    Magnetocapacitance and Edge States

    The spatial distribution of edge states at quantum Hall (QH) plateaus has been studied both experimentally and theoretically. In the classical simple picture, the width of the edge states is expected to be of ...

    Characterization of Laterally Selected Si Doped Layer Formed in GaAs Using a Low-Energy FIB-MBE Combined System

    200 eV and 30 keV Si2+ FIB were implanted in an MBE-grown GaAs layer in a dose range of 1012 and 1013 cm-2. Successive overlayer regrowth of the GaAs cap layer and postannealing at 800 °C for 3 - 30 s was perform...

    Low Energy Ion Irradiation Effect on Electron Transport in Gaas/Algaas Heterostructures

    Effects of low energy ion beam induced damages on transport properties of a two-dimensional electron gas (2DEG) system in GaAs/AlGaAs heterostructures have been investigated. 1 keV Ar ions were irradiated on t...
