Protective Molecular Passivation of Black Phosphorous
Vlada Artel, Qiushi Guo, Hagai Cohen +4
Black phosphorous (BP) is one of the most interesting layered materials, bearing promising potential for emerging electronic and optoelectronic device technologies. The crystalline…
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…
Realizing Giant Magneto-Optical Effects in 3D Topological Insulators Without Magnetic Fields
Moti Fridman, Vlada Artel, Anna Peled +3
Topological insulators display unusual light-matter interactions due to the helical nature of surface electronic states. We study the near-field interaction of light propagating in…
Raman scattering and anomalous Stokes anti-Stokes ratio in MoTe2 atomic layers
Thomas Goldstein, Shao-Yu Chen, Di Xiao +2
Stokes and anti-Stokes Raman scattering are performed on atomic layers of hexagonal molybdenum ditelluride (MoTe2), a prototypical transition metal dichalcogenide (TMDC) semiconduc…
Inversion-symmetry-breaking-activated shear Raman bands in -MoTe
Shao-Yu Chen, Thomas Goldstein, Ashwin Ramasubramaniam +1
Type-II Weyl fermion nodes, located at the touching points between electron and hole pockets, have been recently predicted to occur in distorted octahedral () transition metal…
