Efficient Green Emission from Edge States in Graphene Perforated by Nitrogen Plasma Treatment
N N Kovaleva, D Chvostova, Z Potůček +10
Plasma functionalization of graphene is one of the facile ways to tune its doping level without the need for wet chemicals making graphene photoluminescent. Microscopic corrugation…
X-ray magnetic circular dichroism characterization of GaN/Ga1-xMnxN digital ferromagnetic heterostructure
J. I. Hwang, M. Kobayashi, G. S. Song +8
We have investigated the magnetic properties of a GaN/Ga1-xMnxN (x = 0.1) digital ferromagnetic heterostructure (DFH) showing ferromagnetic behavior using soft x-ray absorption spe…
Equations for filling factor estimation in opal matrix
S. M. Abrarov, T. W. Kim, T. W. Kang
We consider two equations for the filling factor estimation of infiltrated zinc oxide (ZnO) in silica (SiO_2) opal and gallium nitride in ZnO opal. The first equation is based on t…
Deep level emission of ZnO nanoparticles deposited inside UV opal
S. M. Abrarov, Sh. U. Yuldashev, T. W. Kim +2
The temperature-dependent photoluminescence (PL) spectra of zinc oxide (ZnO) nanocrystals deposited inside the ultraviolet (UV) opal were studied. ZnO was grown in the voids betwee…
Metastability from Photoluminescence of n-type GaN
C. S. Park, T. W. Kang
We measured the temperature dependence of photoluminescence involved with the metastability of unintentionally doped GaN. Reaction energy U of donor atom is 0.1eV and shallow donor…
