The aim of this work was to study the spin effects in non-magnetic asymmetric n-type resonant tunneling diodes (RTD). For this purpose, we have used transport and polarization resolved magneto-photoluminescence measurement ...

In this thesis, we have investigated the optical and transport properties of a p-i-n GaAs-AlAs resonant tunneling diode (RTD). The possibility of controlling and significantly varying the density of carriers accumulated ...

In classical Physics, the motion of an electrically charged particle is affected only by the presence of a magnetic field if the particle enters a region of space in which the field is present. Meanwhile, in quantum Physics, ...

In this work, it was investigated the optical and magneto-optical properties of In- GaAsN/GaAs and InGaAs/GaAs double quantum wells. It was performed a systematic experimental study of photoluminescence (PL) as a function ...

In the present thesis, we realize a computational modeling of semiconductor structures based on multiple quantum wells with filter barriers and on quantum wells with semiconductor diluted magnetic layers. We numerically ...

In this work, we studied the influence of surface charges on the properties (especially electronic transport) of semiconductor nanowires and nanobelts via computer simulations and also they were compared to experimental ...

Resonant Tunneling Diodes (RTDs) are semiconductor devices usually composed of two barrier structures embedding a single quantum well (QW) and highly doped layers in its extremities. Under an applied bias voltage, the ...

Zinc phosphide Zn3P2 nanowires with excellent crystalline quality were grown using the Vapor-Liquid-Solid (VLS) method with gold nanoparticles as catalysts. Single nanowire based devices were fabricated with ohmic nickel ...

Solar cells composed of semiconductor materials with gap energies and different structures, commonly known as Multijunction, have been the record holders for efficiency in converting solar to electric energy in recent ...

Abstract In this work, germanium nanowires' based devices were studied and developed and the influence of natural disorder on the electronic properties of these structures was also investigated. Parameters related to the ...
