Solar Energy

Due to its potential to meet the entire global energy demand, solar energy has been widely investigated as an alternative to fossil fuels.  In photosynthesis, nature has developed a mechanism for using light from…

Metal Oxides

When illuminated by UV light, a titanium dioxide electrode has been shown to catalyze water oxidation.1  Dye-sensitized solar cell (DSSC) research has led to progress in shifting the absorption of TiO2…

THz Optical Activity

Molecular chirality is an important characteristic of many biological systems and is therefore of great interest in biochemical and pharmaceutical research. Examples of chiral systems include amino acids, sugars, proteins, and enzymes. While biomolecules have mainly been studied in solution…

Organic Molecular Crystals

Vibrational spectra of molecular crystals contain intermolecular modes that are not present in other phases. These vibrations typically occur at frequencies in the THz range and are very sensitive to the nature of the crystal lattice; these spectral features can be used to differentiate…

Computational Modeling

Ab initio modeling of vibrational modes in the THz region is a challenge regardless of the material being studied. Low-frequency vibrations have soft potential energy surfaces; these cannot be accurately investigated unless the interatomic forces remaining in the system after a…
