The dynamics of hot phonons in supported, suspended,and gatedmonolayer graphene was studied by using time-resolved anti-StokesRaman spectroscopy. We found that the hot phonon relaxation is dominatedby phonon–phonon interaction in graphene, and strongly affectedby the interaction between graphene and ...
structure (TR-XANES) measurements [39]. The nonlinear-optical measurements featuring ultrafast pump-probe spectroscopy are also a common tool to investigate hot-electron dynamics in plasmonic systems as will be discussed below, allowing to extract electron and phonon temperatures as well as a contribut...

Graphene provides a platform in which the flow of charge alone is sufficient for Cˇ erenkov radiation, eliminating the need for accelerated charge particles in vacuum chambers and opening up an opportunity for the study of the Cˇ erenkov effect (Cˇ E) and its applications, especially as ...

To understand the mechanism behind the bottleneck effect observed in lead-halide perovskites, we first review some general understandings of carrier-phonon dynamics in solid-state polar semiconductors. The carrier thermalization is accompanied by the emission of LO phonons, which then decay to the low...
