Active Thin Films: Thin film batteries, anode and cathode materials
Vacuum Technology and Coating
Structure and operation of batteries, thin film batteries (TFB), and thin film Li-ion batteries (TFLIB) in particular, were introduced last month. Basic battery structure, shown in Figure 1, consists of substrate, electrolyte, current collector, anode, cathode, and separator. Compared to their larger cousins, TFB are all solid state, and are assembled layer by layer by physical vapor deposition (PVD), chemical vapor deposition (CVD), self assembly, sol gel processes, pulsed laser deposition (PLD) and atomic layer deposition (ALD).

MIT researchers use graphene to create transparent, flexible solar cells
AZO Nano
MIT has come up with a new flexible, transparent solar cell which would make it possible for solar cells to be used in numerous items around us in the near future – in cell phones and laptops, on windows and walls, and more.

Diamond joins the realm of 2-D thin films, study suggests
ScienceNews
Diamonds are going 2-D. The superhard form of carbon can be forged in thin films known as diamondene, new evidence suggests. While graphite, the form of carbon found in pencils, can be made into atom-thick sheets known as graphene, scientists have struggled to create two-dimensional films of its relative, diamond.

Vacuum observations & perspectives
Vacuum Technology & Coating Weblog
Vacuum use is only likely to increase going forward, especially when producing very small and complex components like ICs and MEMS for sophisticated products. Doing so in a vacuum is the only practical way to prevent gaseous and particulate contamination. Vacuum is absolutely essential for semiconductor production.

The microscope that digs deep for answers
CERN
XB540 – it may look like the code name of a secret agent, but in fact it is a scientific tool used for nanoscale investigations at CERN. The thin film experts from the Vacuum, Surfaces and Coatings group have been among the first to put the results to use.

'Near-pefect' solar absorber highlights bright outlook for UAE's sun-powered future
The National
One thing the UAE definitely does not lack is sunshine. During even the least sunny month, January, there is an average of 8.1 hours of sunshine per day in Dubai, while the blazing heat of June sees an extraordinary 11.5 hours per day. As a result, the country is one of the best places in the world for solar power plants, and authorities have capitalised on this by making huge investments.

TECHNICAL TIPS


Gold And Aluminum Evaporation Tips
Be sure to read ahead for tips on gold and aluminum evaporation. Gold can be successfully evaporated by a variety of methods. Boats, Baskets, crucibles, and filaments are the most common types of sources used. However, gold, when molten, has 2 issues. Aluminum is a very popular material for evaporation. We have many different sources that can be used to successfully evaporate aluminum. However, there are a few common problems that occur when evaporating this material.
