Electron spin resonance driven photogalvanic effect in graphene-based structures
C. Bray, I. Yahniuk, L. E. Golub +13
We report an electron-spin-resonance-driven linear photogalvanic effect (LPGE) in unbiased monolayer graphene and WSe_2/graphene heterostructures. Under linearly polarized 45--75 G…
Nonlinear Terahertz Electroluminescence from Dirac Landau Polaritons
B. Benhamou-Bui, C. Consejo, S. S. Krishtopenko +15
We report Dirac Landau polaritons observed by terahertz (THz) magnetoreflectivity spectroscopy, demonstrating strong coupling between cyclotron transitions of two-dimensional (2D)…
Spin-dependent photovoltage in graphene/MoS2-based field-effect transistors
K. Dinar, J. Delgado-Notario, C. Bray +14
It has recently been shown that Terahertz sensors can effectively detect the spin resonances of Dirac fermions in graphene. The associated photovoltaic measurement technique allows…
Multi-probe analysis to separate edge currents from bulk currents in quantum spin Hall insulators and to analyze their temperature dependence
S. Benlenqwanssa, S. S. Krishtopenko, M. Meyer +13
We present a multi-probe transport analysis that effectively separates bulk and edge currents in large Hall bar devices with standard geometries. Applied to transport measurements…
Magnetophotogalvanic Effects Driven by Terahertz Radiation in CdHgTe Crystals with Kane Fermions
M. D. Moldavskaya, L. E. Golub, V. V. Bel'kov +10
We report on the observation and comprehensive study of the terahertz radiation induced magneto-photogalvanic effect (MPGE) in bulk CdHgTe crystals hosting Kane fermions. The MPGE…
Gate tunable terahertz cyclotron emission from two-dimensional Dirac fermions
B. Benhamou-Bui, C. Consejo, S. S. Krishtopenko +15
Two-dimensional Dirac fermions in HgTe quantum wells close to the topological phase transition can generate significant cyclotron emission that is magnetic field tunable in the Ter…
