The results show that the phase shifts are different between high temperature and room temperature, and between ultrahigh vacuum and ambient and between in situ and ex situ although the morphologies are almost invariable.

文摘The morphology and phase shift of phase-separated PMMA/SAN thin film on silicon wafer were studied by in situ AFM with hot stage through the annealing and quasi-quenching. The results show that the phase shifts are different between high temperature and room temperature, and between ultrahigh vacuum and ambient and between in situ and ex situ although the morphologies are almost invariable. The reasons were discussed simply.
