Attosecond band-gap dynamics in silicon | Science

The band structure of crystalline silicon accommodates both direct and indirect excitations of electrons across the band gap (). At low intensities, a near-infrared (NIR) pump pulse can in principle promote electrons from the VB maximum across the indirect band gap ( E gap = 1.2 eV), satisfying momentum conservation by the addition of a phonon.
