Illustration of surface diffusion of atoms, with the blue arrows showing quantum-tunneling diffusion (through classical barriers) and the black arrow showing thermal hopping.

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

Researchers have obtained the first direct observations of atomic diffusion inside a bulk material. The research could be used to give unprecedented insight into the lifespan and properties of new ...

Researchers have recast diffusion in multicomponent alloys as a sum of individual contributions, called 'kinosons.' Using machine learning to compute the statistical distribution of the individual ...

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.

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.

The self-diffusion processes can easily damage structural integrity and compromise functions. In the manufacturing of single-atom transistors, atomic-scale patterns on semiconductors could decompose ...
