Originální abstrakt

When electrons are optically excited high into the conduction band, they usually thermalize rapidly, losing energy through scattering processes. The ability to efficiently extract hot-carriers in the upper conduction band would be useful but is hampered by the lack of understanding of the processes involved. Taghinejad et al. developed a technique based on analyzing the terahertz pulses emitted by the hot-carriers (see the Perspective by Bangle and Mikkelsen). Modeling allowed them to unravel the spatiotemporal dynamics of the hot-carrier transport, providing a clearer picture for developing applications such as energy harvesting and photochemistry that can exploit these high-energy hot-carriers.
