The growth and characterization of semiconductor nanowires systems have attracted increasing interest due to their potential technological application, like, photo-detectors, optoelectronic devices and their promising ...

In this work the ground and first excited states of the electron are calculated in interacting one-dimensional, two-dimensional lattices and multilayers of cylindrical quantum dots containing at the most an electron and ...

In this work, we have studied the transport and optical properties of GaAs = AlGaAs resonant tunneling diodes with Si delta-doping at the center of the quantum well. We have studied magneto-transport and polarized resolved ...

Diamond films grown by both hot filament (HFCVD) and microwave-plasma (MW-CVD) assisted chemical vapor deposition were investigated. Raman spectroscopy, scan- ning electron microscopy and X-ray di¤raction were employed ...

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 ...

Férmions fortemente interagentes estão entre os sistemas físicos mais estudados atualmente e são considerados responsáveis por fenômenos importantes, como por exemplo, supercondutividade a altas temperaturas (em cupratos) ...
