Biomolecules perform fascinating functions essential for all life forms, including disease states upon perturbation or mutation. In order for existing biomolecular complexes to achieve optimal performances or to engineer new ones to execute targeted activities, a deep “bottom-up” understanding of the connection between the fundamental molecular mechanism and biological functions is required.

Observing the vibrational spectra of biomolecules in real time offers the exciting possibility to track ultrafast structural dynamic changes of the photoexcited chromophore if by stimulated Raman, or conformational dynamics of protein residues if extending into the IR regime and going multidimensional.

The terahertz (THz) electromagnetic wave frequency range - broadly defined as 0.1 – 30 THz (3 mm – 10 µm wavelength) - is at the interface of modern electronics and optics. This electromagnetic spectrum has been much less explored and has been called the “terahertz gap” due to the lack of efficient, room-temperature sources and detectors. Despite these difficulties, there has been recent explosion of interest in using THz pulse to address many questions in electrical engineering, physics, chemistry, and material sciences.

One of the most important aspects of contemporary semiconductor physics is an understanding of charge conduction process. Terahertz (THz) spectroscopy provides a non-contact electrical probe, thus circumvents many constraints of conventional electrical measurement techniques. In this light, I will discuss two exemplary applications of THz spectroscopy:
1. Dirac Fermion dynamics in graphene
2. Electronic transport dynamics in quantum cascade lasers
