Electronic transport in BN-encasulated graphene limited by remote phonon scattering
Khalid Dinar, Francesco Macheda, Alberto Guandalini +6
We study the impact of BN's phonons on the electrical resistivity of hBN-encapsulated graphene. While encapsulation yields high-mobility devices, the surrounding BN itself introduc…
Many-particle hybridization of optical transitions from zero-mode Landau levels in HgTe quantum wells
S. Ruffenach, S. S. Krishtopenko, A. V. Ikonnikov +6
We present far-infrared magnetospectroscopy measurements of a HgTe quantum well in the inverted band structure regime over the temperature range of 2 to 60 K. The particularly low…
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…
Terahertz and gigahertz magneto-ratchets in graphene-based 2D metamaterials
Marcel Hild, Erwin Mönch, Leonid E. Golub +15
We report on the observation and study of the magneto-ratchet effect in a graphene-based two-dimensional metamaterial formed by a graphite gate that is placed below a graphene mono…
