This month’s issue focuses on thin films, and includes:
•Functional films – A deposition technique developed by the Department of Materials at Imperial College London is discussed by Neil Alford. Pulsed laser deposition and barium strontium titanate films are explored in relation to a new technique where the stoichiometry of thin films can be engineered during deposition.
•Hidden depths – Principal Research Scientist Alexander Shard of the National Physical Laboratory examines depth profiling and 3D reconstruction of organic thin films using cluster ion sputtering. The merits of secondary ion mass spectrometry as an analysis method are explored.
•The quest for new materials – The search for lead-free piezoelectrics using a high through-put combichem thin film approach. Dr Piers Anderson of Ilika Technologies discusses ultra high vacuum environments and a modified physical vapour disposition technique used to prove that this method can synthesise high quality complex oxides.
In addition, Materials World carries industry and conference news, as well as event listings. The mining features in November’s issue cover stabilisation of the Bath stone mines and reviving the Mexican lluvia de Oro mines.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
