ABSTRACT
The ejection dynamics of nanometer-thick liquid (isopropanol) films from a substrate caused by a phase transition in a superheated layer at the interface are studied. A nanosecond laser pulse is used to heat the substrate and as a result of heat transfer the fluid adjacent to the surface partially reaches a metastable state. Reflectivity and scattered light measurements demonstrate that the liquid is ejected as an intact layer which redeposits on the time scale of a few hundred nanoseconds. Measurements of the ejection dynamics are shown to be a sensitive method to obtain information about the phase transition, such as the relevant time scales and the generated pressure.

    Infrared spectroscopy is often used to monitor the formation of the perovskite phase during the preparation of lead zirconate titanate (PZT) thin films and fibres and also to detect phase transitions. Infrared spectroscopy has rarely been used to investigate bulk samples or thick films of PZT....
