Scientists reveal role of neighboring adsorbates and quantum tunneling in surface diffusion of hydrogen atoms

A research group led by Prof. Yang Yong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has revealed the role of neighboring adsorbate and quantum tunneling in the diffusion of hydrogen on a graphene surface, which opens a possible way for ultrahigh precision measurement based on atomic systems, in particular, exploring the existence of a minimum length.
