A novel hybrid pulsed laser deposition/metalorganic vapour deposition method to form rare-earth activated GaN
A novel low-temperature method based on a combination of pulsed laser deposition and metalorganic chemical vapour deposition was used to fabricate GaN thin films doped with rare-earth (RE) ions. The films were deposited on GaN/Al2O3 substrates. The x-ray diffraction analysis of these GaN : RE (RE = Eu, Tb) samples showed that the films have the hexagonal phase of GaN and are polycrystalline wit...
متن کاملA Novel Method to Chromatographically Resolution Of Sulphonamides By Vapour-Programmed Thin-Layer Chromatography
Identification, especially of drugs, plays an important role in pharmaceutical analysis. Thin-layer chromatography (TLC) has been widely applied in this field, but sometimes its resolving power leaves something to be desired. Barbiturates, steroids, sulphonamides and local anaesthetics, for example, represent classes where an abundance of closely similar derivatives are available. Separations a...
متن کاملLeast – Squares Method For Estimating Diffusion Coefficient
Abstract: Determination of the diffusion coefficient on the base of solution of a linear inverse problem of the parameter estimation using the Least-square method is presented in this research. For this propose a set of temperature measurements at a single sensor location inside the heat conducting body was considered. The corresponding direct problem was then solved by the application of the ...
متن کاملLEAST – SQUARES METHOD FOR ESTIMATING DIFFUSION COEFFICIENT
Determining the diffusion coefficient based on the solution of the linear inverse problem of the parameter estimation by using the Least-square method is presented. A set of temperature measurements at a single sensor location inside the heat conducting body is required. The corresponding direct problem will be solved by an application of the heat fundamental solution.
متن کاملGold catalytic Growth of Germanium Nanowires by chemical vapour deposition method
Germanium nanowires (GeNWs) were synthesized using chemical vapor deposition (CVD) based on vapor–liquid–solid (VLS) mechanism with Au nanoparticles as catalyst and germanium tetrachloride (GeCl4) as a precursor of germanium. Au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in Au colloidal s...
