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

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 ...

Method for patterning a thin film of a solid material

Jürgen Brugger, Giovanni Boero, Xia Liu, Ana Conde Rubio, Samuel Tobias Howell

A method for patterning a thin film of (a) solid material(s), comprising the steps of providing a thin film of said solid material(s) onto a substrate, said substrate being deformable by heat and indentation; and performing a thermo-mechanical indentation ...

Localized Structures in Indented Shells: A Numerical Investigation

Pedro Miguel Nunes Pereira de Almeida Reis

We present results from a numerical investigation of the localization of deformation in thin elastomeric spherical shells loaded by differently shaped indenters. Beyond a critical indentation, the deformation of the shell ceases to be axisymmetric and shar ...

(Co-Ti-O)/Bi-Ti-O Multilayer Films with High-Frequency Electromagnetic Response

Nava Setter, Paul Muralt, Hanae Kijima

A series of (Co-Ti-O)/Bi-Ti-O multilayer films with 1-65 Co-Ti-O magnetic layers (MLs) are prepared by tandem sputtering method. The effects of the multilayers on the electromagnetic responses were investigated in the frequency range from 0.1 to 10 GHz. Th ...

Geometry-Induced Rigidity in Nonspherical Pressurized Elastic Shells

Pedro Miguel Nunes Pereira de Almeida Reis

We present results from an experimental investigation of the indentation of nonspherical pressurized elastic shells with a positive Gauss curvature. A predictive framework is proposed that rationalizes the dependence of the local rigidity of an indented sh ...

Characterization of Irradiation Damage of Ferritic ODS Alloys with Advanced Micro-Sample Methods

Johann Michler, Manuel Alexandre Pouchon, Wolfgang Hoffelner

Oxide dispersion strengthened (ODS) steels are candidate materials for advanced electric energy and heat generation plants (nuclear, fossil). Understanding the degradation of mechanical properties of these alloys as a result of service exposure is necessar ...

Probing nanomechanical properties from biomolecules to living cells

Giovanni Dietler, Sandor Kasas

Atomic force microscopy is being increasingly used to explore the physical properties of biological structures. This technique involves the application of a force to the sample and a monitoring of the ensuing deformation process. The available experimental ...

Damage evolution in coated cemented carbides under compressive contact loads

Maria-Simona Moldovan

This work deals principally with two important issues and their interrelation: the evolution of damage in coated cemented carbide tools used for cold forming, and the assessment of mechanical behavior of cemented carbides under compressive contact loads. D ...

Indentation fracture of gallium arsenide

Cédric Pouvreau

The scribe and break technique (or dicing) is a widely employed method in the industry of semiconductors to separate infrared laser diodes made from gallium arsenide (GaAs). The scribing step allows to create a precursor crack which is then propagated duri ...

Thin film delamination: A discrete dislocation analysis

William Curtin

Interface delamination during indentation of micron-scale ceramic coatings on metal substrates is modeled using discrete dislocation (DD) plasticity to elucidate the relationships between delamination, substrate plasticity, interface adhesion, elastic mism ...
