2-D THz spectroscopy of electronic dynamics in narrow-band semiconductors

Probing ballistic electrons and band curvatures with THz spectroscopy

The so-called “band structure” of solid-state materials determines how electrons move through them, and is often critical in understanding an even manipulating their conductive properties.  Scientists at ETH Zurich have demonstrated a new method applying low-frequency electromagnetic pulses to drive electrons in a “ballistic” regime, using them to measure subtle features of the band structure.
