Nano Cd0.9Mg0.05S was synthesized applying the thermolysis technique in air and under flow of nitrogen. Samples obtained exhibited CdS structure with two phases. Rietveld refinement analysis used to determine different parameters. Analysis UV–Vis absorption spectra disclosed that optical band gap sample prepared N2 is less than corresponding air. The (air) decreased as it doped Mg while increas...

A single-walled carbon nanotube (SW-CNT) is a nano scale tube formed by a cylindrical shell of single atomic layer of carbon atoms. Nanotubes have diameter of a few nm and length up to 100μm so that they form extremely thin wires. The atomic structure of SWCNT can be formed by wrapping a stripe of single atomic layer of graphite sheet along a certain direction, and this direction determines the...

Nano-porous metallic matrixes (NMMs) offer superior surface to volume ratios as well as enhanced optical, photonic, and electronic properties to bulk metallic materials. Such behaviours are correlated to the nano-scale inter-grain metal domains that favour the presence of electronic vacancies. In this work, continuous 3D NMMs were synthesized for the first time through a simple diffusion-reduct...

The magnetic and electronic properties of hydrogenated and halogenated group-IV zigzag nanoribbons (ZNRs) are investigated by first-principles density functional calculations. Fascinatingly, we find that all the ZNRs have magnetic edges with a rich variety of electronic and magnetic properties tunable by selecting the parent and passivating elements as well as controlling the magnetization dire...

Copyright 2012 Novel SiGe Processes and Devices for Nano-Photonics Applications PI: Prabhakar Bandaru Experts in the photonics industry see potential in the integration of Germaniumbased optical components with conventional CMOS-based electronics, allowing for the development of opto-electronic integrated circuits with superior performance and functionality (compared to optical or electronic ci...

We demonstrate a semiconductor PCSEL array that uniquely combines an in-plane waveguide structure with nano-scale patterned PCSEL elements. This novel geometry allows two-dimensional electronically controllable coherent coupling of remote vertically emitting lasers. Mutual coherence of the PCSEL elements is verified through the demonstration of a two-dimensional Young's Slits experiment. In add...

A possibility of growing highly mismatched and yet two-dimensional heteroepitaxial deposits, is both fascinating in terms of basic science and technologically important. So far, stabilization of flat morphology by a reduction of the overall electron energy in a quantum well (hence termed ‘‘electronic growth’’), has been observed exclusively in heteroepitaxy of simple metals, lead, and silver. T...

Ever since the invention of the transistor and the possibility to integrate these on a large scale in integrated circuits, miniaturization of electronic devices has become pervasive throughout society. And not only electronic devices are subject to miniaturization, all kinds of man-made structures and products are being made smaller and smaller, in the process retaining their function, and ofte...
