Samuel Lara Avila

Senior Researcher at Quantum Device Physics

Im interested in bridging basic and applied nano research. In our lab we produce new low-dimensional materials & systems to study their physical properties, looking for new discoveries, and use them to develop new applications.

Our Lab is equipped with state-of-the-art infrastructure for material (epitaxial) growth, and cryogenic magneto transport experiments. We also benefit from access to fantastic cleanroom facilities at Chalmers, extraordinary collaboration with other labs (including MAX IV synchrotron), and interaction with several companies.
