Persistent enhancement of exciton diffusivity in CsPbBr3 nanocrystal solids
In semiconductors, exciton or charge carrier diffusivity is typically described as an inherent material property. Here, we show that the transport of excitons among CsPbBr3 perovskite nanocrystals (NCs) depends markedly on how recently those NCs were occup ...
Amer Assoc Advancement Science2024Gas/Surface reactions probed by reflection absorption infrared spectroscopy
In my thesis, I present an investigation of the dissociation reactions of gas phase molecules on single crystal metal surfaces studied by a molecular beam in combination with Reflection Absorption Infrared Spectroscopy (RAIRS). Two gas/surface systems were ...
EPFL2023Non-classical photon-phonon correlations at room temperature
With the development of quantum optics, photon correlations acquired a prominent role as a tool to test our understanding of physics, and played a key role in verifying the validity of quantum mechanics. The spatial and temporal correlations in a light fie ...
EPFL2021Quantum state and surface-site-resolved studies of methane chemisorption by vibrational spectroscopies
Rainer Beck, Ana Gutiérrez González
The combination of quantum state-specific reactant preparation by infrared laser pumping with surface-site-resolved detection of chemisorbed reaction products by Reflection Absorption Infrared Spectroscopy (RAIRS) enables highly detailed studies of molecul ...
2020Bond-selective and surface-site-specific dissociation of methane on platinum
I present a molecular beam study of methane dissociation on differ-ent surface sites of several platinum single crystal surfaces (Pt(111), Pt(211), Pt(210), Pt(110)-(2x1)). The experiments were performed in a molecular beam/surface-science apparatus that c ...
EPFL2019Scattering HCl Molecules from Au(111) and Ag(111) Surfaces
In this thesis, I present an experimental molecular beam surface scattering study of dynamical processes involved when HCl molecules are scattered from Au(111) and Ag(111) surfaces. I investigated vibrational excitation, translational inelasticity and diss ...

Michele Ceriotti, Venkat Kapil
Metal–organic frameworks show both fundamental interest and great promise for applications in adsorption-based technologies, such as the separation and storage of gases. The flexibility and complexity of the molecular scaffold pose a considerable challenge ...
2019Site Selective Detection of Methane Dissociation on Stepped Pt Surfaces
Rainer Beck, Ana Gutiérrez González
We report a combined experimental and theoretical study comparing methane dissociation on three di erent platinum surfaces Pt(111), Pt(211), and Pt(110)-(1 × 2). Re ection absorption infrared spectroscopy (RAIRS) was used to detect chemisorbed methyl speci ...
2019Bond selective dissociation of methane (CH3D) on the steps and terraces of Pt(211)
Rainer Beck, Ana Gutiérrez González, Fleming Crim
The dissociative chemisorption of singly deuterated methane (CH3D) has been studied on the steps and terraces of a Pt(211) surface by quantum state resolved molecular beam methods. At incident translational energy (Et) below 50 kJ/mol, CH3D dissociates onl ...
