The effect of illumination on the parameters of the polymer layer deposited from solution onto a semiconductor substrate

The effect of illumination on the thickness and roughness of monolayers of polycationic molecules of polyethyleneimine deposited from solution onto a silicon substrate was discovered and investigated. The super-bandgap illumination of the substrate during polyethyleneimine adsorption causes a decrease in both the roughness and integral thickness of the organic layer on $n$- and $p$-Si substrates.
