3D Smith charts scattering parameters frequency-dependent orientation analysis and complex-scalar multi-parameter characterization applied to Peano reconfigurable vanadium dioxide inductors

Mihai Adrian Ionescu, Anna Krammer, Junrui Zhang, Josef Andreas Schuler, Montserrat Fernandez-Bolanos Badia, Emanuele Andrea Casu, Matteo Cavalieri, Andrei Müller

Recently, the field of Metal-Insulator-Transition (MIT) materials has emerged as an unconventional solution for novel energy efficient electronic functions, such as steep slope subthermionic switches, neuromorphic hardware, reconfigurable radiofrequency fu ...

Theoretical estimation of the linear electro-optic effect in compressively strained c-domain (Ba, Sr)TiO3 thin films using a phenomenological thermodynamic model

Nava Setter, Alexander Tagantsev

The influence of compressive strain on the linear electro-optic (EO) effect in c-domain (BaxSr1-x)TiO3 (BST) thin films was theoretically investigated using a phenomenological thermodynamic model. We considered that the c-domain BST thin films were grown o ...

On the collapsibility of measures of effect in the counterfactual causal framework

Mats Julius Stensrud, Anders Huitfeldt

The relationship between collapsibility and confounding has been subject to an extensive and ongoing discussion in the methodological literature. We discuss two subtly different definitions of collapsibility, and show that by considering causal effect meas ...

Large impact of strain on the electro-optic effect in (Ba, Sr)TiO3 thin films: Experiment and theoretical comparison

Alexander Tagantsev

(001)-epitaxial (Ba0.5Sr0.5)TiO3 (BST) thin films with different magnitudes of compressive strain were fabricated on SrRuO3/SrTiO3 substrates by pulsed laser deposition, and their electro-optic (EO) properties were characterized by modulation ellipsometry ...

Stereodynamics of Ne(3P2) reacting with Ar, Kr, Xe, and N2

Andreas Osterwalder, Sean Dennis Steven Gordon, Junwen Zou, Silvia Tanteri

Stereodynamics experiments of Ne(3P2) reacting with Ar, Kr, Xe, and N2 leading to Penning and associative ionization have been performed in a crossed molecular beam apparatus. A curved magnetic hexapole was used to state-select and polarize Ne(3P2) atoms w ...

Mode Coupling in Plasmonic Heterodimers Probed with Electron Energy Loss Spectroscopy

Jürgen Brugger, Olivier Martin, Duncan Thomas Lindsay Alexander, Jérémy Butet, Valentin Flauraud, Gabriel David Bernasconi

While plasmonic antennas composed of building blocks made of the same material have been thoroughly studied, recent investigations have highlighted the unique opportunities enabled by making compositionally asymmetric plasmonic systems. So far, mainly hete ...

Microstructure and ferroelectricity of BaTiO3 thin films on Si for integrated photonics

Patrik Willi Hoffmann, Michael Oliver Reinke, Chiara Marchiori

Significant progress has been made in integrating novel materials into silicon photonic structures in order to extend the functionality of photonic circuits. One of these promising optical materials is BaTiO3 or barium titanate (BTO) that exhibits a very l ...

Programmable chiral nanocolloids

Hyeonho Jeong

Nanoparticles promise a variety of application in energy, medicine, and biology. However, most nanoparticlesâ material composition and shape cannot be tuned and so functions have thus far been limited. Moreover they are often also chemically unstable in ...

Theory, design and measurement of near-optimal graphene reconfigurable and non-reciprocal devices at terahertz frequencies

Michele Tamagnone

This thesis explores the applications of graphene for terahertz and far infrared optical components and antennas, with particular emphasis on tunable and non-reciprocal devices. Both terahertz technologies and graphene are emerging fields which hold many p ...

Direct imaging of surface plasmon polariton dispersion in gold and silver thin films

Gaël Nardin

We image the dispersion of surface plasmon polaritons in gold and silver thin films of 30 and 50 nm thickness, using angle-resolved white light spectroscopy in the Kretschmann geometry. Calibrated dispersion curves are obtained over a wavelength range span ...
