We theoretically investigate properties of the ground state of a closed dot-ring system with a magnetic flux in theKondo regime by means of a tight-banding Ande
The C1s and O 1s electrons in polymethyl methacrylate etched by different incident laser intensities are analysed by x-ray photoelectron spectroscopy. The resul
Optical conductivity of anisotropic double-parabolic quantum dots is investigated with the memory-function approach, and the analytic expression for the optical
A new method is introduced to generate a hollow beam inside a cavity. Using a matrix eigenvalue method, the laser resonator with optical diffraction elements is
We study the transport efficiency for x-rays of single-wall carbon nanotubes (SWCNTs) in theory. Three effects,i.e. refraction, absorption and x-ray tunneling l
We perform the micro-photoluminescence measurement at low temperatures and a scanning optical mapping with high spatial resolution of a single V-grooved GaAs qu
