Structural and Electrical Properties of ZnO Films Deposited on GaAs Substrates by RF Magnetron Sputtering
Sputter deposition of ZnO films on GaAs substrates has been investigated. ZnO Alms were deposited using a ZnO compound target in Ar or Ar/O2 (95/5) ambient. Deposition parameters such as RF power, substrate-targe...

Erbium Doped Semiconductor Thin Films Prepared by Rf Magnetron Sputtering
Highly Er-doped (~1020 atoms/cm3) silicon and silica films were deposited by RF magnetron sputtering. Erbium was doped into the host material by co-sputtering technique. Deposited films (0.5 - 1.2 µm thick) were ...

Structural, Electrical, and Optical Properties of Erbium-Doped Epitaxial BaTiO3 Films Grown by RF Sputtering
We have investigated the epitaxial growth of Er-doped BaTiO3 films using rf magnetron sputtering. The Er-doped films (0.5 - 1 μm thick) were deposited on MgO (001) single-crystal substrates at various temperature...

Monitoring of the Surface Species on Silicon After Chemical Cleaning by FTIR Spectroscopy
For the analysis of as-cleaned surface, we have used a the unique IR method that uses a highsurface-area porous sample. We have observed by experiments that the oxide growth rate on silicon is reduced to a min...

The critical amount of nitrogen on the formation of nitrogen gas pores during solidification of 25Cr-7Ni duplex stainless steels
The effects of casting thickness, nitrogen contents, cooling rate, and Mn contents on the formation of nitrogen gas pores during solidification of 25Cr-7Ni-1.5Mo-3W duplex stainless steels (DSS) were quantitat...
