Recent developments in host-guest inclusion chemistry have paved the way to the controlled and reproducible assembly of sodalite and faujasite quantum dots and supralattices, the latter being comprised of regular arrays of monodispersed semiconductor (eg. AgX, WO3) quantum dots confined in a dielectric material. This work has led to the synthesis of the first examples of mixed component semiconductor quantum supralattices represented by the new sodalite family of materials (8-2n)Na,2nAg,(2-p)X,pY-SOD. Collective electronic coupling between these encapsulated and stabilized nanostructures can be altered through judicious variations in the host structure and guest loading. When the carrier wave function is restricted to the region of the imbibed nanostructures, quantum size effects (QSE's) are observed which give rise to differences in the optical, vibrational and magnetic resonance properties of these materials with respect to those of the bulk semiconductor parent. In this regime of strong quantum confinement, one anticipates resonant and non-resonant excitonic optical nonlinearities associated with χ(3) to be enhanced with respect to those of the respective quantum wire, quantum well, and bulk semiconductor materials.

Surface energy and excess charge in (1x2)-reconstructed rutile TiO2(110) from DFT plus U calculations Unal, Hatice; METE, ERSEN; Ellialtıoğlu, Süleyman Şinasi (2011-09-09) Physically reasonable electronic structures of reconstructed rutile TiO2(110)-(1x2) surfaces were studied using density functional theory (DFT) supplemented with Hubbard U on-site Coulomb repulsion acting on the d electrons, the so called DFT + U approach. Two leading reconstruction models proposed by Onishi and Iwasawa [Surf. Sci. Lett. 313, 783 (1994)] and Park and coworkers [Phys. Rev. B 75, 245415 (2007)] were compared in terms of their thermodynamic stabilities.
Nonlinear optical properties of semiconductor heterostructures Yıldırım, Hasan; Tomak, Mehmet; Department of Physics (2006) The nonlinear optical properties of semiconductor heterostructures, such as GaAsAl/GaAs alloys, are studied with analytic and numerical methods on the basis of quantum mechanics. Particularly, second and third-order nonlinear optical properties of quantum wells described by the various types of confining potentials are considered within the density matrix formalism. We consider a Pöschl-Teller type potential which has been rarely considered in this area. It has a tunable asymmetry parameter, making it a goo...
Physical properties of Pd, Ni metals and their binary alloys Özdemir Kart, Sevgi; Tomak, Mehmet; Department of Physics (2004) The Sutton Chen and quantum Sutton Chen potentials are used in molecular dynamics simulations to describe the structural, thermodynamical, and transport properties of Pd, Ni and their binary alloys in solid, liquid, and glass phases. Static properties including elastic constants, pair distribution function, static structure factor, and dynamical properties consisting of phonon dispersion relation, diffusion coefficient, and viscosity are computed at various temperatures. The melting temperatures for Pd-Ni s...
LATTICE POLYMERS - BEHAVIOR FAR FROM THETA-CONDITIONS YURTSEVER, E; ISSEVER, S (Elsevier BV, 1992-01-01) Two-dimensional Monte-Carlo simulations of lattice polymers were carried out employing Lennard-Jones (LJ) type intramolecular interactions. The shape-dependent properties of these polymers were studied over a large range of interaction parameters and temperatures. The variation of the critical constant was also analysed. Two-dimensional surfaces of sections were used to determine the portions of the parameter space which corresponded to theta-conditions. The behaviour of LJ polymers far from theta-condition...
Dielectric matrix influence on the photoluminescence properties of silicon nanocrystals Ferraioli, L.; Cazzanelli, M.; Daldosso, N.; Mulloni, V.; Bellutti, P.; Yerci, Selçuk; Turan, Raşit; Mikhaylov, A.n.; Tetelbaum, D.ı.; Pavesi, L. (null; 2006-12-01) Photoluminescence properties of silicon nanocrystals embedded in five different oxide matrices are analyzed. Samples are silicon rich oxide and oxynitride produced by PECVD and ion implantation and crystalline and amorphous aluminum oxide implanted with silicon.
