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 temperature are identified. In addition, the numerical modelling of the discharge parameters is carried out by using the "extended" fluid model for plasma, and consistency between numerical and experimental results is discussed.

Singularities of spectra of infrared reflection of tertiary compounds of the type T1BX2
Hasanlı, Nızamı; Khomutova, M.D.; Sardarly, R.M.; Tagorov, V.I. (Springer Science and Business Media LLC, 1977-07-01)
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 ...
Spatial variations of non-uniform argon glow discharge
Akbar, D.; Bilikmen, S.; Akbar, H. (Springer Science and Business Media LLC, 2006-01-01)
The spatial variation of a non-uniform glow discharge due to the different diameters of the same discharge tube on the plasma parameters is attracting a considerable attention. For this reason the fundamental spatial plasma parameters of an argon. glow discharge have been measured by using fast three couple of Langmuir double probe (TCDP) technique. The orbital motion limited (OML) theory has been used, since the probe radius is smaller than Debye length xi < 1. The axial and radial variation of the electro...
Optical absorption and reflection studies of Tl4InGa3S8 layered single crystals
Goksen, K.; Hasanlı, Nızamı; Ozkan, H. (Institute of Physics, Polish Academy of Sciences, 2007-07-01)
The optical properties of Tl4InGa3S8 layered single crystals have been studied by means of transmission and reflection measurements in the wavelength region between 400 and 1100 nm. The analysis of the room temperature absorption data revealed the presence of both optical indirect and direct transitions with band gap energies of 2.40 and 2.61 eV, respectively. Transmission measurements carried out in the temperature range of 10-300 K revealed the rate of change of the indirect band gap with temperature as g...
Non-uniform axial electric field in argon glow discharge plasma
Akbar, D.; Bilikmen, S. (IOP Publishing, 2006-05-01)
The non-uniform argon dc glow discharge plasma system has been constructed in a very special design to investigate the effects of variable tube radius on plasma parameters. By using isolated computer controlled three couples of a double probe (TCDP) system, the electron temperature, electron density, the reduced electric field, and electron drift velocity are measured at low and intermediate pressures. It is shown that the electron temperature and reduced electric field (density) decreases (increases) as th...
Photovoltaic Effect and Space Charge Limited Current Analysis in TlGaTe2 Crystals
QASRAWI, ATEF FAYEZ HASAN; Yaseen, T. R.; Eghbariy, B.; Hasanlı, Nızamı (Institute of Physics, Polish Academy of Sciences, 2012-07-01)
Anisotropic space charge limited current density analysis and photovoltaic effect in TlGaTe2 single crystals has been investigated. It is shown that, above 330 K, the crystal exhibits intrinsic and extrinsic type of conductivity along (c-axis) and perpendicular (a-axis) to the crystal's axis, respectively. The current density (J) is found to be space charge limited. It is proportional to the square and three halves power of voltage (V) along the a- and c-axis, respectively. Along the a-axis and at sufficien...
