Dielectric and piezoelectric properties of PZT ceramics doped with strontium and lanthanum
Kalem, Volkan; Çam, İbrahim; Timucin, Muharrem (Elsevier BV, 2011-05-01)
PZT based piezoelectric ceramics obtained by doping with various levels of Sr2+ and La3+, designated as PSLZT, were prepared by conventional processing techniques. The effects of Sr2+ and La3+ additions, and that of the Zr/Ti ratio on microstructure, on phase constitution, and on the dielectric and piezoelectric properties were investigated. XRD data revealed that all PSLZT compositions had perovskite structure in which increasing Sr and/or decreasing Zr/Ti ratio increased the tetragonality. In PSLZT cerami...

Qasrawi, A. F.; Abu-Zaid, Samah F.; Ghanameh, Salam A.; Hasanlı, Nızamı (2014-05-01)
The room temperature, dark and photo-dielectric properties of the novel crystals TlGaSeS are investigated in the frequency, intensity and biasing voltage having ranges of similar to 1-120 MHz, 14-40 klux and 0-1 V, respectively. The crystals are observed to exhibit a dark high frequency effective dielectric constant value of similar to 10.65 x 10(3) with a quality factor of similar to 8.84 x 10(4) at similar to 120 MHz. The dielectric spectra showed sharp resonance-antiresonance peaks in the frequency range...
Dielectric functions and interband critical points of anisotropic chain structured TlSe single crystals
IŞIK, MEHMET; Hasanlı, Nızamı (2012-10-15)
Spectroscopic ellipsometry measurements were carried out on TlSe single crystals for orientations of electric field, parallel (E parallel to c), and perpendicular (E perpendicular to c) to optic axis c. The experiments were performed in the 1.2-6.2 eV spectral range at room temperature. The real and imaginary parts of the pseudodielectric function as well as pseudorefractive index and pseudoextinction coefficient were calculated from the analysis of ellipsometric data under the light of ambient-substrate op...

Yildiz, Dilber Esra; APAYDIN, Dogukan Hazar; Toppare, Levent Kamil; Çırpan, Ali (2013-05-05)
Dielectric and electrical properties of a benzotriazole and fluorene copolymer were investigated using current-voltage (IV), capacitance-voltage (CV), and conductancevoltage (G/wV) measurements at room temperature. The electrical parameters, barrier height (phi Bo), and ideality factor (n) obtained from the forward bias LnI-V plot were found as 0.453 eV and 2.08, respectively. The Rsvalues were found as 2.20, 2.12, 1.90 using dV/dLnIversus I, H(I)versus I and F(V)-V plots,respectively. The dielectric consta...
Dielectric Analysis of Changes in Electric Properties of Doxorubicin Resistant K562 Leukemic Cells Through Electrorotation with 3 D Electrodes
Garsha, Bahrieh; Erdem, Murat; Özgür, Ebru; Gündüz, Ufuk; Külah, Haluk (2013-10-31)
In this study, dielectric characterization of multidrug resistant (MDR) K562 human leukemia cells was carried out using a MEMS-based electrorotation (ER) device with 3D electrodes. Different cell populations were utilized, which were resistant to 0.1, 0.3, and 0.5 μM doxorubicin. The ER devices with 3D quadruple electrodes (30 urn in height) were used, in order to eliminate the fringing field effect on the rotation of cells. Signals in phase quadrature were applied to the polynomial electrodes, to induce th...
