Author(s): Matthew R. Bergren, Brian J. Simonds, Baojie Yan, Guozhen Yue, Richard Ahrenkiel, Thomas E. Furtak, Reuben T. Collins, P. Craig Taylor, and Matthew C. Beard We report on the ultrafast carrier dynamics in hydrogenated nanocrystalline silicon (nc-Si:H) using time-resolved terahertz spectroscopy. Photoexcitation at 407 nm primarily produces charge carriers in the a -Si phase, but they undergo a rapid electron transfer to the c -Si phase prior to complete the... [Phys. Rev.
