Sub-bandgap optical absorption spectroscopy of hydrogenated microcrystalline silicon thin films prepared using hot-wire CVD (Cat-CVD) process
Hydrogenated microcrystalline silicon (μc-Si:H) thin films with different silane concentration (SC) have been prepared using the HW-CVD technique. Dual beam photoconductivity (DBP), photothermal deflection spectroscopy ...
Diffusion length measurements of microcrystalline silicon thin films prepared by hot-wire/catalytic chemical vapor deposition (HWCVD)
Hydrogenated microcrystalline silicon (μc-Si:H) films prepared by using the hot-wire/catalytic chemical vapor deposition (HWCVD) technique at low substrate temperatures between 185 °C and 220 °C with different silane ...
Fabrication of superconducting MgB2 from boron oxide (B 2O3), and its microstructural and electrical characterization
(National Institute of Optoelectronics, 2005-02)
The discovery of superconducting MgB2 (39 K) draws attention to it as a new material for applications based on superconductivity. Many researchers successfully synthesized MgB2 using commercial boron and magnesium. In this ...
Probing the phase diagram of Bi2Sr2CaCu 2O8+δ with tunneling spectroscopy
Tunneling measurements are performed on Ca-rich single crystals of Bi 2Sr2CaCu2O8+δ (Bi2212), with various oxygen doping levels, using a novel point contact method. At 4.2 K, SIN and SIS tunnel junctions are obtained with ...
Evolution of binaries towards HMXBs and LMXBs
(American Institute of Physics Publising, 2011)
In this study we investigate the evolution of binary systems towards low mass x-ray binaries and high mass x-ray binaries using Eggleton's binary star evolution code. © 2011 American Institute of Physics.
1/f noise in amorphous silicon and silicon-germanium alloys
We report measurements of conductance noise of a-Si1-XGeX:H in two different geometries; one where the current flow is transverse to the surface and the other longitudinal to it. Because of the large increase in sample ...
On the sources of CP-violation contributing to the electric dipole moments
In the framework of seesaw mechanism embedded in the constrained Minimal Supersymmetric Standard Model (cMSSM), phases of neutrino Yukawa coupling, μ-term and A-terms can all contribute to the Electric Dipole Moment (EDM) ...
Terahertz wave emission from layered superconductors: Interferometer measurements
Rectangular Bi2Sr2CaCu2O 8+δ (Bi2212) mesa structures were fabricated on as-grown Bi2212 single crystal superconductors using standard photolithography and Ar ion beam etching techniques. We have performed c-axis resistance ...
Magnetic cataclysmic variables
(American Institute of Physics Publising, 2010)
We present a study on magnetic cataclysmic variables (polars) using the collected data from the literature. These parameters (mass, radius, magnetic field intensity, mass transfer rate, etc.) and the relations between them ...
Extra dimensional metric reversal symmetry and its prospect for cosmological constant and zero-point energy problems, automatic pauli-villars-like regularization, and an interesting kaluza-klein spectrum
The metric reversal symmetry was introduced in the context of cosmological constant problem. Besides proposing a solution to the cosmological constant problem the metric reversal symmetry has also provided a framework for ...
