Re: Regarding EFM

Dear Sir, Thanks for reply. I could not understand why does Au get attract? If surface is too rough (~150 nm) with holes is there a way to collect EFM in a precise way? Thanks and regards, Gangaiah

Regarding EFM

We deposited 80 nm thick gold film on a glass substrate and made a 6 um scratch. We carried out EFM at the gap. We observed that glass region looked more darker in both positive and negative biasing (+/-1V) with 120 nm lift height. Au film is a smooth and continuous film with out any Au nanoparticles. As per my knowledge we should not observe any contrast
