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.
- Atomic force microscope (Asylum Research MFP3D),
- Probe station for electrical characterisation (Cascade Microtech)
- Fume hoods/wet benches for device fabrication and biology preparation.
- Electron beam evaporator for thin film deposition
- Carbon nanotube growth furnace (1 inch diameter)
- Graphene growth furnace for large-area graphene (4 inch diameter)
- Scanning photocurrent microscope with variable wavelength excitation (Fianium SC450 light source) and optical cryostat.
