Temperature dependences of the Raman frequency shifts and linewidths of vibrons ν1, ν2 and ν22 are calculated from the anharmonic self energy in the ε, δloc (localized δ) and δ phases of solid nitrogen (P = 18.5 GPa). This is performed by fitting the expressions from the the anharmonic self energy to the experimental frequency and FWHM data for those vibrons from the literature. Our results show that the anharmonic self energy model can explain adequately the observed behavior of the Raman frequency and linewidth of the vibrons for the transitions of the ε-δloc – δ in solid nitrogen. This method of analysis can also be applied to other some molecular solids close to the phase transitions.

Calculation of the Raman frequency shifts for the alpha phase of solid oxygen
Yurtseven, Hasan Hamit (Elsevier BV, 2017-01-01)
We calculate in this study the Raman frequencies of the two librons and one vibron at various pressures at constant temperatures of 10 K and also at the temperatures of 6 and 18 K by using the volume data from the literature through the mode Gruneisen parameter for the a phase of oxygen.
Calculation of the heat capacity Cp from the temperature-induced and pressure-induced Raman frequency shifts for solid benzene, naphthalene and anthracene
Ozdemir, Hilal; Yurtseven, Hasan Hamit (Elsevier BV, 2019-02-01)
The heat capacity Cp is calculated from the temperature-induced and pressure-induced Raman frequency shifts by means of the mode Griineisen parameter for the I-II transition of solid benzene, naphthalene and anthracene. For this calculation, contributions to Cp are considered due to the six lattice modes of solid benzene, six librational modes of naphthalene and, six phonons and nine vibrons of anthracene with their mode Griineisen parameters at various temperature (P = 0) and pressures (T=300 K). Our calcu...
Calculation of the soft-mode frequency for the alpha - beta transition in quartz
Yurtseven, Hasan Hamit (Elsevier BV, 2016-01-01)
The alpha - beta structural transition occurs in quartz at T-c = 846 K. The frequency of the soft mode associated with the volume increase, decreases with increasing temperature as the transition temperature is approached.
Calculation of the Infrared Frequencies as a Function of Temperature Using the Volume Data in the Ferroelectric Phase of NaNO2
Yurtseven, Hasan Hamit (Informa UK Limited, 2014-02-17)
We calculate the temperature dependence of the infrared frequencies of the TO and LO modes with the symmetries of A(1), B-1 and B-2 mainly in the ferroelectric phase of NaNO2. This calculation is carried out using the volume dependence of the infrared frequencies through the mode Gruneisen parameter in this crystal. The volume dependences of the infrared frequencies are fitted to the observed frequencies by using constant mode Gruneisen parameter in the ferroelectric phase of NaNO2. Our results show that th...
Investigation of electrical characteristics of Ag/ZnO/Si sandwich structure
Gullu, H. H.; Surucu, O. Bayrakli; Terlemezoğlu, Makbule; Yildiz, D. E.; Parlak, Mehmet (Springer Science and Business Media LLC, 2019-08-01)
In this study, temperature-dependent current-voltage (I-V), frequency-dependent capacitance-voltage (C-V) and conductance-voltage (G/omega-V) measurements are carried out for the electrical characterization of a zinc oxide (ZnO) thin film-based diode. The sandwich structure in the form of Ag/ZnO/Si/Al is investigated at temperatures between 220 and 360 K and in the frequency region of 1 kHz-1 MHz. ZnO thin film layer is deposited on a p-Si wafer substrate as a transparent conductive oxide layer by taking in...
