Analysis of interface states of the pentacene organic thin-film phototransistor by conductance technique
A pentacene thin-film transistor with a channel width of 300 μm and a channel length of 30 μm has been successfully fabricated on n-Si substrate with thermally oxidized SiO2 as a gate insulator. The photovoltaic and interface ...
Structural and magnetic characterization of plasma ion nitrided layer on 316L stainless steel alloy
In this study, an FeCrNi alloy (316L stainless steel disc) was nitrided in a low-pressure R.F. plasma at 430 °C for 72 min under a gas mixture of 60% N2-40% H2. Structural, compositional and magnetic properties of the ...
Electrical and mechanical properties of superconducting MgB2/Mg metal matrix composites
(IOP Publishing, 2006)
MgB2/Mg composites were prepared using a metal matrix composite fabrication method that offers the potential to produce superconducting wires as an alternative approach to the powder in tube process. To obtain composites, ...
MgB2 superconducting thin films sequentially fabricated using DC magnetron sputtering and thermionic vacuum arc method
In this work, we discuss fabrication and characterization of MgB2 thin films obtained by sequential deposition and annealing of sandwich like Mg/B/Mg thin films on glass substrates. Mg and B films were prepared using DC ...
MgB2 superconducting thin films grown by magnetron sputtering
(National Institute of Optoelectronics, 2007-02)
In this study, we report the growth and properties of MgB2 thin films on polycrystalline Al2O3 substrates. A composite MgB2 target was produced by MgB2 and Mg powder mixing, using a hot pressing technique. MgB2 thin films ...
Instability phenomena in microcrystalline silicon films
(National Institute of Optoelectronics, 2005-02)
Microcrystalline silicon (μc-Si:H) for solar cell applications is investigated with respect to the material stability upon treatment of the material in various environments, followed by annealing. The material can be ...
