Abstract We study q ¯ $$ \overline{q} $$ q-hybrid mixing for the light vector mesons and q ¯ $$ \overline{q} $$ q-glueball mixing for the light scalar mesons in Monte-Carlo based QCD Laplace sum rules. By calculating the two-point correlation funct

Self-assembled GaAs nanowires were grown by molecular beam epitaxy (MBE) on un-pretreated Si(111) substrates under different As4/Ga flux ratios (V/III ratios). It has been found that the fraction of vertical wires would be nearly 100% when the As4/Ga

InAs/GaAs quantum dots (QDs) grown on a GaAs (001) substrate were studied by photoluminescence spectroscopy. Both C2v and D3h QDs with featured XX11, X11+, and XX21+ spectra have been found. A local defect field tunes the dominant exciton from X+ to
