Zusammenfassung:
Thermodynamic aspects of solids are addressed as far as
necessary for the discussion of ion transport and morphological
metastability of nano-crystalline matter. Special emphasis is
laid on the distinction between trivial and true size effects.
As far as true size effects with respect to point defect
chemistry are concerned, i.e. phenomena connected with changes
of local properties, it is meaningful to differentiate between
electrical size effects (space charge overlap) and structural
size effects. Both influence the electrochemical potential, the
former via the electrical potential term, the latter-which also
includes elastic effects-via the non-configurational part of
the chemical potential. (C) 2002 Elsevier Science B.V. All
