Response of Polyelectrolyte Layers to the SiO2 Substrate Charging As Probed by XPS

A single layer of the cationic polyelectrolyte poly(allyamine) hydrochloride (PAH) deposited, using the layer-by-layer technique, on a silicon substrate containing 5 nm oxide layer is investigated by XPS while applying an external potential bias to the sample to control and manipulate the charge bui...
