Abstract:

Nowadays, aberration-corrected transmission electron microscopy enables the recording of materials at atomic resolution, and focused electron beams (e-beams) are routinely used in lithographic nanofabrication processes. From a macroscopic perspective, the radiolytic processes are reasonably well understood and mainly regarded as unwanted destructive side-effects during the imaging process. However, these “side-effects” can also be regarded as a synthetic tool if the molecular-level radiation chemistry is adequately understood. Via single-molecule atomic resolution time-resolved electron microscopy (SMART-EM) techniques, we study chemical events to describe the visual observations with chemical rationale. With this, we are particularly interested if the microscopic information can be correlated to the accumulated knowledge from classical chemistry and how it can be applied to become a valuable tool for the organic chemist.
