   5# Surface Science from RS — Materials / B15 Depth
   6
   7Surface science studies interfaces between phases.
   8In RS: surface energy = J(surface_atoms/bulk_atoms) at the canonical band.
   9
  10Five canonical surface phenomena (adsorption, desorption, surface diffusion,
  11surface reconstruction, surface segregation) = configDim D = 5.
  12
  13Surface adsorption: phi-ladder at rung k gives coverage θ(k) = 1 - φ^(-k).
  14
  15Lean: 5 phenomena.

  17Lean status: 0 sorry, 0 axiom.
