ABSTRACT We propose a spintronic magnetic field sensor, fashioned out of quantum wires, which may be capable of detecting very weak magnetic fields with a sensitivity of ∼ at a temperature of 4.2 K, and ∼ at room temperature. Such sensors have commercial applications in magnetometry, quantum computing, solid-state nuclear magnetic resonance, magneto-encephalography, and military applications in weapon detection.

    ABSTRACT: The authors present a theory to describe spin transport across a polymer sandwiched between magnetic contacts and propose organic spin devices based on this theory. It is found that even a weak magnetic field can significantly modify spin transport in polymers through spin precession. This sensitivity can be exploited to design ultrasensitive magnetometers and low-power magnetic-field-effect transistors. It is shown that, at room temperature, the organic magnetometers are capable of detecting sub-nanotesla magnetic fields, and the I-V characteristics of the magnetic-field-effect transistors can be strongly modified by magnetic fields of a few gauss with response times of a few nanoseconds.

    ABSTRACT: The authors summarise semiclassical modelling methods, including drift-diffusion, kinetic transport equation and Monte Carlo simulation approaches, utilised in studies of spin dynamics and transport in semiconductor structures. As a review of the work by the authors' group, several examples of applications of these modelling techniques are presented.

    ABSTRACT: Conductivity of In0.38Ga0.62As quantum wires grown on the (311)A plane of GaAs was studied using temperature dependent Hall effect. Detailed analysis of the scattering phenomena which control electron mobility along the wires indicates that the most significant scattering mechanism which limits electron mobility at low temperatures is scattering from interface roughness. This finding contributes to the general understanding of the potential to use self-assembled semiconductor quantum wires in the fabrication of thermoelectric devices where one-dimensionality and enhanced scattering at rough boundaries are important.
