The influence of a silicon substrate conductivity type on the efficiency of photostimulated polyelectrolyte adsorption

Resumo

Changes in the work function of silicon substrates of different conductivity types under illumination and after deposition of a polyethylenimine layer by the method of photostimulated adsorption were examined. It is revealed that photostimulated adsorption of polyethylenimine results in the electrical passivation of silicon and its correlates with a value of the work function change under illumination.
