Abstract :
Studies of Atomic Hydrogen accumulation
in highly oriented pyrolytical graphite (HOPG) have
been performed using scanning tunnelling microscope
(STM) and atomic force microscope (AFM). It is found
that after intercalation atomic hydrogen is stored
among graphene layers in H2 gas form, captured inside
graphene blisters. On desorption of hydrogen, some
lateral etching of upper graphene layers takes place.
Significant information about intake, retention and
possibility of manifold accumulation of hydrogen in
HOPG has been found.
