Nanoxerography: nanostructured deposition of aerosol particles by charge printing

In English

Författare

Summary, in English

A method has been developed to transfer complex charge patterns to flat substrate surfaces, allowing nanostructured deposition of nanoparticles from the gas phase. Comparable to soft lithography, a stamp made of poly(dimethysiloxane) (PDMS), covered with a metal layer, is pressed on the surface of a silicon oxide on silicon substrate. Due to contact charging negative or positive charges are transferred from the stamp to the substrate. The process allows to create patterns with feature sizes from the millimeter range down to the sub-100 nm range during one charging procedure. After the charging process, oppositely charged monodisperse aerosol nanoparticles are deposited on the charge patterns
