Calculation of the raman frequency, damping constant (Linewidth) and the relaxation time near the tetragonal-cubic transition in PbTiO3

Kiracı, Ali; Yurtseven, H. (Elsevier GMBH, 2017)

Frequencies, damping constants and the relaxation times of some Raman modes including the two soft modes are calculated as a function of pressure near the tetragonal-cubic transition in PbTiO3. Calculation of the Raman ...

Kiracı, Ali; Yuetseven, Hamit (Elsevier GMBH, 2017)

Frequencies, damping constants and the relaxation times of some Raman modes including the two soft modes are calculated as a function of pressure near the tetragonal-cubic transition in PbTiO3. Calculation of the Raman ...
Determination of trapping parameters of Tl2In2S3Se layered single crystal by thermoluminescence

Güler, İpek; Gasanly, Nizami (Wiley, 2018-04)

Thermoluminescence (TL) measurements are performed to evaluate the trap states in Tl2In2S3Se layered single crystals. TL experiments are conducted with varying temperature from 10 to 300 K and warming rates from 0.2 to 1.0 ...
Optical and photoelectrical properties of TlInSSe layered single crystals

Güler, İpek; Gasanly, N. (Elsevier GMBH, 2018)

Optical and electrical properties of TlInSSe layered single crystals have been studied by means of transmission, reflection and photoconductivity measurements. Transmission and reflection experiments have been carried out ...
Pressure dependence of the Raman frequency calculated from the volume data close to the ferroelectric-paraelectric transition in PbTiO3

Yurtseven, Hamit; Kiracı, Ali (Taylor&Francis, 2017)

We calculate the pressure dependence of the Raman frequencies of some Raman modes by using the observed volume data through the mode Gruneisen parameters for the ferroelectri-paraelectric transition in PbTiO3. The mode ...
Pressure-dependent Raman modes near the cubic-tetragonal transition in strontium titanate

Kiracı, Ali; Yurtseven, Hamit (Wiley, 2018-03)

The pressure dependence of the Raman frequency shifts of various Raman modes is calculated at room temperature using the volume data from the literature for the cubic-tetragonal transition in SrTiO3. The isothermal mode ...
Temperature dependence of the damping constant and the relaxation time close to the tetragonal-cubic phase transition in SrZrO3

Yurtseven, H.; Kiracı, Ali (Elsevier Science BV, 2017-01-15)

The damping constant Gamma(sp) due to the pseudospin-phonon coupling is calculated as a function of temperature using the pseudospin-phonon coupled model and the energy fluctuation model close to the tetragonal-cubic ...
Temperature dependence of the polarization, dielectric constant, damping constant and the relaxation time close to the ferroelectric-paraelectric phase transition in LiNbO3

Kiracı, Ali; Yurtseven, H. (Elsevier GMBH, 2017)

We calculate the order parameter (spontaneous polarization) and the inverse dielectric susceptibility at various temperatures in the ferroelectric phase of LiNbO3 for its ferroelectric-paraelectric phase transition (T-C ...
