Overview
Functional nanoparticles are being considered the building blocks of potential micro and nano-scale electronic, optoelectronic devices and gas sensors. Fabrication of nanoparticle-based devices would require accurate alignment of nanoparticles in specific locations.Methods for aligning nano-particles with an electric field in a charge-patterned substrate are known. However, the gas-phase patterning of nanoparticles on a charge-patterned substrate is difficult because i) the charge patterns are relatively unstable and change during the deposition process, ii) the metal-coated polymer stamp is easily damaged in the charging process, and iii) the necessity of using an insulated surface on the substrate limits its application especially on metal-semiconductor devices.
Researchers at the University of Maryland have developed a new assembly method to position nanoparticles deposited from the gas phase onto substrates using the electrostatic force generated by biased p-n junction substrates.
