Current Research Topics:


The Goncharova group works in several research areas:
1. Ion scattering: technique development and enhancement of detection in ion scattering.
2. Growth of ultra-thin films and nanomaterials using atomic layer deposition systems and molecular beam epitaxy.
3. Development of optical and electrical characterization approaches for nanomaterials.
