Piezoelectric and elastic properties of Al0.60Sc0.40N thin films deposited on patterned metal electrodes

Federico Peretti, Luis Guillermo Villanueva Torrijo, Silvan Stettler, Marco Liffredo, Nan Xu

Sc-doped aluminum nitride (AlScN) allows for piezoelectric devices with large electromechanical coupling and the benefits increase with larger Sc doping in the film. However, with a larger Sc concentration, the process window narrows, and it is necessary t ...

Atomic-scale Characterization of Strain and Gate effects on Two-dimensional Materials by Scanning Tunneling Microscopy

Jz -Yuan Juo

Strain is an inevitable phenomenon in two-dimensional (2D) material, regardless of whether the film is suspended or supported. Moreover, strain is known to alter the physical and chemical properties, such as the band gap, charge carrier effective masses, d ...

Drops on the Underside of a Slightly Inclined Wet Substrate Move Too Fast to Grow

François Gallaire, Pierre-Thomas Paul Brun, Pier Giuseppe Ledda

Pendant drops suspended on the underside of a wet substrate are known to accumulate fluid from the surrounding thin liquid film, a process that often results in dripping. The growth of such drops is hastened by their ability to translate over an otherwise ...

Quantification of Synthetic Polyesters from Biodegradable Mulch Films in Soils

Stephanie Christa Remke

Soil biodegradable mulch films composed of the polyester polybutylene adipate-co-terephthalate (PBAT) are being increasingly used in agriculture. Analytical methods to quantify PBAT in field soils are needed to assess its soil occurrence and fate. Here, we ...

Bretherton's buoyant bubble

John Martin Kolinski, Wassim Dhaouadi

When a buoyant bubble is inserted into a closed capillary that is slightly smaller than the capillary length, it appears stuck; exactly why this is so is a puzzle that has remained unanswered over the past 50 years. Recent calculations suggest that the bub ...

Covalent polymer network semiconducting thin-films and method for producing thereof

Kevin Sivula, Liang Yao

A method for manufacturing a semiconducting, organic, covalent polymer network thin film is disclosed, said method comprising the steps of deposing a solution comprising azide- containing monomers and electron-deficient alkyne-containing monomers onto a re ...

Digital transformation and open innovation ecosystems in the tilm industry: the case of the Movieday platform

Christopher Tucci, Gianluigi Viscusi

Digital technologies are transforming the film industry. Up until roughly a decade ago, the business model for film exhibition was based on theatrical release in combination with television sales and home cinema releases (video and DVD). Recently, many que ...

Three-dimensional Rayleigh–Taylor instability under a unidirectional curved substrate

François Gallaire, Pierre-Thomas Paul Brun, Gioele Mariano Nicolò Balestra, Nicolas Igor Jacques Kofman

We investigate the Rayleigh–Taylor instability of a thin liquid film coated on the inside of a cylinder whose axis is orthogonal to gravity. We are interested in the effects of geometry on the instability, and contrast our results with the classical case o ...

Engineering reversible elasticity in ductile and brittle thin films supported by a plastic foil

Stéphanie Lacour, Nicolas Vachicouras, Christina Myra Tringides

Reversible deformation is a unique property of elastic materials. Here, we design and fabricate highly stretchable multilayered films by patterning Y-shaped motifs through films of non- elastic materials, e.g. plastics, metals, ceramics. By adjusting the g ...

An updated three-zone heat transfer model for slug flow boiling in microchannels

John Richard Thome, Mirco Magnini

This work proposes a novel physics-based model for the fluid mechanics and heat transfer associated with slug flow boiling in horizontal circular microchannels to update the widely used three-zone model of Thome et al. (2004). The heat transfer model has a ...

Zinc blende-wurtzite polytypism in nanocrystalline ZnO films

Christophe Ballif, Cécile Hébert, Aïcha Hessler-Wyser, Duncan Thomas Lindsay Alexander, Sylvain Nicolay, Arthur Brian Aebersold, Lorenzo Fanni

ZnO is commonly observed and assumed to crystallize fully in a wurtzite structure. Indeed, While polytypism between a wurtzite and a zinc blende phase is often seen in some II-VI compounds, it has only rarely been observed in ZnO. Here, by means of automat ...

Investigation of polycrystalline ZnO film growth by quantitative TEM orientation mapping

Arthur Brian Aebersold

Polycrystalline chemical vapour deposited ZnO films are commonly used as transparent electrodes for photovoltaic devices. Over the past years much effort has been put into improving their properties. Even though these films are now well optimised for speci ...

Self-Sterilizing Sputtered Films for Applications in Hospital Facilities

César Pulgarin, Sami Rtimi, Stefanos Giannakis

This review addresses the preparation of antibacterial 2D textile and thin polymer films and 3D surfaces like catheters for applications in hospital and health care facilities. The sputtering of films applying different levels of energy led to the depositi ...

Automatic Detection of Dust and Scratches in Silver Halide Film using Polarized Dark-Field Illumination

Sabine Süsstrunk, Dominic Rüfenacht

We present a method to automatically detect dust and scratches on photographic material, in particular silver halide film, where traditional methods for detecting and removing defects fail. The film is digitized using a novel setup involving crosspolarizat ...
