Exciton–exciton annihilation and biexciton stimulated emission in graphene nanoribbons
Autor: Giancarlo Soavi, Stefano Dal Conte, Cristian Manzoni, Daniele Viola, Akimitsu Narita, Yunbin Hu, Xinliang Feng, Ulrich Hohenester, Elisa Molinari, Deborah Prezzi, Klaus Müllen, Giulio Cerullo
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-7 (2016)
Graphene nanoribbons confine electrons to just one dimension and this gives rise to strong electron–hole interactions. Here, the authors investigate the creation and recombination of biexcitons in these structures by ultrafast optical pulses using
