The electronic states of nano-structures are studied in the framework of effective-mass envelope-function theory using the plane wave basis. The barrier width a
We apply perturbative QCD to the radiative decays of charmonia J/ψ and XcJ into light mesons. We perform a complete numerical calculation for the quark-gluon l
The interaction between small vacancy clusters and twin boundaries in copper is studied by using many-body potential developed by Ackland et al. for fcc metals.
Optoelectronic properties of the oxadiazole-functionalized iridium complex-doped polymer light-emitting devices (PLEDs) are demonstrated with two different poly
We report on the optical planar waveguide formation in KTiOPO4 crystals by single or double oxygen ion implantation at energies of 2.4-3.0MeV and doses of 1015
The insertion layer of TiO2 between polymer-fullerene blend and LiF/Al electrode is used to enhance the shortcircuit current Iso and fill factor (FF). The solar
We study the epidemic spreading of the susceptible-infected-susceptible model on small-world networks with modular structure.It is found that the epidemic thres
