Dielectric function of the two-dimensional electron liquid: An analytical fitting
Bulutay, C; Tomak, Mehmet (1996-03-15)
For electron-electron interactions in two-dimensional electronic systems the technique proposed by Singwi, Tosi, Land, and Sjolander (STLS) has been very promising. In this work, after showing the asymptotic behavior of the STLS local held correction we propose a simple expression for the local-held correction that contains two fitting parameters which are smoothly varying functions of the electronic density. The agreement of the fitting for the pair correlation function is remarkable. It further leads to a...

Dielectric and photo-dielectric properties of TlGaSeS crystals
Qasrawi, A. F.; Abu-Zaid, Samah F.; Ghanameh, Salam A.; Hasanlı, Nızamı (2014-05-01)
The room temperature, dark and photo-dielectric properties of the novel crystals TlGaSeS are investigated in the frequency, intensity and biasing voltage having ranges of similar to 1-120 MHz, 14-40 klux and 0-1 V, respectively. The crystals are observed to exhibit a dark high frequency effective dielectric constant value of similar to 10.65 x 10(3) with a quality factor of similar to 8.84 x 10(4) at similar to 120 MHz. The dielectric spectra showed sharp resonance-antiresonance peaks in the frequency range...
Dielectric functions and interband critical points of anisotropic chain structured TlSe single crystals
IŞIK, MEHMET; Hasanlı, Nızamı (2012-10-15)
Spectroscopic ellipsometry measurements were carried out on TlSe single crystals for orientations of electric field, parallel (E parallel to c), and perpendicular (E perpendicular to c) to optic axis c. The experiments were performed in the 1.2-6.2 eV spectral range at room temperature. The real and imaginary parts of the pseudodielectric function as well as pseudorefractive index and pseudoextinction coefficient were calculated from the analysis of ellipsometric data under the light of ambient-substrate op...
