Nonmonotonous classical magneto-conductivity of a two-dimensional electron gas in a disordered array of obstacles
N. H. Siboni, J. Schluck, K. Pierz +4
Magnetotransport measurements in combination with molecular dynamics (MD) simulations on two-dimensional disordered Lorentz gases in the classical regime are reported. In quantitat…
Investigation of a possible electronic phase separation in the magnetic semiconductors GaMnAs and GaMnP by means of fluctuation spectroscopy
Martin Lonsky, Jan Teschabai-Oglu, Klaus Pierz +6
We present systematic temperature-dependent resistance noise measurements on a series of ferromagnetic GaMnAs epitaxial thin films covering a large parameter space in…
Tailoring the SiC surface - a morphology study on the epitaxial growth of graphene and its buffer layer
Mattias Kruskopf, Klaus Pierz, Davood Momeni Pakdehi +4
We investigate the growth of the graphene buffer layer and the involved step bunching behavior of the silicon carbide substrate surface using atomic force microscopy. The formation…
Direct Comparison of Fractional and Integer Quantized Hall Resistance
Franz J. Ahlers, Martin Götz, Klaus Pierz
We present precision measurements of the fractional quantized Hall effect where the quantized resistance in the fractional quantum Hall state at filling factor 1/3 was…
