Easy fabrication of electrically insulating nanogaps by transfer printing
MetadataShow full item record
An easy and cost-effective method to reproducibly fabricate nanogaps over a large area is introduced. Gold is evaporated on low-aspect-ratio polydimethylsiloxane (PDMS) stamps at an angle of 60°. Afterwards, the stamp is brought into contact with a silicon/silicon dioxide substrate and subsequently peeled at rates varying from 1 to 3 mm s , resulting in the fabrication of nanogaps between two gold electrodes. The fabrication of insulating nanogaps with a width down to 50 nm is demonstrated. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
