For the first time theoretical (in terms of the classical theory of ordering) and experimental (with the adiabatic calorimeter method) investigations are made of the effect of a third component impurity C on the heat capacity of A3B‐type ordered alloys with FCC structure. The effect of the impurities Mn, Cr, Mo, or W on the heat capacity of Ni3Fe alloys is analysed as an example. The comparison of the theoretical results with the experimental data shows good qualitative agreement.

A NEW CLASS OF EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTIONS FOR BULK AND CLUSTER PROPERTIES Erkoç, Şakir (Wiley, 1992-06-01) A new empirical many-body potential energy function (PEF) is proposed, which comprices two- and three-body atomic interactions. The two-body potential is a kind of hybrid function and the three-body potential is formed by additive and nonadditive functions. The additive part is expressed in terms of two-body interactions, and the nonadditive part is expressed as triple-dipole function. The PEF satisfies bulk cohesive energy, bulk stability condition, and bulk modulus. The PEF is parameterized for gold, silv...
Analysis of the Spontaneous Polarization and the Dielectric Constant Near the Ferroelectric Phase Transition in TSCC Yurtseven, Hasan Hamit (Informa UK Limited, 2008-01-01) The temperature dependence of the spontaneous polarization and the dielectric constant has been analyzed for the fixed pressures of 0.001,1 and 2.2 kbar close to the phase transitions in TSCC. This analysis is performed using the experimental data for TSCC according to a power-law formula. From our analysis, using the experimental data for the spontaneous polarization, we deduce the values of the critical exponent = 0.32 (1 bar), 0.28 (1 kbar) and 0.26 (2.2 kbar) for the spontaneous polarization near the tr...
The exciton transition energies in symmetric double GaAs/AlxGa1-xAs quantum wells Okan, SE; Aktas, S; Akbas, H; Tomak, Mehmet (Wiley, 1999-04-01) The exciton transition energies between valence and conduction subbands of symmetric double quantum wells are studied. To study the effect of geometry coupled wells of rectangular, graded and parabolic shapes are considered. A special emphasis is given to the study of crossover between the symmetric light-hole (e1-11) and the antisymmetric heavy-hole (e2-h2) transitions.
The effect of Ga/In ratio and annealing temperature on the nonlinear absorption behaviors in amorphous TlGaxIn(1-x)S2 (0 ≤ x ≤ 1) chalcogenide thin films Ünlü, Bekir Asilcan; Karatay, Ahmet; Yüksek, Mustafa; Ünver, Hüseyin; Hasanlı, Nızamı; Elmali, Ayhan (Elsevier BV, 2020-08-01) The amorphous semiconductor TlGaxIn(1-x)S2 (0 <= x <= 1) chalcogenide thin films were prepared with 70 nm thicknesses by using vacuum evaporation technique. The nonlinear absorption properties of the films were studied by Z-scan technique. The energy band gap values were calculated by using linear absorption spectra. The effect of Ga/In ratio leads to increase 0.22 eV in band gap energy. To derive the transmission in open aperture Z-scan data, a theoretical model incorporating two photon and free carrier ab...
Correlations between Raman frequency shifts and the thermodynamic quantities close to the melting point in D2O ice Karacali, H; Yurtseven, Hasan Hamit (Wiley, 2005-11-01) The Raman frequency shifts (1/v) (partial derivative v/partial derivative T)(T) and (1/v) (partial derivative v/partial derivative P)(T) of the translational mode are correlated to the specific heat C-p and to the thermal expansivity alpha(p), respectively, in D2O ice. Close to the melting point, they correlate linearly, from which the values of the slope dP/dT have been deduced in D2O ice. Our calculated values of dP/dT are in very good agreement with the experimentally obtained value in this crystalline s...
