Sample interview questions: Can you discuss any experience you have with using electron microscopy techniques in solid-state physics research?

Sample answer:

Transmission Electron Microscopy (TEM)

Characterized the atomic structure and defects in novel semiconductor materials, contributing to the development of high-performance electronic devices.
Determined the crystallographic orientation and grain boundaries in metallic alloys, correlating microstructure with mechanical properties.

Scanning Transmission Electron Microscopy (STEM)

Analyzed the chemical composition and distribution of elements in thin films and nanomaterials using energy-dispersive X-ray spectroscopy (EDS).
Imaged the electronic structure at the nanoscale using electron energy loss spectroscopy (EELS), providing insights into the electronic bandgap and bonding characteristics.

High-Resolution Scanning Transmission Electron Microscopy (HRSTEM)

Obtained atomic-scale images of crystal surfaces, interfaces, and defects, revealing the atomic arrangements and structural distortions.
Determined the atom-by-atom composition of grain boundaries and dislocations, elucidating the role of defects in material behavior.
