WebJun 8, 2024 · The PTE in graphene is attributed to the hot carriers behavior. 184, 186, 189 This is different from conventional PTE induced by lattice heating. 190, 191 Hot carriers excited ultrafast by radiation can remain at a temperature higher than the lattice temperature for many picoseconds, and reach equilibrium with the lattice through electro ... WebFeb 27, 2024 · At the moment, the answer to the question which material is best suited for ultrafast chip integrated communication systems is still open. In this manuscript we report on ultrafast graphene photodetectors with a bandwidth of more than 76 GHz well suitable for communication links faster than 100 GBit s −1 per channel. We extract an upper value ...
