The temperature dependence of the polarization P and the tilt angle theta is calculated here in the presence of a constant electric field near the smectic AC* phase transition of a ferroelectric liquid crystal using a mean field model. We demonstrate here the temperature dependence of P and theta under some fixed electric fields for the ferroelectric liquid crystal of 4-(3-methyl-2-chlorobutanoyloxy)-4'-heptyloxybiphenyl. Our predicted values of P and theta at various temperatures under fixed electric fields, follow similar critical behaviour as predicted for zero electric field from the mean field model near the smectic AC* phase transition in 4-(3-methyl-2-chlorobutanoyloxy)-4'-heptyloxybiphenyl.

Critical behaviour of the polarization, tilt angle, electric susceptibility and the specific heat close to the SmA-ferroelectric SmC (SmC*) phase transitions Yurtseven, Hasan Hamit; Kilit, E. (Informa UK Limited, 2006-01-01) This study gives the temperature dependence of the two order parameters, namely, polarization P and the tilt angle theta, when there is a biquadratic coupling P-2 theta(2) in the expansion of the Landau free energy. This applies to the electric-field-induced SmA-Ferro-Electric SmC (SmC*) phase transition. From this expansion of the Landau free energy in terms of the polarization and the tilt angle, we obtain the temperature dependence of the electric susceptibility chi and the electric field dependence of t...
Temperature effect on dark electrical conductivity, Hall coefficient, space charge limited current and photoconductivity of TlGaS2 single crystals Qasrawi, AF; Hasanlı, Nızamı (IOP Publishing, 2005-05-01) The dark electrical conductivity, Hall coefficient, space charge limited current, and illumination and temperature dependences of the photocurrent of TIGaS2 single crystals in the temperature regions of 100-350, 200-350, 200-290 and 100-350 K, respectively, have been measured and analysed. The Hall coefficient measurements revealed the extrinsic type of conduction with conductivity-type conversion from p- to n-type at a critical temperature of 315 K. The temperature dependence of the dark electrical conduct...
Optoelectronic and electrical properties of TlGaS2 single crystal Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2005-10-01) The optoelectronic and electrical properties of TIGaS2 single crystals have been investigated by means of room temperature transmittance and reflectance spectral analysis, Hall coefficient, dark electrical resistivity and photocurrent measurements in the temperature range of 200-350 K. The optical data have revealed an indirect and direct allowed transition band gaps of 2.45 and 2.51 eV, an oscillator and dispersion energy of 5.04 and 26.45 eV, respectively, a static dielectric constant of 6.25 and static r...
Nonlinear Seebeck and Peltier effects in quantum point contacts Çipiloğlu, Mustafa A; Turgut, Sadi; Tomak, Mehmet (Wiley, 2004-09-01) The charge and entropy currents across a quantum point contact are expanded as a series in powers of the applied bias voltage and the temperature difference. After that, the expansions of the Seebeck voltage in temperature difference and the Peltier heat in current are obtained. With a suitable choice of the average temperature and chemical potential, the lowest order nonlinear term in both cases appear to be of third order. The behavior of the third-order coefficients in both cases are then investigated fo...
Temperature-Dependent Electrical Characteristics of Au/Si3N4/4H n-SiC MIS Diode Yigiterol, F.; Güllü, Hasan Hüseyin; Bayraklı, Özge; YILDIZ, DİLBER ESRA (Springer Science and Business Media LLC, 2018-05-01) Electrical characteristics of the Au/Si3N4/4H n-SiC metal–insulator-semiconductor (MIS) diode were investigated under the temperature, T, interval of 160–400 K using current–voltage (I–V), capacitance–voltage (C−V) and conductance–voltage (G/ω−V) measurements. Firstly, the Schottky diode parameters as zero-bias barrier height (ΦB0) and ideality factor (n) were calculated according to the thermionic emission (TE) from forward bias I–V analysis in the whole working T. Experimental results showed that the valu...
