چکیده
We report the far-infrared properties of superconducting ab plane-oriented YBa2Cu3O7-d films in magnetic fields of up to 27 T. The applications of magnetic field (with H perpendicular to the ab plane and with unpolarized light) at low temperature produces no discernible field dependence. This observation differs from other previous far-infrared measurements in this temperature range. Only at fields and temperatures where the dc resistance is not zero – on account of dissipative flux motion – is a field-induced effect observed. q 1998 Elsevier Science Ltd. All rights reserved.

We demonstrate that in low temperature semiconductor-like regions the electrical resistance of single-walled carbon nanotube mats is highly nonlinear with a temperature-dependent threshold ®eld for the onset of nonohmic conduction. The modest applied electric ®eld completely suppresses the upturn in resistance and recovers metallic behavior over the entire temperature range 2.2 K , T , 300 K. T...

Using a scanning tunneling microscope in a large number of approach and retraction experiments, quantized conductance is observed for the first time in gallium. We compare the conductance quantization at temperatures between 300 and 4.2 K, just slightly below and far below the bulk melting point of gallium. We find that the conductance is significantly dependent on temperature and find a modera...

A general theoretical approach to double photoemission from solid surfaces is formulated in terms of two-electron Green functions and two-electron states. By incorporating the screened Coulomb interaction between the two outgoing electrons in a dynamically screened effective one-electron potential, approximate expressions for the two-photoelectron current are derived, which essentially consist ...

Dielectric properties, including linear (refractive index) and second-order nonlinear optical responses, of LiNb12yTayO3-type mixed single crystals with y 0:00; 0.81, 0.92, 0.97, and 1.00 have been quantitatively studied. Based on the corresponding crystal compositions, the chemical bond method was applied. The results show that the dielectric susceptibilities at 1.064 mm decrease remarkably ...

We use dynamical local-®eld corrections to study the plasmon dispersion and damping in double-layer electron systems. The wave vector and frequency-dependent local-®elds describing the exchange-correlation effects are obtained within the quantum version of self-consistent ®eld approach. The calculated plasmon dispersions are modi®ed by the dynamic local-®elds at intermediate wave vectors (i.e. ...
