A study of the Pb/AI (100) interfacial energy
Pb crystallites have been equilibrated on an Al (100) single-crystal substrate in ultrahigh vacuum at 590 K. The contact angle Pb crystallites has been measured to be 41.1 +/- 0.8 deg. Auger electron spectroscopy shows that 1.77 monolayers (MLs) of Pb are adsorbed on the Al substrate. By using a multilayer ...
