Abstract
Ultrastable glasses produced by physical vapour deposition are fascinating materials that can mimic the properties of glasses that have been aged for thousands or millions of years.  We use physical vapour deposition to make stable glass films of oligomeric styrene. These materials exhibit exceptional stability, and offer a unique degree of tunability. We will discuss a number of studies based on these materials including enhanced mechanical properties, and how we can use isothermal rejuvenation to probe depth dependent dynamical properties of glassy films.
