Scientific Achievement
Researchers in the Ultrafast Materials Science program unveiled the existence of well-defined E vs k dispersion in an amorphous materials. The proposed theoretical model that goes beyond liquid metal theory can account for the observed emergence of coherence.
Significance and Impact
Showcases that, even in the absence of long-range order, a well-defined short-range real-space length scale is enough to recover electronic coherence and hence dispersive band structures in a material.
Research Details
- ARPES experiments with micro spatial resolution were carried on samples with different level of crystallinity
- Bi2Se3 samples with different levels of crystallinity were grown using UHV e-beam evaporators
