Extreme ultraviolet emission from dense plasmas generated with sub-10-fs laser pulses
J. Osterholz, F. Brandl, M. Cerchez +7
The extreme ultraviolet (XUV) emission from dense plasmas generated with sub-10-fs laser pulses with varying peak intensities up to 3*10^16 W/cm^2 is investigated for different tar…
Magnetic barrier induced conductance fluctuations in quantum wires
S. Hugger, Hengyi Xu, A. Tarasov +5
Quasi-ballistic semiconductor quantum wires are exposed to localized perpendicular magnetic fields, also known as magnetic barriers. Pronounced, reproducible conductance fluctuatio…
Absorption of Ultrashort Laser Pulses in Strongly Overdense Targets
M. Cerchez, R. Jung, J. Osterholz +4
We report on the first absorption experiments of sub-10 fs high-contrast Ti:Sa laser pulses incident on solid targets. The very good contrast of the laser pulse assures the formati…
Influence of magnetic field offsets on the resistance of magnetic barriers in two-dimensional electron gases
S. Hugger, M. Cerchez, H. Xu +1
Magnetic barriers in two-dimensional electron gases are shifted in B space by homogeneous, perpendicular magnetic fields. The magnetoresistance across the barrier shows a character…
Effect of edge transmission and elastic scattering on the resistance of magnetic barriers
M. Cerchez, S. Hugger, T. Heinzel +1
Strong magnetic barriers are defined in two-dimensional electron gases by magnetizing dysprosium ferromagnetic platelets on top of a Ga[Al]As heterostructure. A small resistance ac…
