Magnetoresistance in a High Mobility Two-Dimensional Electron Gas
L. Bockhorn, P. Barthold, D. Schuh +2
In a high mobility two-dimensional electron gas (2DEG) in a GaAs/AlGaAs quantum well we observe a strong magnetoresistance. In lowering the electron density the magnetoresistance g…
Mobilities and Scattering Times in Decoupled Graphene Monolayers
H. Schmidt, T. Luedtke, P. Barthold +1
Folded single layer graphene forms a system of two decoupled monolayers being only a few Angstroms apart. Using magnetotransport measurements we investigate the electronic properti…
Tunable Graphene System with Two Decoupled Monolayers
H. Schmidt, T. Luedtke, P. Barthold +3
The use of two truly two-dimensional gapless semiconductors, monolayer and bilayer graphene, as current-carrying components in field-effect transistors (FET) gives access to new ty…
Nanomachining of multilayer graphene using an atomic force microscope
P. Barthold, T. Luedtke, R. J. Haug
An atomic force microscope is used to structure a film of multilayer graphene. The resistance of the sample was measured in-situ during nanomachining a narrow trench. We found a re…
Nanomachining of mesoscopic graphite
P. Barthold, T. Luedtke, R. J. Haug
An atomic force microscope is used to structure a film of multilayer graphene. The resistance of the sample was measured in-situ during nanomachining narrow trenches. We found a re…
Enhanced Shot Noise in Tunneling through a Stack of Coupled Quantum Dots
P. Barthold, F. Hohls, N. Maire +2
We have investigated the noise properties of the tunneling current through vertically coupled self-assembled InAs quantum dots. We observe super-Poissonian shot noise at low temper…
