Rapid thickness reading of CH3NH3PbI3 nanowire thin films from color maps

László Forró, Bálint Náfrádi, Claudio Grimaldi, Endre Horvath, Massimo Spina

Hybrid halide perovskite photovoltaic materials show a remarkable light conversion efficiency in various optoelectronic devices. In the fabrication of these solar cells, light emitting diodes, laser and photodetector prototypes the thickness of the perovsk ...

Electrical conduction of photo-patternable SU8-graphene composites

László Forró, Arnaud Magrez, Claudio Grimaldi, Andrea Pisoni, Maryam Majidian

Graphene-based SU8 nanocomposite is developed as a new conductive polymer, which benefits from remarkable electrical conductivity of graphene, along with photo-pattern-ability and transparency of SU8. Well defined structures with minimal resolution of 10 m ...

Large polaron formation induced by Rashba spin-orbit coupling

Claudio Grimaldi

Here the electron-phonon Holstein model with Rashba spin-orbit interaction is studied for a two-dimensional square lattice in the adiabatic limit. It is demonstrated that a delocalized electron at zero spin-orbit coupling localizes into a large polaron sta ...

Quantifying the information impact of future searches for exoplanetary biosignatures

Claudio Grimaldi

One of the major goals for astronomy in the next decades is the remote search for biosignatures (i.e., the spectroscopic evidence of biological activity) in exoplanets. Here we adopt a Bayesian statistical framework to discuss the implications of such futu ...

Signal coverage approach to the detection probability of hypothetical extraterrestrial emitters in the Milky Way

Claudio Grimaldi

The lack of evidence for the existence of extraterrestrial life, even the simplest forms of animal life, makes it is difficult to decide whether the search for extraterrestrial intelligence (SETI) is more a high-risk, high-payoff endeavor than a futile att ...

Tuning the color of high-karat gold in Au-TiO2 nanoparticle composites all the way to black

László Forró, Andrzej Sienkiewicz, Endre Horvath, Claudio Grimaldi, Lidia Rocoffort de Vinnière

For centuries, artisans have harnessed gold nanoparticles to imbue their creations with the vibrant hues that captivate the eye through interactions with visible light. In modern times, these distinct optoelectronic characteristics have pivoted toward the ...

Electrical conductivity of multi-walled carbon nanotubes-SU8 epoxy composites

László Forró, Arnaud Magrez, Claudio Grimaldi, Richard Gaal, Marijana Mionic Ebersold

We have characterized the electrical conductivity of the composite which consists of multi-walled carbon nanotubes dispersed in SU8 epoxy resin. Depending on the processing conditions of the epoxy (ranging from non-polymerized to cross-linked), we obtained ...

Upper bounds on technoemission rates from 60 years of "silence"

Claudio Grimaldi

The lack of detection to date of electromagnetic technosignatures implies either that we have been unable to detect them due to incomplete sampling of the search space or that we cannot detect them because the Earth has been located during the entire histo ...

High-Voltage Sensitivity Studies of Model Thick-Film Resistors

Thomas Maeder, Peter Ryser, Claudio Grimaldi, Caroline Marguerite Jacq, Niklaus Johner

In this work we seek to better understand the mechanisms governing pulse voltage trimming in disordered conductor-insulator composites. Therefore, we investigate the effect of the composition of thick-film resistors (TFRs) on sensitivity to high voltage pu ...

A birth-death-migration model for life in astrophysical environments

Claudio Grimaldi

To assess the number of life-bearing worlds in astrophysical environments, it is necessary to take the intertwined processes of abiogenesis (birth), extinction (death), and transfer of life (migration) into account. We construct a mathematical model that i ...

Piezoresistivity and tunneling-percolation transport in apparently nonuniversal systems

Peter Ryser, Claudio Grimaldi, Niklaus Johner

We formulate a generalized tunneling-percolation model that describes the electrical properties of conductor-insulator cellular disordered systems. This model predicts and explains the experimentally observed universal and nonuniversal behaviors of such pr ...
