Electronic properties of a large quantum dot at a finite temperature Gulveren, B; Atav, U; Tomak, Mehmet (Elsevier BV, 2005-09-01) 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-interactin...
Electronic structure of a many-electron spherical quantum dot with an impurity Sahin, M; Tomak, Mehmet (American Physical Society (APS), 2005-09-01) We investigate the electronic structure of a many-electron spherical quantum dot with and without hydrogenic impurity. The number of electrons is taken as N=18. The density functional theory is used within local density approximation. Total energy, chemical potential, addition energy spectra, and the shell structure are determined and the results obtained are compared for cases with and without impurity. It is observed that the capacitive energy with the impurity increases in the 1s shell with respect to th...
Electronic structure of the chainlike compound TlSe Ellialtıoğlu, Süleyman Şinasi; Mete, E; Shaltaf, R; Allakhverdiev, K; Gashimzade, F; Nizametdinova, M; Orudzhev, G (American Physical Society (APS), 2004-11-01) An ab initio pseudopotential calculation using density functional theory within the local density approximation has been performed to investigate the electronic properties of TlSe, which is of chainlike crystal geometry. The energy bands and effective masses along high symmetry directions, the density of states, and valence charge density distributions cut through various planes are presented. The results have been discussed in terms of previously existing experimental and theoretical data, and comparisons ...
Nonlinear intersubband optical absorption of Si delta-doped GaAs under an electric field Yildirim, Hasan; Tomak, Mehmet (Wiley, 2006-10-01) We study the nonlinear intersubband optical absorption of a single Si delta-doped GaAs sheet placed in the middle of a GaAs quantum well and subjected to an electric field. The Schrodinger and Poisson equations are solved self-consistently for various electric field strengths. The self-consistent solutions provide us with the correct confining potential, the wave functions, the corresponding subband energies and the subband occupations. The nonlinear optical intersubband absorption spectra are discussed wit...
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...
