description:
	It has been shown that the morphology of ultrathin films of Pb on
	Si(111) grown at low T is greatly influenced by electronic effects.
	In particular, certain "magic" thicknesses appear to be energetically
	more favorable than others.  These magic thicknesses are temperature
	dependent and seem to roughly differ in bilayers.  This experiment
	would map out the phase space of this system with the aim of
	determining how QSE affects the energy landscape of the system.
	
	Please break up time into two chunks of 2-3 days each separated by at
	least 3 days.  Thanks.
