Formation Mechanism and Orderly Structures of an Iron Film System Deposited on Silicone Oil Surfaces

A new iron film system, deposited on silicone oil surfaces by vapor phase deposition method, has been fabricated and its formation mechanism as well as orderly structures has been studied. It is found that the formation mechanism of the films obeys a two-stage growth model, which is similar to that of the other metallic films on liquid substrates. Large and orderly structures are observed in the continuous iron films. The experiments show that the orderly spatial structures result from the local material gathering in these nearly free sustained films.
