The physical properties of a two-dimensional parabolic quantum dot composed of large number of interacting electrons are numerically determined by the Thomas Fermi (TF) method at a finite temperature. Analytical solutions are given for zero temperature for comparative purposes. The exact solution of the TF equation is obtained for the non-interacting system at finite temperatures. The effect of the number of particles and temperature on the properties are investigated both for interacting and non-interacting cases. The results indicate that the effect of e e interaction on the density profile shows different temperature dependencies above and below a certain temperature T-c.

Nonlinear optical properties of a Woods-Saxon quantum dot under an electric field AYTEKİN, ÖZLEM; Turgut, Sadi; Unal, V. Ustoglu; Aksahin, E.; Tomak, Mehmet (Elsevier BV, 2013-12-01) A theoretical study of the effect of the confining potential on the nonlinear optical properties of two dimensional quantum dots is performed. A three-parameter Woods-Saxon potential is used within the density matrix formalism. The control of confinement by three parameters and an applied electric field gives one quite an advantage in studying their effects on the nonlinear properties. The coefficients investigated include the optical rectification, second and third-harmonic generation and the change in the...
ELECTRON POLARIZATION IN QUANTUM-WELLS WITH UNIFORM ELECTRIC-FIELD ILAIWI, KF; Tomak, Mehmet (Wiley, 1991-08-01) The polarization of a quantum electron confined in square, parabolic, and triangular quantum wells is calculated numerically. The aim of the present calculations is to compare the results for various geometries.
A parabolic quantum dot with N electrons and an impurity Gulveren, B; Atav, U; Sahin, M; Tomak, Mehmet (Elsevier BV, 2005-12-01) Ground-state properties of a two-dimensional quantum dot composed of N electrons and an impurity are investigated by the Thomas-Fermi (TF) method at T = 0. The changes induced by the impurity in electron density, chemical potential and total energy are calculated. Calculations are also performed for different number of particles and strength of confinement. The results indicate that Thomas-Fermi approximation is applicable even when the system contains only a few particles.
Segregation formation, thermal and electronic properties of ternary cubic CdZnTe clusters: MD simulations and DFT calculations KURBAN, MUSTAFA; Erkoç, Şakir (Elsevier BV, 2017-04-01) Surface and core formation, thermal and electronic properties of ternary cubic CdZnTe clusters are investigated by using classical molecular dynamics (MD) simulations and density functional theory (DFT.) calculations. In this work, MD simulations of the CdZnTe clusters are performed by means of LAMMPS by using bond order potential (BOP). MD simulations are carried out at different temperatures to study the segregation phenomena of Cd, Zn and Te atoms, and deviation of clusters and heat capacity. After that,...
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...
