Geometric and chemical components of the giant piezoresistance in silicon nanowires
M. McClarty, N. Jegenyes, M. Gaudet +5
A wide variety of apparently contradictory piezoresistance (PZR) behaviors have been reported in p-type silicon nanowires (SiNW), from the usual positive bulk effect to anomalous (…
The effect of Pauli blockade on spin-dependent diffusion in a degenerate electron gas
F. Cadiz, D. Paget, A. C. H. Rowe
Spin-polarized transport of photo-electrons in bulk, p-type GaAs is investigated in the Pauli blockade regime. In contrast to usual spin diffusion processes in which the spin polar…
Piezoresistance in Silicon and its nanostructures
A. C. H. Rowe
Piezoresistance is the change in the electrical resistance, or more specifically the resistivity, of a solid induced by an applied mechanical stress. The origin of this effect in b…
Spin dependent photoelectron tunnelling from GaAs into magnetic Cobalt
D. Vu, H. F. Jurca, F. Maroun +6
The spin dependence of the photoelectron tunnel current from free standing GaAs films into out-of- plane magnetized Cobalt films is demonstrated. The measured spin asymmetry (A) re…
Imaging charge and spin diffusion of minority carriers in GaAs
I. Favorskiy, D. Vu, E. Peytavit +3
Room temperature electronic diffusion is studied in 3 mum thick epitaxial p+ GaAs lift-off films using a novel circularly polarized photoluminescence microscope. The method is equi…
Geometrical dependence of decoherence by electronic interactions in a GaAs/GaAlAs square network
M. Ferrier, A. C. H. Rowe, S. Gueron +3
We investigate weak localization in metallic networks etched in a two dimensional electron gas between mK and mK when electron-electron (e-e) interaction is the domina…
