EOU, thanks for the coronation, appreciated. 
The "foil effect" in my understanding accents the fact that in very thin material the role of the surface increases and the difference between surface and bulk properties is significant. It is because the surface atoms are in an asymmetric environment.
The topic is for me quite complicated. Even Wolfgang Pauli (Nobel Prize in Physics 1945) said: ‘‘God made the bulk; the surface was invented by the devil’’.
