Magnetic properties of Co-doped SnO: first-principles calculations
Based on density functional theory calculations, the electronic and magnetic properties of Co-doped SnO are investigated. It is found that the spin-polarized state, with a magnetic moment of about 1.0 μ B per Co-dopant, is more favorable in energy than the non-spin-polarized state. Moreover, the origin of the ferromag…

Microstructure and field electron emission properties of boron doped diamond films
Boron doping into diamond film can improve its conductivity and enhance its applications in electronic device, electrochemical and biomedical sensing devices. In the present study, boron doped diamond films were deposited on Si(100) using trimethylboron as a boron source by microwave plasma chemical vapour deposition…
Anharmonic Optical Phonon Effects in ZnO Nanocrystals
Zinc oxide (ZnO) is a very promising material for optoelectrical devices operating at the short-wavelength end of the visible spectral range and at the near UV. The Raman scattering studies of ZnO heterolayers formed by isothermal annealing show sharp phonon lines. In addition to the A1(TO), E1(TO), E H 2 , and E1(LO)…
Pressure Dependence of Exciton Binding Energy in GaN/AlxGa1 - xN Quantum Wells
We present a theoretical study of excitons in GaN/Al x Ga 1-x N wurtzite (0001) quantum wells subjected to hydrostatic pressure. Our results show that the combined effect of pressure induced changes in band structure and piezoelectric field leads to reduction of the exciton binding energy. This subtle effect is descri…
Isobutyl Silane Precursors for SiCH Low-kCap Layer beyond the 22 nm Node: Analysis of Film Structure for Compatibility of Lowerk-value and High Barrier Properties
To form SiCH films with a high carbon content using plasma-enhanced chemical vapor deposition (CVD), isobutyl trimethylsilane (iBTMS) and diisobutyl dimethylsilane (DiBDMS) were examined as precursors for a low- k cap layer and Cu diffusion barrier at the top of Cu lines. We elucidated the relationship between the str…
Characteristic of Low Resistivity Fluorine-Doped SnO2Thin Films Grown by Spray Pyrolysis
Transparent conducting oxide films of fluorine-doped SnO 2 (FTO) were deposited on glass substrates by spray pyrolysis in order to determine the effect of spray solution concentration. These films were prepared with different F-doping concentrations from 0 to 33 mol %. The films were all polycrystalline with tetragona…
Density Functional Theory Study on the Interaction of O2Molecule with Cobalt–(6)Pyrrole Clusters
We have investigated the interaction between cobalt–(6)pyrrole [Co–(6)Ppy] clusters and O 2 molecule, including the adsorption and dissociation of O 2 molecule using the density functional theory (DFT) calculations. We found that O 2 molecule is adsorbed on Co–(6)Ppy clusters with side-on configuration and the O–O bon…
Morphological and Structural Changes in Cu(In,Ga)Se2Thin Films by Selenization Using Diethylselenide
The morphological and structural changes in Cu(In,Ga)Se 2 (CIGS) thin films during selenization using diethylselenide (DESe) are investigated. The surface morphology and extra phase existence of CIGS thin films strongly depend on the heating profile temperature and time of each step during selenization. Conventional h…
Role of Impurity Segregation into Cu/Cap Interface and Grain Boundary in Resistivity and Electromigration of Cu/Low-kInterconnects
The role of impurity segregation into the Cu/cap interface and grain boundary is discussed in terms of resistivity and electromigration (EM) lifetime. A Co-based metal capping, a CuAl seed, and new liners (Ti, Zr, and Hf) are compared as technologies for EM lifetime improvement. The roles of impurity in grain growth a…
High-Throughput Characterization Method for Crystallization Temperature of Integrated Thin Film Amorphous Alloys Using Thermography
We introduce the high-throughput characterization of the crystallization temperature T x of thin film amorphous alloys integrated into a thin film library. This characterization is achieved using thermography. A new thin film library is designed and fabricated using photolithography and a lift-off process. Using a hom…

Illumination of the growing layers has increased their thickness and improved film crystallini…
Growth of γ-In2Se3Thin Films by Electrostatic Spray Pyrolysis Deposition
γ-In 2 Se 3 thin films were grown by the electrostatic spray pyrolysis deposition growth technique. We investigated the dependence of the crystalline quality and optical properties of the grown films on the growth conditions, such as growth temperatures and the molar ratios of source material Se/In in the precursor so…
A novel sensing device for power system equipment condition monitoring
About 30 percent of all overhead power distribution outages are caused by failing electrical equipment, e.g., surge arresters, cutouts, insulators, wires, grounding, etc. Failing equipment can be located and scheduled for removal prior to an outage. Replacing failing equipment reduces all reliability index figures.
Box–Behnken optimization design and enhanced oral bioavailability of thymopentin-loaded poly (butyl cyanoacrylate) nanoparticles
This study was done to prepare thymopentin (TP5)-loaded poly (butyl cyanoacrylate) nanoparticles (TP5-PBCA-NPs) and evaluate thier efficacy for oral delivery. TP5-PBCA-NPs were prepared by emulsion polymerization, and the formulation was optimized based on Box-Behnken experimental design. The physico-chemical characte…
