Charge accumulation and frequency characteristics of sequential tunneling.
This paper, as an addendum to Phys. Rev. B 46, 4714 (1992), provides a study of the finite frequency spectrum of noise current in sequential tunneling through double-barrier structures and the effect of space-charge accumulation
Using ultrafast optical-pump terahertz-probe spectroscopy, we study the THz dynamics and electronic cooling in few-layer epitaxial and CVD graphene; a microscopic theory of carrier-carrier and carrier-phonon interactions accounts quantitatively for the observed dynamics.
