Öğe Binding energy of the donor impurities in GaAs-Ga1-xAlxAs quantum well wires with Morse potential in the presence of electric and magnetic fields(IOP PUBLISHING LTD, 2016) Aciksoz, Esra; Bayrak, Orhan; Soylu, AsimThe behavior of a donor in the GaAs-Ga1-xAlxAs quantum well wire represented by the Morse potential is examined within the framework of the effective-mass approximation. The donor binding energies are numerically calculated for with and without the electric and magnetic fields in order to show their influence on the binding energies. Moreover, how the donor binding energies change for the constant potential parameters (D-e, r(e), and a) as well as with the different values of the electric and magnetic field strengths is determined. It is found that the donor binding energy is highly dependent on the external electric and magnetic fields as well as parameters of the Morse potential.Öğe Effect of the velocity-dependent potentials on the energy eigenvalues of the Morse potential(VERSITA, 2012) Soylu, Asim; Bayrak, Orhan; Boztosun, IsmailWe investigate the effect of the isotropic velocity-dependent potentials on the bound state energy eigenvalues of the Morse potential for any quantum states. When the velocity-dependent term is used as a constant parameter, rho(r) = rho (0), the energy eigenvalues can be obtained analytically by using the Pekeris approximation. When the velocity-dependent term is considered as an harmonic oscillator type, rho(r) = rho (0) r (2), we show how to obtain the energy eigenvalues of the Morse potential without any approximation for any n and a"" quantum states by using numerical calculations. The calculations have been performed for different energy eigenvalues and different numerical values of rho (0), in order to show the contribution of the velocity-dependent potential on the energy eigenvalues of the Morse potential.Öğe Hafif, orta ve ağır çekirdeklerin nükleer yapı ve reaksiyon gözlenirlerinin kümelenme modeli kullanarak teorik olarak incelenmesi(2016) Soylu, Asım; Dağtaş, Ramazan; Bayrak, Orhan; Koyuncu, Fahrettin; Yavuz, Fatma[Abstract Not Available]
