An efficient method for the low-dimensional semiconductor structure is investigated. The method is applied to symmetric double rectangular quantum well as an example. A basis set of Cubic B-Splines is used as localized basis functions. The method compares well with analytical solutions and the finite difference method.

Thermal stability of Benzorod arrays: Molecular-dynamics simulations Malcıoğlu, Osman Barış (World Scientific Pub Co Pte Lt, 2005-05-01) A set of Benzorod arrays on a graphene substrate has been investigated by performing classical molecular-dynamics simulations. Benzorod is composed of aligned and dehydrogenated benzene rings that are stacked to form a rod-like structure. It has been found that the arrays considered axe thermally stable up to elevated temperatures, with a dependence on length.
Junction formation in crossed nanotubes under pressure: Molecular-dynamics simulations Tasci, E; Malcıoğlu, Osman Barış; Erkoc, A (World Scientific Pub Co Pte Lt, 2005-09-01) Junction formation in crossed C(10,0) single wall carbon nanotubes under pressure has been investigated, using classical molecular-dynamics simulations at 1 K. It has been found that a stable mechanical junction was formed by means of placing two crossed single wall carbon nanotubes between two rigid graphene layers which move toward each other.
Molecular-dynamics simulations of carbon nanocage structures: Nanoballs and nanotoroids Erkoç, Şakir; Vural, DC (World Scientific Pub Co Pte Lt, 2001-06-01) The structural stability of carbon nanocages, fullerens and toroids, have been investigated by performing molecular-dynamics computer simulations. The systems considered are C-120 and C-240 in ball and toroidal structures. Calculations have been realized by using an empirical many-body potential energy function for carbon. It has been found that C-120 ball is very unstable, and the other structures are relatively more strong against heat treatment.
EXACTLY SOLVABLE EFFECTIVE MASS D-DIMENSIONAL SCHRODINGER EQUATION FOR PSEUDOHARMONIC AND MODIFIED KRATZER PROBLEMS IKHDAİR, SAMEER; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2009-03-01) The point canonical transformation (PCT) approach is used to solve the Schrodinger equation for an arbitrary dimension D with a power-law position-dependent effective mass (PDEM) distribution function for the pseudoharmonic and modified Kratzer (Mie-type) diatomic molecular potentials. In mapping the transformed exactly solvable D-dimensional (D >= 2) Schrodinger equation with constant mass into the effective mass equation by using a proper transformation, the exact bound state solutions including the energ...
First-principles calculations for mechanical and electronic features of strained GaP nanowires Mohammad, Rezek; Katırcıoğlu, Şenay (World Scientific Pub Co Pte Lt, 2017-03-01) The mechanical and electronic properties of GaP nanowires are investigated by computing the Young's modulus, Poisson's ratio, energy band gap and effective carrier masses using first-principles calculations based on density functional theory. The wurtzite structural nanowires with diameters upper limited to similar to 27 angstrom are strained by uniaxial strains in the range of -7.5-7.5%. The Young's moduli of nanowires are found to be decreased with increase of the size in the direction of the Young's modu...
