Electrical conduction in (Ba, Sr)TiO3 thin film MIS capacitor under humid conditions
(2001)
Barium strontium titanate (BST) thin films are made on n-type Si substrate by the sol–gel technique to study electrical conduction in a metal–insulator– emiconductor (MIS) device under humid conditions. These films are ...
Measurement of tilt of a diffuse object by doubleexposure speckle photography using speckle fanning in a photorefractive BaTiO3 crystal
(2001)
A technique has been proposed for the measurement of tilt of a diffuse object using speckle fanning in a photorefractive BaTiO3 crystal. Free space geometry has been used for recording in which the axis of rotation of the ...
Giant magnetoresistance in Cu–Co films electrodeposited on n-Si
(2001)
High quality Cu–Co alloy films with excellent metallic luster have been electrolytically deposited directly onto n-Si (1 0 0) substrate, thereby eliminating the need of a conducting seed layer, which is otherwise required ...
Optical and structural properties of nanocrystalline copper oxide thin films prepared by activated reactive evaporation
(2001)
Nanocrystalline Cu O thin films have been synthesized using an activated reactive evaporation technique.Structural and optical 2 characterizations of these films have been carried out using: glancing angle X-ray diffractometer; ...
Wavelength-division multiplexing isolation filter using concatenated chirped long period gratings
(2001)
We propose the use of concatenated chirped long period gratings as an efficient wavelength-division multiplexing (WDM) isolation filter. The proposed filter not only works in the transmission mode but also has almost ...
Preparation and characterization of lead lanthanum zirconate titanate (PLZT) thin films using an organic self-assembled monolayer template
(2001)
PLZT films in peroveskite phase have been prepared by sol–gel processing. It has been observed that the use of organic self-assembled monolayer (SAM) templates improves the crystallization characteristics and lowers the ...
Photoluminescence and Raman study of porous silicon synthesized by visible and infrared laser etching
(2001)
Visible and infrared lasers have been used to photochemically fabricate photoluminescent porous silicon thin films on n-type silicon substrates. Photoluminescence measurements on porous silicon exhibit a two-peak structure ...
The observation of oscillatory behaviour in swift heavy ion irradiated quasicrystals
(2001)
The effect of 835 MeV Kr irradiation at 90 K on a stable icosahedral quasicrystal (Al65Cu25Fe5V5) is discussed here. A Kr-beam of this energy was chosen in order to keep the stopping power 1300 eV/Å in accordance with our ...
Giant magnetoresistance and magnetic properties of electrodeposited Cu–Co granular films
(2001)
Cu–Co granular films have been prepared by galvanostatic dc electrodeposition in a single sulphate bath. The magnetoresistance ratio (MR5h(R 2R ) /R j3100) increased with increase in annealing temperature until 4508C, ...
Formation of highly oriented GeBiSe films from the as-deposited amorphous state by annealing
(2000)
As-deposited amorphous GeBiSe films were crystallized by thermal and laser annealing. Their structural properties were
studied using a glancing angle X-ray diffractometer GAXRD and a transmission electron microscope TEM . ...
