By means of first-principles calculations within the density functional theory, we study the structural and optical properties of codoped ZnO nanowires and compare them with those of the bulk and film...
We present time-resolved emission experiments of semiconductor quantum dots in silicon 3D inverse-woodpile photonic band gap crystals. A systematic study is made of crystals with a range of pore radii...
We report first principles studies of the hypothetical compound Bi6Ti4O17, which is an alternate stacking of the ferroelectric Bi4Ti3O12. We find that this compound is ferroelectric, similar to Bi4Ti3...
We have investigated the magnetoconductance of semiconducting carbon nanotubes (CNTs) in pulsed, parallel magnetic elds up to 60 T, and report the direct observation of the predicted band-gap closur...
We have recently described a novel method for the construction of a solid-state optical frequency reference based on doping $^{229}$Th into high energy band-gap crystals. Since nuclear transitions ar...
We demonstrate the first guiding of cold atoms through a 88 mm long piece of photonic band gap fiber. The guiding potential is created by a far-off resonance dipole trap propagating inside the fiber w...
Based o n the non-symmetric transmission-line method, the b and gap structure of disordered chiral photonic c rystals (CPC) has b een inve stigated. T he influence of the c hiral parameters, the disor...
2001Vol.36No.4pp.477-482DOI: Coupled Band Gap Solitons in One-Dimensional Alternating Heisenberg Ferromagnetic Chains ZHU Shan-Hua1,2 and HUANG Guo-Xiang1 1 Key Laborato...
Numerical simulation based on FP-LAPW calculations is applied to study the lattice parameters, bulk modulus and band gap energy of zinc blende binaries AlN, GaN and InN under hydrostatic pressure. The...
Zinc selenide (ZnSe) thin films were deposited on glass substrate using the chemical bath deposition method at room temperature from aqueous solutions of zinc sulphate and sodium selenosulfate in whic...
Electronic properties of liquid water were investigated by sequential Monte Carlo/Quantum mechanics calculations. The density of states (DOS) and HOMO-LUMO gap (EG) of liquid water have been determine...
Improved techniques in semiconductor fabrication increased the interest in quantum wire structures, because of their opto-electronic device application possibilities. Many-body interactions among the ...
