How can we explain the shift of photocurrent potential onset in negative direction with increase of number of CdS SILAR deposition cycles on ZnO mesoporous anode? What to-date nanostructured semiconductors' band theory is appropriate in this case?
Please, first you can reading Wiley VHC , Riidiger Memming by titelSemiconductor Electrochemistry. Its very clear.
I need to prepare dry amylopectine powder from potatoe starch. Centrifugation seems to be the most appropriate way. Should I use any sedimentation agent to precipitate it conveniently?
