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 and graphene. The broader impact of our work ranges from solar energy harvesting to medical diagnostics.
On-going projects in 2018
- Carrier multiplication for photovoltaics: Photocurrent generation in carbon nanotube pn junctions
- Quantum phases in 1d systems: Fundamental studies of nominally-metallic carbon nanotubes
- Graphene biosensors: Flexible graphene transistors for neural recording
- Graphene supercapacitors: the electric double layer at the interface between graphene and various electrolytes
- 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.
