Schematics of the ultrafast broadband terahertz excitation and polarization rotation detection of phonon in WSe2. Obtained result (lower right) includes the coherent phonon oscillation signal excited ...
Researchers have demonstrated a new method to calculate excitation energies. They used a new approach based on density functional methods, which use an atom-by-atom approach to calculate electronic ...
