A prototypical PCM is the pseudobinary (GeTe)2-(Sb2Te3)1 or Ge2Sb2Te5 alloy. A two-year research plan to study strain engineering of Ge2Sb2Te5 evolved into something different, yet related. 04.02.2016 - Gerrit Groenhof: ”Observe while it happens: Catching photobiology in the act with computer simulations and time-resolved x-ray crystallography” Biological responses to light, as happens for instance in vision or photosynthesis, are promising paradigms for constructing molecular devices, such as motors, switches, or photo-voltaics. Mimicking such processes requires a complete understanding of the underlying molecular dynamics. As the relevant time and spatial resolution can be difficult to access experimentally, we make use of computer simulations to gain atomistic insights into these processes. We will present the results of simulations of various photoactive systems as well as their experimental validation by means of (femto-second!) time-resolved x-ray crystallography at a free electron laser. Finally, we will briefly discuss how our simulations can aid rational design of molecular devices.
