Both dc and ac transport characteristics of plasma enhanced chemical vapor deposited (PECVD) boron nitride (BN) thin film was investigated by dc current vs. dc voltage measurement at different temperatures and admittance vs. gate voltage at various frequencies/temperatures, respectively. MIM metal (Al)-insulator (BN)-metal (Al) or MIS metal (Al)-BN-semiconductor (p-Silicon) test devices were conventionally produced. Both conductivity anisotropy and dc/ac detailed transport mechanism were analyzed within the frame of a turbostratic structure (t-BN), interfacing the substrate by a thin amorphous layer (a-BN). This defective BN film has been justified by both infrared (IR) analysis and indirectly by the resulting electrical transport behavior. Transport and its Variations as a function of temperature/frequency are in agreement with a hopping mechanism across Gauss-like energy distributed localized deep traps.

Photoelectronic and electrical properties of InS crystals
Qasrawi, AF; Hasanlı, Nızamı (IOP Publishing, 2002-12-01)
To identify the localized levels in InS single crystals, the dark electrical conductivity, current-voltage characteristics and photoconductivity measurements were carried out in the temperature range of 10-350 K. Temperature dependence of dark electrical conductivity and the space-charge limited current studies indicate the presence of a single discrete trapping level located at (10 +/- 2) meV below the conduction band with a density of about 4.8 x 10(11) cm(-3). The conductivity data above 110 K reveal an ...
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...
Photoelectronic, optical and electrical properties of TlInS2 single crystals
Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2003-09-01)
To specify the donor energy levels in TlInS2 single crystals, the dark electrical resistivity, photoconductivity and Hall measurements were carried out in the temperature range of 100-400 K, 110-350 K and 170-400 K, respectively. The Hall measurements revealed that the crystals exhibit an anomalous behavior of Hall voltage by changing sign (from p-type to n-type conductivity) at 315 K. By means of the temperature dependence of dark electrical resistivity, Hall coefficient and photocurrent measurements the d...
Investigation of localized levels in GaS0.5Se0.5 layered crystals by means of electrical, space-charge limited current and photoconductivity measurements
Qasrawi, AF; Hasanlı, Nızamı (Wiley, 2002-11-16)
To identify the localized levels in GaS0.5Se0.5 single crystals, the dark electrical conductivity, current-voltage characteristics and photoconductivity measurements were carried out in the temperature range of 250-400 K. Temperature dependence of dark electrical conductivity and the space-charge limited current studies indicate the presence of a single discrete trapping level located at 0.31 eV below the conduction band with a density of about 1.3 x 10(15) cm(-3). The conductivity data above 320 K reveal a...
