Porous graphene and graphenylene nanotubes: Electronic structure and strain effects
(2017-12-01)
The unusual and unique mechanical and electronic properties of nanostructured carbon materials make them useful in the construction of nanodevices. We investigate a new class of structures, called porous nanotubes, which ...
Structural characterization and EXAFS wavelet analysis of Yb doped ZnO by wet chemistry route
(Elsevier Science Sa, 2015-02)
Lanthanide doped ZnO are interesting materials for optical and electrical applications. The wide band gap of this semiconductor makes it transparent in the visible range (Egap = 3.2 eV), allowing a sharp emission from intra ...
Spin-Induced Optical Second Harmonic Generation in the Centrosymmetric Magnetic Semiconductors EuTe and EuSe
(AMER PHYSICAL SOC, 2009)
Spectroscopy of the centrosymmetric magnetic semiconductors EuTe and EuSe reveals spin-induced optical second harmonic generation (SHG) in the band gap vicinity at 2.1-2.4 eV. The magnetic field and temperature dependence ...
Fractional quantum Hall effect in a dilute magnetic semiconductor
(American Physical Society, 2014-09)
We report the observation of the fractional quantum Hall effect in the lowest Landau level of a two-dimensional electron system (2DES), residing in the diluted magnetic semiconductor
Cd1−xMnxTe. The presence of magnetic ...
