By low temperature (145K) deposition method, we prepared such flat Pb films on the Si (111) substrate over a wide thickness range (from 10ML to 32ML). The unique growth behaviors were investigated by RHEED, STM and ARPES. A critical thickness of 10ML is established, at which the atomically flat Pb films become stable at room temperature. Between 10ML and 20ML, the growth exhibits a quasi bi-layer growth mode. Above 21ML, a layer-by-layer growth mode was observed.
