Variables used for the calculation of the structure factor amplitude. Left-hand side: the liquid's layer positions dm away from the centre of the gap, dk away from the outmost mica unit cell centre and c the mica unit-cell height are indicated with arrows. Right-hand side: the number of mica unit cells in each mica membrane is N3. The gap width D is defined as the distance between the surface potassium ions of the opposing mica crystals. |
