ELECTROSYNTHESIS OF YTTRIUM CHALCOGENIDES FROM A NONAQUEOUS BATH

In recent years, there has been much interest in chalcogenide semicond uctors. Especially rare earth chalcogenides show most interesting semi conducting properties. In the present investigation, we report for the first time, the electrosynthesis of yttrium chalcogenide films on a v ariety of substrates in a non-aqueous hath, using sodium acetate as a complexing agent. The electrodeposition potentials are estimated from the polarization curves. The films are characterized by optical absorp tion, scanning electron microscope and X-ray diffraction techniques an d the results obtained have been reported.
