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.
ELECTRON POLARIZATION IN A QUANTUM-WELL WITH UNIFORM ELECTRIC-FIELD ILAIWI, KF; Tomak, Mehmet (1991-06-01) The polarization of a quantum electron confined in a one-dimensional potential well in the presence of a uniform electric field is calculated numerically. We find that the negative polarization of the first excited state in previous calculations is solely due to the neglect of the electric field outside the quantum well.
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...
Exciton related nonlinear optical properties of a spherical quantum dot Aksahin, E.; Unal, V. Ustoglu; Tomak, Mehmet (2015-11-01) The nonlinear optical properties of an exciton in a spherical quantum dot (QD) is studied analytically. The nonlinear optical coefficients are calculated within the density matrix formalism. The electronic problem is solved within the effective mass approximation. The contributions from the competing effects of the confinement, the Coulomb interaction, and the applied electric field are calculated and compared with each other. We have made no assumptions about the strength of the confinement. We concentrate...
Optical absorption of a quantum well with an adjustable asymmetry Yildirim, H.; Tomak, Mehmet (Springer Science and Business Media LLC, 2006-04-01) The effects of asymmetry and the electric field on the electronic subbands and the nonlinear intersubband optical absorption of GaAs quantum wells represented by a Poschl-Teller confining potential are studied. The potential itself can be made asymmetric through a correct choice of its parameter set and this adjustable asymmetry is important for optimizing the absorption. In that way optimal cases can be created. We calculate the modified wave functions and electronic subbands variationally. The linear and ...
