Interplay between the electrical transport properties of GeMn thin films and Ge substrates
N. Sircar, S. Ahlers, C. Majer +2
We present evidence that electrical transport studies of epitaxial p-type GeMn thin films fabricated on high resistivity Ge substrates are severely influenced by parallel conductio…
All-electric detectors of the polarization state of terahertz laser radiation (extended version)
S. D. Ganichev, W. Weber, J. Kiermaier +7
Two types of room temperature detectors of terahertz laser radiation have been developed which allow in an all-electric manner to determine the plane of polarization of linearly po…
Subnanosecond Ellipticity Detector for Laser Radiation (second version, extended)
S. D. Ganichev, W. Weber, J. Kiermaier +7
Two types of room temperature detectors of terahertz laser radiation have been developed which allow in an all-electric manner to determine the plane of polarization of linearly po…
Clustering in a precipitate free GeMn magnetic semiconductor
D. Bougeard, S. Ahlers, A. Trampert +2
We present the first study relating structural parameters of precipitate free Ge0.95Mn0.05 films to magnetisation data. Nanometer sized clusters - areas with increased Mn content o…
Magnetic and structural properties of GeMn films: precipitation of intermetallic nanomagnets
S. Ahlers, D. Bougeard, N. Sircar +4
We present a comprehensive study relating the nanostructure of Ge_0.95Mn_0.05 films to their magnetic properties. The formation of ferromagnetic nanometer sized inclusions in a def…
