Functionalization of graphdiyne, a two-dimensional atomic layer of sp-sp(2) hybrid carbon networks, was investigated through first-principles calculations. Hydrogen or halogen atoms preferentially adsorb on sp-bonded carbon atoms rather than on sp(2)-bonded carbon atoms, forming sp(2)- or sp(3)-hybridization. The energy band gap of graphdiyne is increased from ~0.5 eV to ~5.2 eV through the hyd...

Control over electron-spin states, such as coherent manipulation, filtering and measurement promises access to new technologies in conventional as well as in quantum computation and quantum communication. In this paper, we review recent theoretical proposal of using electron spins in quantum confined structures as qubits. We also present a theoretical proposal for testing Bell’s inequality in n...

We report and solidly interpret the infrared spectrum of both pristine and oxidized carbynes embedded in a pure-carbon matrix. The spectra probe separately the effects of oxidation on sp- and on sp(2)-hybridized carbon, and provide information on the stability of the different structures in an oxidizing atmosphere. The final products are mostly short end-oxidized carbynes anchored with a double...

Nanolithography is the key technology driving technological progress in electronics, photonics, information technology and biotechnology. The tools and techniques used in the semiconductor industry have become too expensive for applications other than high-volume manufacturing. Masks, which are required for each unique design, can cost tens of thousands of dollars per layer. This economic const...

Advances in nano-electronics VLSI manufacturing technology and the rapid downscaling of the size of logic circuits have made them more prone to errors. This has led to the need for fast circuit reliability evaluation of large logic circuits. In this paper a new method for reliability analysis of VLSI logic circuits based on a modified form of Mason’s rule is proposed. Utilizing matrix sparsity ...

Zinc Oxide (ZnO) nano-superstructures (NSSs) have attracted intense research interests due to their large surface areas and unique properties. In this work, we report an original approach to synthesize ZnO NSSs in a one-step manner with a hydrothermal method. The crystalline structures and growth mechanism can be understood by surface energy calculations. The reaction kinetics was investigated ...

Many problems in nano and molecular electronics require the solution of the Schrodinger equation for scattering states. R-matrix theory, a technique first introduced in nuclear physics and widely used in atomic and molecular physics, has recently been adapted to calculate the transport properties of solid-state devices. We have extended R-matrix theory to the general case of two-dimensional dev...
