Atomically Traceable Nanostructure Fabrication

Special issue on atomically controlled fabrication technology

Editorial The Global Center of Excellence (GCOE) for atomically controlled fabrication technology was established in 2008 by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), as a succession program of the 21st Century COE program for atomistic fabrication technology promoted from 2003 to 2007. The GCOE program is implemented by three departments, namely the De...

Fabrication and nanostructure of oriented FePt particles

Thin films of oriented tetragonal FePt particles separated by amorphous alumina have been fabricated by electron beam evaporation. The ordering of the FePt particles without coarsening can be tailored by annealing conditions. The value of coercivity of the annealed film reached as high as 4.4 kOe. The perpendicular magnetic coercivity of the annealed film was slightly larger than in-plane coerc...

Laser Focusing of Atoms for Nanostructure Fabrication

Laser-focusing of atoms has emerged as a viable form of nanofabrication. Structures are formed by focusing chromium atoms as they deposit onto a surface. The focusing occurs in a standing-wave laser field in one or two dimensions, resulting in arrays spaced at exactly half the laser wavelength ( /2 = 212.78 nm). Atomic force, scanning electron, and transmission electron microscopies are used to...

Nickel electroplating for nanostructure mold fabrication.

We demonstrated a practical process of fabricating nickel molds for nanoimprinting. Dual-side polished glass is chosen as the substrate on which nickel nanostructures are successfully electroplated. Photonic crystal structures with 242 nm diameters and other nanoscale pillars down to 9 nm diameters are achieved over a large area. The electroplating parameters are investigated and optimized. Thi...
