Magneto-transport Subbands Spectroscopy in InAs Nanowires
Florian Vigneau, Vladimir Prudkovkiy, Ivan Duchemin +6
We report on magneto-transport measurements in InAs nanowires under large magnetic field (up to 55T), providing a direct spectroscopy of the 1D electronic band structure. Large mod…
Noise studies of magnetization dynamics in dilute magnetic semiconductor heterostructures
V. Tripathi, Kusum Dhochak, B. A. Aronzon +3
We study theoretically and experimentally the frequency and temperature dependence of resistivity noise in semiconductor heterostructures delta-doped by Mn. The resistivity noise i…
Integer Quantum Hall Effect in Trilayer Graphene
A. Kumar, W. Escoffier, J. M. Poumirol +7
The Integer Quantum Hall Effect (IQHE) is a distinctive phase of two-dimensional electronic systems subjected to a perpendicular magnetic field. Thus far, the IQHE has been observe…
Unveiling the Landau Levels Structure of Graphene Nanoribbons
Rebeca Ribeiro, Jean-Marie Poumirol, Alessandro Cresti +5
Magnetotransport measurements are performed in ultraclean (lithographically patterned) graphene nanoribbons down to 70 nm. At high magnetic fields, a fragmentation of the electroni…
Charge inhomogeneities and transport in semiconductor heterostructures with a manganese -layer
Vikram Tripathi, Kusum Dhochak, B. A. Aronzon +5
We study experimentally and theoretically the effects of disorder, nonlinear screening, and magnetism in semiconductor heterostructures containing a -layer of Mn, where the char…
High magnetic field induced charge density waves and sign reversal of the Hall coefficient in graphite
Amit Kumar, Jean-Marie Poumirol, Walter Escoffier +3
We report on the investigation of magnetic field induced charge density wave and Hall coefficient sign reversal in a quasi-two dimensional electronic system of highly oriented pyro…
