Intrinsic Phonon Bands in High-Quality Monolayer T' Molybdenum Ditelluride
Shao-Yu Chen, Carl H. Naylor, Thomas Goldstein +2
The topologically nontrivial and chemically functional distorted octahedral (T') transition metal dichalcogenides (TMDCs) are a type of layered semimetal that has attracted signifi…
Activation of new Raman modes by inversion symmetry breaking in type II Weyl semimetal candidate T'-MoTe2
Shao-Yu Chen, Thomas Goldstein, Dhandapani Venkataraman +2
We synthesized distorted octahedral(T') molybdenum ditelluride (MoTe2) and investigated its vibrational properties with Raman spectroscopy, density functional theory and symmetry a…
Antenna enhanced graphene THz emitter and detector
Jiayue Tong, Martin Muthee, Shao-Yu Chen +2
Recent intense electrical and optical studies of graphene have pushed the material to the forefront of optoelectronic research. Of particular interest is the few terahertz (THz) fr…
Optical properties of bulk semiconductors and graphene/boron-nitride: The Bethe-Salpeter equation with derivative discontinuity-corrected DFT energies
Jun Yan, Karsten W. Jacobsen, Kristian S. Thygesen
We present an efficient implementation of the Bethe-Salpeter equation (BSE) for optical properties of materials in the projector augmented wave method GPAW. Single-particle energie…
Raman Spectroscopy of magneto-phonon resonances in Graphene and Graphite
Sarah Goler, Jun Yan, Vittorio Pellegrini +1
The magneto-phonon resonance or MPR occurs in semiconductor materials when the energy spacing between Landau levels is continuously tuned to cross the energy of an optical phonon m…
Dual-gated bilayer graphene hot electron bolometer
J. Yan, M. -H. Kim, J. A. Elle +5
Detection of infrared light is central to diverse applications in security, medicine, astronomy, materials science, and biology. Often different materials and detection mechanisms…
Dispersive and Covalent Interactions Between Graphene and Metal Surfaces from the Random Phase Approximation
T. Olsen, J. Yan, J. J. Mortensen +1
We calculate the potential energy surfaces for graphene adsorbed on Cu(111), Ni(111), and Co(0001) using density functional theory and the Random Phase Approximation (RPA). For the…
Correlated charged impurity scattering in graphene
Jun Yan, Michael S. Fuhrer
Understanding disorder in graphene is essential for electronic applications; in contrast to conventional materials, the extraordinarily low electron-phonon scattering1, 2 in graphe…
Rapid collapse of spin waves in non-uniform phases of the second Landau level
Trevor D. Rhone, Jun Yan, Yann Gallais +3
The spin degree of freedom in quantum phases of the second Landau level is probed by resonant light scattering. The long wavelength spin wave, which monitors the degree of spin pol…
Observation of magneto-phonon resonance of Dirac fermions in graphite
J. Yan, S. Goler, T. D. Rhone +5
Coherent coupling of Dirac fermion magneto-excitons with an optical phonon is observed in graphite as marked magnetic-field dependent splittings and anti-crossing behavior of the t…
