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…
