Ultrafast Lattice-Bonding Dynamics of Tellurium

Presentation Date: 

Wednesday, January 15, 2003


Ultrafast Electronics and Optoelectronics 2003 Conference (Washington, DC)

Presentation Slides: 

A pump-probe technique measuring the dielectric function is presented and applied to the ultrafast dynamics of coherent phonons in Te. Oscillations in the bonding-antibonding splitting are revealed, allowing for THz modulation of a semiconductor-semimetal transition.
