Magnetoresistance oscillations in multilayer systems - triple quantum wells
S. Wiedmann, N. C. Mamani, G. M. Gusev +3
Magnetoresistance of two-dimensional electron systems with several occupied subbands oscillates owing to periodic modulation of the probability of intersubband transitions by the q…
Picosecond charge variation of quantum dots under pulsed excitation
Tomasz Kazimierczuk, Mateusz Goryca, Maciej Koperski +5
We present a spectroscopic study of excitation dynamics in self assembled CdTe/ZnTe quantum dots. Insight into details of kinetics is obtained from the time resolved micro-photolum…
Measurement of the infrared transmission through a single doped GaAs quantum well in an external magnetic field: Evidence for polaron effects
C. Faugeras, M. Orlita, S. Deutschlander +5
Precise absolute far-infra-red magneto-transmission experiments have been performed in magnetic fields up to 33 T on a series of single GaAs quantum wells doped at different levels…
How Graphene-like is Epitaxial Graphene? \\Quantum Oscillations and Quantum Hall Effect
Johannes Jobst, Daniel Waldmann, Florian Speck +4
We investigate the transport properties of high-quality single-layer graphene, epitaxially grown on a 6H-SiC(0001) substrate. We have measured transport properties, in particular c…
High order fractional microwave induced resistance oscillations in 2D systems
S. Wiedmann, G. M. Gusev, O. E. Raichev +2
We report on the observation of microwave-induced resistance oscillations associated with the fractional ratio n/m of the microwave irradiation frequency to the cyclotron frequency…
Plateau insulator transition in graphene
M. Amado, E. Diez, D. López-Romero +5
The quantum Hall effect in a single-layer graphene sample is studied in strong magnetic fields up to 28 T. Our measurements reveal the existence of a metal- insulator transition fr…
Microwave magnetoplasmon absorption by a 2DEG stripe
O. M. Fedorych, S. Moreau, M. Potemski +3
Microwave absorption by a high mobility 2DEG has been investigated experimentally using sensitive Electron Paramagnetic Resonance cavity technique. It is found that MW absorption s…
Slowing hot carrier relaxation in graphene using a magnetic field
P. Plochocka, P. Kossacki, A. Golnik +4
A degenerate pump--probe technique is used to investigate the non equilibrium carrier dynamics in multi--layer graphene. Two distinctly different dynamics of the carrier relaxation…
Possible Fractional Quantum Hall Effect in Graphite
Y. Kopelevich, B. Raquet, M. Goiran +6
Measurements of basal plane longitudinal rho_b(B) and Hall rho_H(B) resistivities were performed on highly oriented pyrolytic graphite (HOPG) samples in pulsed magnetic field up to…
How perfect can graphene be?
P. Neugebauer, M. Orlita, C. Faugeras +2
Fabrication of graphene structures has triggered vast research efforts focused on the properties of two-dimensional systems with massless Dirac fermions. Nevertheless, further prog…
A consistent interpretation of the low temperature magneto-transport in graphite using the Slonczewski--Weiss--McClure 3D band structure calculations
J. M. Schneider, M. Orlita, M. Potemski +1
Magnetotransport of natural graphite and highly oriented pyrolytic graphite (HOPG) has been measured at mK temperatures. Quantum oscillations for both electron and hole carriers ar…
Graphite from the viewpoint of Landau level spectroscopy: An effective graphene bilayer and monolayer
M. Orlita, C. Faugeras, J. M. Schneider +3
We describe an infrared transmission study of a thin layer of bulk graphite in magnetic fields up to B = 34 T. Two series of absorption lines whose energy scales as sqrtB and B are…
Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
K. -J. Friedland, A. Siddiki, R. Hey +3
The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. The novel topology leads to a spatially varying filling factor…
Optical absorption to probe the quantum Hall ferromagnet at filling factor
P. Plochocka, J. M. Schneider, D. K. Maude +7
Optical absorption measurements are used to probe the spin polarization in the integer and fractional quantum Hall effect regimes. The system is fully spin polarized only at fillin…
