Diffusion of Muonium and Hydrogen in Diamond [PDF]
Physical Review Letters, 2007 Jump rates of muonium and hydrogen in diamond are calculated by quantum transition-state theory, based on the path-integral centroid formalism. This technique allows us to study the influence of vibrational mode quantization on the effective free-energy barriers Delta F for impurity diffusion, which are renormalized respect to the zero-temperature ...

Visualization of one-dimensional diffusion and spontaneous segregation of hydrogen in single crystals of VO2 [PDF]
, 2016 Hydrogen intercalation in solids is common, complicated, and very difficult to monitor. In a new approach to the problem, we have studied the profile of hydrogen diffusion in single-crystal nanobeams and plates of VO2, exploiting the fact that hydrogen ...
