description:
	Metal on semiconductor systems have attracted much attention due to novel growth modes suggested to be driven by quatum size effects. We have done  studies of magical thickness and morphology for the system Ag/Si(111). We propose this time to study a new system, Ag on Ge(111). This system, that has no been studied for QSEs although it contains intriguing properties, offers a practical advatage for us. We plan to study different film thicknesses on the same substrate. The Ge substrate will be cleaned in vacuum by argon-ion sputtering and annealing. In addition, we want to continue our work on the Ag/Si(111) system.
	Allocation of multiple 16-24hrs slots separated at least for 48 hrs will be welcomed as we want to study to different substrates.
