WebJul 9, 2012 · We investigate the energy relaxation of hot carriers produced by photoexcitation of graphene through coupling to both intrinsic and remote (substrate) surface polar phonons using the Boltzmann equation approach. We find that the energy relaxation of hot photocarriers in graphene on commonly used polar substrates, under … WebFeb 18, 2024 · The changing trend of the photocarrier transfer efficiency, as a function of GO bandgap, was in good agreement with that for PL enhancement in tri-layer heterostructures . Moreover, compared to the layer-dependent stacking way of pentacene (figures 2 (c) and (d)), changing the energy offset of top layer GO was a better way to modulate the ...
WebPhotocarrier recombination can be inhibited by building potential gradients in the photoelectrode with heterojunctions. However, despite the achieved progress, only a small amount of photocarriers can be collected and take PEC reactions. One of the main reasons is that the potential gradient provided by heterojunctions is limited in the ... WebQuantitatively elucidating photocarrier dynamics mediated by trap states in perovskites is crucial for establishing a structure–performance relation and understanding the interfacial photocarrier transport mechanism. Here, trap-state-mediated photocarrier dynamics in defect-rich CsPbBr3 microplates are noninvasively investigated by ultrafast laser …
