Solid State Physics
We have active experimental research programs in solid state physics encompassing a wide variety of semiconductors, metals, ceramics and organic materials. Several programs are joint with optics and some are interdisciplinary, involving other departments. Many faculty members are affiliated with ONAMI. There is an active weekly seminar series.
Carbon Nanotube Biosensors
Ethan D. Minotminote@physics.oregonstate.edu, (541) 737-9671, office: WNGR 417
Ethan Minot's work focuses on the development of nanoscale biosensors using semiconducting carbon nanotubes. In pursuit of single-molecule sensitivity, Ethan investigates interactions between charged molecules in aqueous solution and electron transport in single-nanotube transistor devices.

Guenter SchneiderGuenter.Schneider@physics.oregonstate.edu, (541)737-1706, office: WNGR 491
Guenter Schneider studies properties of advanced materials and systems on the nanoscale using a variety of computational methods. Current research focuses (i) on the thermodynamics of metal clusters using Monte Carlo simulations with empirical and ab-initio potentials, and (ii) the study of transport in systems with reduced dimensionality and strong correlations using a real-time approach within the density matrix renormalization group.
Organic Photonics and Electronics
Oksana G. Ostroverkhovaoksana@science.oregonstate.edu, (541)737-1679, office: WNGR 413
The Organic Photonics and Electronics Group explores light-matter interactions in organic optical materials. Of particular interest are the basic physics of exciton and photogenerated charge carrier dynamics in organic semiconductors and inorganic-organic polymer nano-composites, photophysical and electronic properties of individual molecules in studies of complex environments, and applications of organic molecules in nanoscale electronic and all-optical devices.
Computational Solid State Physics
David Roundyroundyd@physics.oregonstate.edu, (541)737-1701, office: WNGR 401B
David Roundy's work involves computation of electronic, mechanical and other properties of condensed matter systems including superconductors, nanotubes and defects in semiconductors. Currently, David is focusing on the creation of a classical density functional to describe water, and application of this approach to aqueous interfaces and systems in aqueous solution.
Femtosecond Spectroscopy in Semiconductors

Yun-Shik Lee's research focuses on terahertz spectroscopy and ultrafast carrier dynamics in semiconductors using femtosecond lasers. Major activities are (i) development of new schemes to manipulate teraherz (THz) pulses using optical rectification in nonlinear crystals (LiNbO3 , ZnTe, and GaAs), (ii) optical and THz measurements at cryogenic temperature to investigate exciton dynamics in semiconductor quantum wells (QWs) under strong THz fields, and (iii) study of large amplitude motions in proteins via THz time-domain spectroscopy (THz-TDS) investigating the feasibility of using THz spectroscopy for biosensing and analysis.
Neutron Diffraction Studies of Novel Magnetic Semiconductor Nanostructures
Tomasz Giebultowicztgiebult@physics.oregonstate.edu, (541)737-1707, office: WNGR 375
Tom Giebultowicz's research program includes studies of magnetic superlattices using neutron scattering and computational modeling.
Electronic Materials
Janet Tatetate@physics.orgeonstate.edu, (541)737-1700, office: WNGR 485
Janet Tate's research focuses on structural, transport, and optical properties of electronic materials, especially transparent conductors. Mostly, the group investigates thin films deposited by physical vapor deposition, but also studies powders and single crystals.
Density Functional Calculations of Magnetic Anisotropy
Henri Jansenphysics.chair@science.oregonstate.edu, (541)737-1668, office: WNGR 303
Henri Jansen's research is computational solid state physics. The calculations focus on the electronic structure of solids and the electronic contribution to the total energy of solids. This work relies on very precise numerical techniques for simple solids with a small number of atoms in the unit cell, but also semi-empirical techniques for large systems including defects of surfaces.
Nuclear Magnetic Resonance
William W. Warrenwwarren@physics.orgeonstate.edu, (541)737-4024, office: WNGR 313
William Warren's research involves application of nuclear magnetic resonance (NMR) and optical techniques to a variety of problems in condensed matter physics including transparent conductors and defects in semiconductors.
