Confined states in multiple quantum well structures of SiGe nanowire superlattices
Nurten Akman, Engin Durgun, Seymur Cahangirov +1
Mechanical properties, atomic and energy band structures of bare and hydrogen passivated SiGe nanowire superlattices have been investigated by using first-principles ps…
Half-metallic silicon nanowires
Engin Durgun, Deniz Cakir, Nurten Akman +1
From first-principles calculations, we predict that transition metal (TM) atom doped silicon nanowires have a half-metallic ground state. They are insulators for one spin-direction…
The Wigner molecule in a 2D quantum dot
N. Akman, M. Tomak
The charge density and pair correlation function of three interacting electrons confined within a two-dimensional disc-like hard wall quantum dot are calculated by full numerical d…
Interacting electrons in a 2D quantum dot
N. Akman, M. Tomak
The exact numerical diagonalization of the Hamiltonian of a 2D circular quantum dot is performed for 2, 3, and 4 electrons.The results are compared with those of the perturbation t…
