Abstract
Experimental study of the hydrogen coverage of a nanoporous silicon-specific surface reveals a fractal nature of the surface of silicon nanocrystallites constituting the porous layer. A fractal model describing the nanocrystallite morphology is elaborated. The evolution of the nanocrystallites’ fractal dimension along with porosity is deduced from a correlation of the model to the experimental measurements of hydrogen concentration.
