Variation of the lattice parameters and thermal expansion coefficients of Bi-2223 superconductor have been measured from room temperature up to the melting point using X-ray diffraction. The lattice parameters (a and c) gradually increase up to about 250 degrees C. Between 250 degrees C to 450 degrees C the variation of the lattice parameters are quite anomalous, in that a remains almost constant while c decreases. From 450 degrees C to 600 degrees C both parameters gradually increase. Above 650 degrees C the structure of Bi-2223 becomes unstable. The initial thermal expansion coefficient along the c-axis is about four times that along the a-axis. Similar large anisotropy has also been observed in the measurements of the stress of Bi-2223.

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...
Temperature dependence of the Raman bandwidths and intensities of a lattice mode near the tricritical and second order phase transitions in NH4Cl
Karacali, H; Yurtseven, Hasan Hamit (2006-01-11)
We calculate here the temperature dependence of the damping constant using the expressions derived from the Matsushita's theory and the temperature dependence of the order parameter from the molecular field theory for the tricritical (1.5 kbar) and second order (2.8 kbar) phase transitions in NH4Cl. Our calculations are performed for the nu(5) (174 cm(-1)) Raman mode of NH4Cl for the pressures studied. Predictions for the damping constant are in good agreement with our observed Raman bandwidths of this latt...
Effect of isomorphic atom substitution on the lattice parameters and the optical absorption edge of TIGaSe2-TllnSe2 mixed crystals
Hasanlı, Nızamı (2006-05-01)
The variation of lattice parameters of TlGaSe2-TlInSe 2 mixed crystals with composition have been investigated by using of X-ray diffraction technique. For the mixed crystals studied, a structural phase transition (monoclinic to tetragonal) due to atom substitution is observed when the sum of the tetrahedral covalent radii of the Ga(In) and the Se atoms in Ga(In)Se4 tetrahedra reaches a critical value of about 0.254 nm. From transmission and reflection measurements, the compositional dependence of the indir...
Investigation of structural, electronic, magnetic and lattice dynamical properties for XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds
Surucu, Gokhan; IŞIK, MEHMET; CANDAN, ABDULLAH; Wang, Xiaotian; Güllü, Hasan Hüseyin (Elsevier BV, 2020-06-15)
Structural, electronic, magnetic, mechanical and lattice dynamical properties of XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds have been investigated according to density functional theory and generalized gradient approximation. Among alpha, beta and gamma structural phases, gamma-phase structure has been found as the most stability characteristics depending on the calculated formation enthalpies, energy-volume dependencies and Cauchy pressures. Energy-volume plots of possible magnetic orders of gamma-phase ...
Investigation of structural and optical parameters of Cu-Ag-In-Se thin films deposited by thermal evaporation method
Gullu, H. H.; CANDAN, İDRİS; COŞKUN, EMRE; Parlak, Mehmet (2015-01-01)
Annealing effect on the structural and optical properties of the quaternary Cu-Ag-In-Se thin film deposited by the thermal evaporation has been investigated. The evaporation source was prepared by using vertical Bridgman-Stockbarger crystal growth system. Structural analysis indicated that annealing the films following to the deposition resulted in the changes from amorphous to polycrystalline phase with the preferred orientation along (1 1 2) direction. In order to determine the optical properties of the t...
