Wanted: Info about crystal surface



      Dear networker !
   I have two questions about calculating of crystal surfaces.
 1). Is somewhere on network discussion list about calculation and
 measurement of crystal surface energy, and properties of molecules
 lying on the surface?
 2). Does anybody know how to calculate which lattice points belongs to
 lattice plane of given Miller indices.
          With regards
