The transmission and dielectric spectra of ferroelectric STO/PT superlattice on Si substrate under simultaneous external optical and electric field were investigated and compared at room temperature. Results found that when with an optical field, the electric field realized an effective modulation on the transmission, which displayed a diode property. In addition, a comprehensive model combined...

[1] The comment by Rapp and Lübken [2003b] (hereinafter referred to as R&L) on our paper [Belova et al., 2003] (hereinafter referred to as BCKR) contains two major points. The first pertains to an extension to their own work [Rapp and Lübken, 2000] reducing the relevant time constant. The second relates to the correctness of using the electron Debye length in formula (1) of BCKR for plasma wher...

The structural, elastic, and electronic properties of ReN2 are investigated by first-principles calculations with density functional theory. The obtained orthorhombic Pbcn structure is energetically the most stable structure at ambient pressure. ReN2 is a metallic, superincompressible solid and presents a rather elastic anisotropy. The estimated Debye temperature and hardness are 735 K and 17.1...

The nuclear spin-lattice relaxation of A1 N M R in AlBr 3 has been examined from 25 to 320 K. The result is analyzed using a theory of the R a m a n process based on covalency. A Debye temperature of 118 K is obtained together with a covalency larger than that obtained f rom the relaxation in the 8 1 Br N Q R .

The dielectric with index of refraction n is inserted in the Planck blackbody. The spectral formula for photons in such dielectric medium and the equation for the temperature of photons is derived. The new equation is solved for the constant index of refraction. The photon flow initiates the osmotic pressure of he Debye phonons. The dielectric crystal surface works as the osmotic membrane with ...

A tight-binding model is fit to first-principles calculations for copper that include structures distorted according to elastic constants and highsymmetry phonon modes. With the resulting model the first-principlesbased phonon dispersion and the free energy are calculated in the quasiharmonic approximation. The resulting thermal expansion, the temperatureand volume-dependence of the elastic con...

The aim of this work is to characterize the dielectric properties of amorphous dendritic macromolecules as a function of architectural complexity. By combining thermostimulated currents and dynamic dielectric spectroscopy, the dielectric permittivity has been obtained as a function of temperature, in a very broad frequency range (10–10 Hz). Generations g = 0 to g = 2 were investigated. The mole...
