Comparing Transmission- and Epi-BCARS: A Transnational Round Robin on Solid State Materials
Franz Hempel, Federico Vernuccio, Lukas König +5
Broadband coherent anti-Stokes Raman scattering (BCARS) is an advanced Raman spectroscopy method that combines the spectral sensitivity of spontaneous Raman scattering (SR) with th…
Time-domain observation of interlayer exciton formation and thermalization in a MoSe/WSe heterostructure
Veronica R. Policht, Henry Mittenzwey, Oleg Dogadov +11
Vertical heterostructures (HS) of transition metal dichalcogenides (TMDs) host interlayer excitons (ILX), with electrons and holes residing in different layers. With respect to the…
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…
Tuning the Ultrafast Response of Fano Resonances in Halide Perovskite Nanoparticles
Paolo Franceschini, Luca Carletti, Anatoly P. Pushkarev +12
The full control of the fundamental photophysics of nanosystems at frequencies as high as few THz is key for tunable and ultrafast nano-photonic devices and metamaterials. Here we…
The ultrafast onset of exciton formation in 2D semiconductors
Chiara Trovatello, Florian Katsch, Nicholas J. Borys +11
The equilibrium and non-equilibrium optical properties of single-layer transition metal dichalcogenides (TMDs) are determined by strongly bound excitons. Exciton relaxation dynamic…
Strongly coupled coherent phonons in single-layer MoS
C. Trovatello, H. P. C. Miranda, A. Molina-Sánchez +15
We present a transient absorption setup combining broadband detection over the visible-UV range with high temporal resolution (20fs) which is ideally suited to trigger and de…
Role of matrix elements in the time-resolved photoemission signal
F. Boschini, D. Bugini, M. Zonno +17
Time- and angle-resolved photoemission spectroscopy accesses the ultrafast evolution of quasiparticles and many-body interactions in solid-state systems. However, the momentum- and…
Direct observation of intravalley spin relaxation in single-layer WS
Z. Wang, A. Molina-Sanchez, P. Altmann +12
In monolayer Transition Metal Dichalcogenides (TMDs) the valence and conduction bands are spin split because of the strong spin-orbit interaction. In tungsten-based TMDs the spin-o…
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…
Probing Femtosecond Lattice Displacement upon Photo-carrier generation in Lead Halide Perovskite
Giovanni Batignani, Giuseppe Fumero, Ajay Ram Srimath Kandada +5
Electronic properties and lattice vibrations are supposed to be strongly correlated in metal-halide perovskites, due to the "soft" fluctuating nature of their crystal lattice. Thus…
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…
Ultrafast carrier thermalization in lead iodide perovskite probed with two-dimensional electronic spectroscopy
Johannes M. Richter, Federico Branchi, Franco Valduga de Almeida Camargo +4
In band-like semiconductors, charge carriers form a thermal energy distribution rapidly after optical excitation. In hybrid lead halide perovskites, the cooling of such thermal car…
Resonant optical control of the structural distortions that drive ultrafast demagnetization in CrO
Vera G. Sala, Stefano Dal Conte, Timothy A. Miller +5
We study how the color and polarization of ultrashort pulses of visible light can be used to control the demagnetization processes of the antiferromagnetic insulator CrO. W…
