The frequencies of lattice vibrations are calculated for compounds of the type T1BX2 on the basis of the linear-chain model. The calculated frequencies are compared with experimental values for TlGaS2 and TlGaSe2. The good agreement between the calculated and experimental frequencies serves as proof of the applicability of the linear-chain model to compounds of the T1BX2 type. The proposed method of calculation of frequencies makes it possible to predict the theoretical frequencies of lattice vibrations of ternary compounds that have a chain structure.

Spectroscopic study and numerical simulation of low-pressure radio-frequency capacitive discharge with argon downstream Tanisli, Murat; Rafatov, İsmail; Sahin, Neslihan; Mertadam, Sercan; Demir, Suleyman (Canadian Science Publishing, 2017-02-01) In this study, the characteristic properties and plasma parameters of capacitive radio frequency (RF) argon (Ar) discharge and supplementary discharge at low pressure are investigated with optical emission spectroscopy (OES). The wavelengths of spectral lines from OES are obtained between 650-900 nm. Using OES lines and related experimental data, the electron temperatures for different RF power, flow, and measurement periods are determined. Eventually, the properties of plasma including the electron tempera...
Nonlinear mode coupling and sheared flow in a rotating plasma Uzun Kaymak, İlker Ümit; Choi, S.; Clary, M. R.; Ellis, R. F.; Hassam, A. B.; Teodorescu, C. (IOP Publishing, 2009-01-01) Shear flow is expected to stabilize the broad spectrum of interchange modes in rotating plasmas. However, residual fluctuations may still persist. To investigate the presence of such fluctuations, sixteen magnetic pickup coils equally spaced on a crown have been mounted inside the vacuum vessel, at the edge of a rotating plasma in mirror configuration. A comprehensive analysis of the magnetic fluctuations shows that very low spatial mode numbers survive under the imposed shear flow. Nevertheless, temporal F...
Progressive structural and electronic properties of nano-structured carbon atomic chains Usanmaz, D.; Srivastava, G. P. (AIP Publishing, 2013-05-21) Ab initio calculations, based on the planewave pseudopotential method and the density functional theory, have been reported on the changes in the electronic and structural properties of short carbon atomic chains held rigidly between hydrogenated thin armchair graphene nanoribbons (N-a-AGNR) of dimer line numbers N-a = 4 and 5. We have considered chains of several lengths (n = 4-9 atoms) and with different forms of attachment with the AGNRs. It is found that odd-numbered chains are metallic in nature, with ...
Singular potentials and moving boundaries in 3D Yuce, C (Elsevier BV, 2004-02-16) In this Letter, the problem of a spinless particle under the time-dependent harmonic oscillator potential and a singular potential with a moving boundary is studied in the spherical coordinates. Some transformations are used to transform the moving boundary conditions to the fixed boundary conditions. An exact solution is constructed.
Energy distribution of the universe in the Bianchi type II cosmological models Aydogdu, O (Wiley, 2006-04-01) Using the energy-momentum complexes of Tolman, Papapetrou and Weinberg, the total energy of the universe in Locally Rotationally Symmetric (LRS) Bianchi type II models is calculated. The total energy is found to be zero due to the matter plus field. This result supports the viewpoint of Tryon, Rosen and Albrow. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
