Abstract: C09.00005 : Honey, I Shrunk the Synchrotron: Electron Microscopy in Condensed Matter Physics*
5:24 PM–6:00 PM
In this talk, I will present few examples of how we are utilizing the new MAC-STEMs to study the thermal, optical and electronic properties of materials. In the first example, I will present our efforts in study the optical response of aperiodic nano-fabricated structures that locally (~ 1000 nm) are the same but at larger scales are translational invariant. I will also show how we can reveal the spatial range of electron-optical coupling of moire potentials in twisted graphene multilayers. Finally, I will discuss our efforts in measuring the limits of thermal property measurements using electron energy-loss spectroscopy (EELS) from cryogenic to room temperatures .
