Lattice dynamics and elastic properties of black phosphorus
Eva A. A. Pogna, Alexeï Bosak, Alexandra Chumakova +4
We experimentally determine the lattice dynamics of black phosphorus layered crystals through a combination of x-ray diffuse scattering and inelastic x-ray scattering, and we ratio…
Electrically tuneable nonequilibrium optical response of graphene
Eva A. A. Pogna, Andrea Tomadin, Osman Balci +9
The ability to tune the optical response of a material via electrostatic gating is crucial for optoelectronic applications, such as electro-optic modulators, saturable absorbers, o…
Unveiling the detection dynamics of semiconductor nanowire photodetectors by terahertz near-field nanoscopy
Eva A. A. Pogna, Mahdi Asgari, Valentina Zannier +3
Semiconductor nanowire field-effect transistors represent a promising platform for the development of room-temperature (RT) terahertz (THz) frequency light detectors due to the str…
Solution processable and optically switchable 1D photonic structures
G. M. Paternò, C. Iseppon, A. D'Altri +9
In this work, we report the first demonstration of a solution processable, optically switchable 1D photonic crystal by implementing phototunable doped metal oxide nanocrystals. The…
Photo-Induced Bandgap Renormalization Governs the Ultrafast Response of Single-Layer MoS2
Eva A. A. Pogna, Margherita Marsili, Domenico De Fazio +9
Transition metal dichalcogenides (TMDs) are emerging as promising two-dimensional (2d) semiconductors for optoelectronic and flexible devices. However, a microscopic explanation of…
Valley and spin dynamics in monolayer MoS
S. Dal Conte, F. Bottegoni, E. A. A. Pogna +10
Valleytronics targets the exploitation of the additional degrees of freedom in materials where the energy of the carriers may assume several equal minimum values (valleys) at non-e…
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…
