Energy spectrum of confined positively charged excitons in single quantum dots
M. R. Molas, A. Wojs, A. A. L. Nicolet +2
A theoretical model, which relates the binding energy of a positively charged exciton in a quantum dot with the confinement energy is presented. It is shown that the binding energy…
The excited spin-triplet state of a charged exciton in quantum dots
M. R. Molas, A. A. L. Nicolet, B. Pietka +2
We report on single-object spectroscopic studies of a characteristic set of three resonances which appear in GaAlAs/AlAs quantum dot structures. The experiments included the photol…
Quadexciton cascade and fine structure splitting of the triexciton in a single quantum dot
M. R. Molas, A. A. L. Nicolet, A. Babinski +1
We report the properties of emission lines associated with the cascaded recombination of a quadexciton in single GaAlAs/AlAs quantum dots, studied by means of polarization-resolved…
Multiple magneto-phonon resonances in graphene
D. M. Basko, P. Leszczynski, C. Faugeras +5
Our low-temperature magneto-Raman scattering measurements performed on graphene-like locations on the surface of bulk graphite reveal a new series of magneto-phonon resonances invo…
Insulating state in tetralayers reveals an even-odd interaction effect in multilayer graphene
Anya L. Grushina, Dong-Keun Ki, Mikito Koshino +5
The absence of an energy gap separating valence and conduction bands makes the low-energy electronic properties of graphene and its multi-layers sensitive to electron-electron inte…
Magnetic field tuning of exciton polaritons in a semiconductor microcavity
B. Pietka, D. Zygmunt, M. Krol +11
We detail the influence of a magnetic field on exciton-polaritons inside a semiconductor microcavity. Magnetic field can be used as a tuning parameter for exciton and photon resona…
A micro-magneto-Raman scattering study of graphene on a bulk graphite substrate
C. Faugeras, J. Binder, A. A. L. Nicolet +5
We report on a magneto-Raman scattering study of graphene flakes located on the surface of a bulk graphite substrate. By spatially mapping the Raman scattering response of the surf…
Electrical switch to the resonant magneto-phonon effect in graphene
P. Leszczynski, Z. Han, A. A. L. Nicolet +7
We report a comprehensive study of the tuning with electric fields of the resonant magneto-exciton optical phonon coupling in gated graphene. For magnetic fields around …
Excited exciton and biexciton localised states in a single quantum ring
H. D. Kim, K. Kyhm, R. A. Taylor +6
We observe excited exciton and biexciton states of localised excitons in an anisotropic quantum ring, where large polarisation asymmetry supports the presence of a crescent-like lo…
Probing the band structure of quadri-layer graphene with magneto-phonon resonance
C. Faugeras, P Kossacki, A. A. L. Nicolet +4
We show how the magneto-phonon resonance, particularly pronounced in sp2 carbon allotropes, can be used as a tool to probe the band structure of multilayer graphene specimens. Even…
Polarization resolved magneto-Raman scattering of graphene-like domains on natural graphite
M. Kuhne, C. Faugeras, P. Kossacki +4
The micro-Raman scattering response of a graphene-like location on the surface of bulk natural graphite is investigated both at $T=\unit{4.2}{K}$ and at room temperature in magneti…
Electronic excitations and electron-phonon coupling in bulk graphite through Raman scattering in high magnetic fields
P. Kossacki, C. Faugeras, M. Kühne +6
We use polarized magneto-Raman scattering to study purely electronic excitations and the electron-phonon coupling in bulk graphite. At a temperature of 4.2 K and in magnetic fields…
Magneto-Raman scattering of graphene on graphite: Electronic and phonon excitations
C. Faugeras, M. Amado, P. Kossacki +5
Magneto-Raman scattering experiments from the surface of graphite reveal novel features associated to purely electronic excitations which are observed in addition to phonon-mediate…
