Spin-orbit Interaction and Energy States in Nanoscale Semiconductor Quantum Rings

Li Y., Natl Nano Device Labs & Natl Chiao Tung Univ, TW

We investigate the effect of spin-orbit interaction on the electron energy states in nanoscale semiconductor quantum rings. The effective one-band Hamiltonian approximation with the spin-dependent Ben Daniel-Duke boundary conditions is formulated and solved numerically. Due [...]

Valence-band Energies of GaAs/AlGaAs and InGaAs/InP V-groove [1-10] Quantum Wires

Lassen B., Lew Yan Voon L.C., Melnik R., Willatzen M., Worcester Polytechnic Institute, US

Comparison between the Burt-Foreman and Luttinger-Kohn valence-band Hamiltonians have been performed for realistic V-groove GaAs/AlGaAs and InGaAs/InP quantum wires. Significant differences in band structure is only found for InGaAs/InP quantum wires.

Discontinuous Gold Films for Nanocell Memories

Nackashi D.P., Di Spigna N.H., Winick D.A., Amsinck C.J., Cheng L., Tour J.M., Franzon P.D., North Carolina State University, US

An important component to the nanocell, among other self-assembled networks, is the fabrication of a framework by which molecular elements can be interconnected. This framework must be nanometric in scale, created in a material suitable [...]

A Sub-40nm Nanostructured La0.7Sr0.3MnO3 Planar Magnetic Memory

Arnal T., Bibes M., Lecoeur Ph., Mercey B., Prellier W., Haghiri-Gosnet A.M., Institut d'Electronique Fondamentale IEF/UMR8622, FR

A single-step nanolithography planar process, which allows generating the core-element of a spin-polarized magnetic memory in the fully spin-polarized La0.7Sr0.3MnO3 (LSMO) manganite, is reported. Taking benefit of the proximity effects due to backscattered electrons, a [...]

Modeling of Nanoelectronic and Quantum Devices

Ferry D.K., Akis R., Gilbert M.J., Speyer G., Arizona State University, US

The semiconductor industry is constantly pushing towards ever smaller devices and it is expected that we will see commercial devices with gate lengths less than 10 nm within the next decade. Such small devices have [...]

Quantum Dots/Conductive Polymer Nanocomposite

Chen C-M, Chen H-S, Huang H-C, Chen C-M, Chen H-S, ITRI, TW

The nanocomposite composed of CdSe quantum dots and conductive polymer (MDMO-PPV) was investigated. The spherical 3.8-nm functionalized CdSe quantum dots were synthesized by colloidal chemical method. The conductive polymer MDMO-PPV was synthesized from 1-methoxyl-4-(3,7dimethyl-octanoxyl)benzene and [...]

Superposition Behavior in Babinet’s Effect on the Nano Au Particles Patterns

Wu S-C, Chen C-F, Chen H-L, Chao W-C, Chen C-F, Chen H-L, National Nano Device Laboratories, TW

The individual Babinet effect [1] in two types of complementary patterns can be added on a composed pattern mixed both patterns under the FTIR (Fourier Transform Infer-Red) spectroscopy measuring. That is the Babinet spectrum on [...]

Stochastic Analysis of Particle-Pair Transport in Brownian Ratchet Device

Retkute R., Gleeson J.P., University College Cork, IE

The motion of particle pairs in a Brownian ratchet device is studied using Langevin simulations. A Lennard-Jones interaction between the particles is added to a standard spring-bead model. The effects of such interaction upon a [...]

Multiscale (Nano-to-Micro) Design of Integrated Nanobio Systems

Jenkins J., Hagan M., Chakraborty A., Sundaram S., CFD Research Corporation, US

Biological systems have the first level of organization at the nanoscale. Proteins, DNA, RNA, ion channels are nanoscale systems that leverage molecular interactions to perform specific tasks. Integrated nano-bio systems have emerged as strong candidates [...]
