Charge photogeneration in few-layer MoS2
Tetiana Borzda, Christoph Gadermaier, Natasa Vujicic +12
The two-dimensional semiconductor MoS2 in its mono- and few-layer form is expected to have a significant exciton binding energy of several 100 meV, leading to the consensus that ex…
Mode-matching in multiresonant plasmonic nanoantennas for enhanced second harmonic generation
Michele Celebrano, Xiaofei Wu, Milena Baselli +10
Boosting nonlinear frequency conversion in extremely confined volumes remains a key challenge in nano-optics, nanomedicine, photocatalysis, and background-free biosensing. To this…
High energetic excitons in carbon nanotubes directly probe charge-carriers
Giancarlo Soavi, Francesco Scotognella, Daniele Viola +4
Theory predicts peculiar features for excited-state dynamics in one dimension (1D) that are difficult to be observed experimentally. Single-walled carbon nanotubes (SWNTs) are an e…
Witnessing the formation and relaxation of massive quasi-particles in a strongly correlated electron system
Fabio Novelli, Giulio De Filippis, Vittorio Cataudella +17
The non-equilibrium semiconductors physics is based on the paradigm that different degrees of freedom interact on different timescales. In this context the photo-excitation is ofte…
