X-ray driven displacive excitation of coherent phonons

Oleg Dogadov, Rémi Claude, Christoph Emeis, Giovanni Batignani et autres

Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide limited leverage over the driving force. Here, we demonstrate coherent lattice dynamics in trigonal tellurium using free-electron laser pulses tuned to the Te …

Imide Substitution Drives the Supramolecular Assembly of Perylene Diimide Into Laterally Modulated Metallic/Semiconducting Molecular Patterns

Giacomo Agnesod, Simone Pistillo, Davide Piva, Luca Schio et autres

ABSTRACT Perylene dyes are key building blocks in organic optoelectronics and photocatalysis owing to their highly tunable electronic structure. Here, we investigate the impact of imide substitution with bulky 2,6‐isopropylphenyl (iPr) on the structural and electronic properties of perylene diimide (PDI) monolayers …

From solution to thin films: unravelling excited-state behaviour in halogenated diradicaloids

Matteo Bevilacqua, Luca Ciuffarin, Roberto Costantini, Luca Schio et autres

Stable fluorine and chlorine decorated Thiele-like diradicaloids were synthesized and studied in solution and in thin films. Femtosecond transient absorption measurements showed, for both molecules, charge-separated states in solution, but only short-lived singlets in thin films, with no evidence of twisted or …

Interfacial Charge Transfer Enhances Transient Surface Photovoltage in Hybrid Heterojunctions

Cristian Soncini, Roberto Costantini, Martina Dell’Angela, A. Morgante et autres

/p-Si(100) heterojunction has been studied in dark conditions and under illumination. The element-sensitivity of the time-resolved X-ray photoemission provides a real-time picture of the photoexcited carrier dynamics at the interface and within the film, enabling one to distinguish between substrate and molecular …

Electronic Structure and Charge Dynamics at the Tri-pyrene Boroxine–Gold Interface

Daniele Toffoli, Claudio Lentini Campallegio, Simone Pistillo, Simone Micheloni et autres

A combined theoretical and experimental study has been carried out to investigate in detail the electronic structure at the boroxine–gold interface. Tripyrene boroxine adsorbs with a flat geometry on Au(111), and the interaction is driven by dispersion forces. Near-edge X-ray absorption measurements, …

Aging effect on ▫$Ti_3C_2T_x$▫ MXene

Rokaya Osama, Lakshimi Rajan, Jurij Urbančič, Ali Shaygan Nia et autres

MXenes, the two‐dimensional class of nanomaterials consisting of transition metal carbides, nitrides, or carbonitrides, have been spotlighted in the last decade due to their peculiar properties, allowing them to be applicable in different fields, ranging from energy storage to sensors. In particular, …
