ground-state magnetic structure of the highly anisotropic helimagnet CrNbS in a magnetic field. A Heisenberg spin model with Dyzaloshinki…
High Mobility WSe2 p- and n-Type Field Effect Transistors Contacted by Highly Doped Graphene for Low-Resistance Contacts
Hsun-Jen Chuang, Xuebin Tan, Nirmal Jeevi Ghimire +7
We report the fabrication of both n-type and p-type WSe2 field effect transistors with hexagonal boron nitride passivated channels and ionic-liquid (IL)-gated graphene contacts. Ou…
Mobility Improvement and Temperature Dependence in MoSe2 Field-Effect Transistors on Parylene-C Substrate
Bhim Chamlagain, Qing Li, Nirmal Jeevi Ghimire +9
We report low temperature scanning tunneling microscopy characterization of MoSe2 crystals, and the fabrication and electrical characterization of MoSe2 field-effect transistors on…
Probing excitonic states in ultraclean suspended two-dimensional semiconductors by photocurrent spectroscopy
A. R. Klots, A. K. M. Newaz, Bin Wang +12
The optical response of semiconducting monolayer transition-metal dichalcogenides (TMDCs) is dominated by strongly bound excitons that are stable even at room temperature. However,…
Observation of Long-Lived Interlayer Excitons in Monolayer MoSe2-WSe2 Heterostructures
Pasqual Rivera, John R. Schaibley, Aaron M. Jones +9
Two-dimensional (2D) materials, such as graphene1, boron nitride2, and transition metal dichalcogenides (TMDs)3-5, have sparked wide interest in both device physics and technologic…
Coherent Electronic Coupling in Atomically Thin MoSe2
Akshay Singh, Galan Moody, Sanfeng Wu +6
We report the first direct spectroscopic evidence for coherent electronic coupling between excitons and trions in atomically thin transition metal dichalcogenides, specifically mon…
