Super-diffusion of excited carriers in semiconductors

Autor: Ebrahim Najafi, Vsevolod Ivanov, Ahmed Zewail, Marco Bernardi

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-7 (2017)

Determining the spatial dynamics of excited carriers will provide a more complete understanding of ultrafast carrier dynamics in materials. Using scanning ultrafast electron microscopy, Najafiet al. are able to observe the spatiotemporal dynamics of

Ultrafast dynamics. Four-dimensional imaging of carrier interface dynamics in p-n junctions

Autor: Ebrahim, Najafi, Timothy D, Scarborough, Jau, Tang, Ahmed, Zewail

Publikováno v: Science (New York, N.Y.). 347(6218)

The dynamics of charge transfer at interfaces are fundamental to the understanding of many processes, including light conversion to chemical energy. Here, we report imaging of charge carrier excitation, transport, and recombination in a silicon p-n j
