Research

My project is about the thin-film growth by molecular beam epitaxy (MBE) of topological semimetals on III-V semiconductors. These materials would be beneficial for spintronic and electronic applications which could enhance energy efficient computing, data storage and scalable quantum computing. We aim to grow quantum-confined heterostructures and investigate electrical properties.

In my research, I am focused on growing and characterizing ultra-thin InBi and TaAs films on InSb substrates. The key point is to optimize the growth parameters to achieve high-quality thin films with sharp interfaces.

Skills & Experience

I have experience using the ultra-high vacuum MBE system "Morbius", including transferring samples under ultra-high vacuum, performing in situ sample cleaning, monitoring the growth by reflection high energy electron diffraction (RHEED), running in situ X-ray spectroscopy (XPS). Also, we have vented the system and repaired cells etc. I gained hands-on UHV experience and developed troubleshooting skills.
