Jan Schroers from Yale, a member of the research team, shares his surprise at the discovery that “atomic diffusion is capable, atom by atom, to produce these very long nanowires”. As the properties of ...

"This is the first observation of hydrogen-atom tunneling diffusion on an ice surface," coauthor Naoki Watanabe, Professor at Hokkaido University, told Phys.org.

Direct Observation of Dopant Atom Diffusion in a Bulk Semiconductor Crystal Enhanced by a Large Size Mismatch. Physical Review Letters, 2014; 113 (15) DOI: 10.1103/PhysRevLett.113.155501; ...

Researchers have demonstrated that by using argon plasma, metal atoms can be dispersed and guided to desired positions. This ...

Therefore, any jump that an atom makes contributes to diffusion and the problem becomes a lot easier to solve. "We call those jumps kinosons, for little moves," Trinkle says.

Atoms that construct atomic-scale patterns are usually accompanied by a very low atom diffusion barrier. The self-diffusion processes can easily damage structural integrity and compromise functions.
