Optical properties of amorphous ZnO have been investigated at room temperature. It is demonstrated that the ultraviolet emission components due to the recombina
We study the effects of the energy band structure of conduction-electron on the transport properties of an interacting quantum dot system. By applying the noneq
The doping-induced spectral weight transfer is studied by using the d-p model and considering spatial fluctuations in the high-Tc cuprates. The results led by t
Monte Carlo simulations are used to study the three-dimensional Holstein model. The relationship between the band filling and the chemical potential is obtained
Er3+-doped strontium-lead-bismuth glasses for developing potential upconversion lasers have been fabricated and characterized. Under 975nm excitation, intense g
A large-scalable quantum computer model, whose qubits are represented by the subspace subtended by the ground state and the single exciton state on semiconducto
Si nanowires with different diameters are grown on catalyst coated Si substrates via a solid-liquid-solid mechanism. It is found that the thickness and type of
