Cathodoluminescence of self-organized heterogeneous phases in multidimensional perovskite thin films
Published 2020“…Little is known, however, about the phase distribution and self-organization properties of multidimensional perovskite thin films. In this work, we combine steady-state and time-resolved cathodoluminescence microscopy with photoluminescence techniques and reveal with unprecedented resolution the characteristic self-assembly of heterogeneous phases of perovskites with different dimensionality, driven by uneven redistribution of methylammonium cations during film formation. …”

Interface and surface cation stoichiometry modified by oxygen vacancies in epitaxial manganite films
Published 2013“…Here, transmission electron microscopy and synchrotron-based spectroscopy are used to demonstrate that oxygen vacancies during growth serve as a critical factor for modifying the cation stoichiometry in pulsed laser deposited La0.8Sr0.2MnO3 films. Near the film/substrate (SrTiO3) interface, A-site cations (La/Sr) are in excess when oxygen vacancies are induced during film growth, partially substituting Mn. …”

Electrical and optical properties of hybrid transparent electrodes that use metal grids and graphene films
Published 2014“…The outcome of our study provides unprecedented guidelines for future design of metal grids integrated in transparent conductors. We also find that the graphene film forms an effective barrier to retard the degradation of the copper grid when the hybrid transparent conductor is heated in air up to high temperatures for an extended period of time. …”

Molecular dynamics study of confined liquid film viscosity in constant-pressure and constant-distance systems
Published 2024“…To address this disparity, we performed molecular dynamics simulations to gain insights into the mechanisms of viscosity changes in confined liquid UV-curable resin films used in nanoimprint lithography. Solid surfaces were fixed to maintain a constant pressure or distance, resembling SFA and FWM, respectively. …”

Tailoring the angular and spectral reflectance characteristics of color-dynamic films by modifying their photonic texture and topcoat roughness
Published 2024“…The model is verified with data obtained by imaging the angular scattering distribution and spectroscopic analysis of four representative combinations of photonic texture and surface coat roughness. The findings presented in this thesis validate the hypothesis that controlling texture of the photonic film and roughness of its topcoat allows for tailoring the visual appearance of structurally colored materials. …”
