We are an experimental physics group in the Department of Physics at Oregon State University. We investigate applied physics questions related to nanoscale systems such as carbon nanotubes, graphene and two-dimensional semiconductors. The broader impact of our work ranges from developing new sensors to understanding new quantum phenomena.

On-going projects in 2023

• Single-pixel spectrometers: We build and measure heterostructures made from two-dimensional semiconductors. The devices have a customizable, voltage-tunable spectral response.
• Quantum phases in 1d systems: We use carbon nanotubes to confine strongly-interacting electrons inside one-dimensional wires. We study the resulting many-body quantum states.
• Quantum pumps: We build hybrid quantum systems where surface acoustic waves are coupled to one-dimensional wires.
