Intersubband Quantum Disc-in-Nanowire Photodetectors with Normal-incidence Response in the Long-wavelength Infrared
Mohammad Karimi, Magnus Heurlin, Steven Limpert +9
Semiconductor nanowires offer great potential for realizing broadband photodetectors that are compatible with silicon technology. However, the spectral range of such detectors has…
Enhanced sputtering and incorporation of Mn in implanted GaAs and ZnO nanowires
A. Johannes, S. Noack, W. Paschoal +8
We simulated and experimentally investigated the sputter yield of ZnO and GaAs nanowires, which were implanted with energetic Mn ions at room temperature. The resulting thinning of…
Tunneling Anisotropic Magnetoresistance in Co/AlOx/Au Tunnel Junctions
R. S. Liu, L. Michalak, C. M. Canali +2
We observe spin-valve-like effects in nano-scaled thermally evaporated Co/AlOx/Au tunnel junctions. The tunneling magnetoresistance is anisotropic and depends on the relative orien…
Large Magnetoresistance in Co/Ni/Co Ferromagnetic Single Electron Transistors
R. S. Liu, H. Pettersson, L. Michalak +3
We report on magnetotransport investigations of nano-scaled ferromagnetic Co/Ni/Co single electron transistors. As a result of reduced size, the devices exhibit single electron tra…
Probing Spin Accumulation in Ni/Au/Ni Single-Electron Transistors with Efficient Spin Injection and Detection Electrodes
R. S. Liu, H. Pettersson, L. Michalak +2
We have investigated spin accumulation in Ni/Au/Ni single-electron transistors assembled by atomic force microscopy. The fabrication technique is unique in that unconventional hybr…
