Pt nanowires on Ge (001)
Oguzhan Gurlu and a group of scientists from University of Twente, Netherlands report about formation of Pt nanowires on Ge (001). Pt atoms adsorbed onto Ge(001) surface form extremely well-ordered nanowire arrays by self-organization after high-temperature annealing. Using scanning tunneling spectroscopy and microscopy, authors show that they are metallic and defect free. Nanowires are only 0.4 nm thick with a spacing of 1.6 nm in between, and have aspect ratios up to 1000. (Updated*)
