Novel electrode for flexible thin-film solar cells

26-Apr-2011

The scarcity of raw materials and increasing usage of rare metals is making electronic components and devices more and more costly. Such rare metals are used, for example, to make the transparent electrodes found in mobile phone touchscreen displays, liquid-crystal displays, organic LEDs and ...

Nanostructures stabilise lasers

Empa researchers use electron beams for chemical reactions

14-Apr-2011

Electron microscopes use focussed electron beams to make extremely small objects visible. By combining the instrument with a gas-injection system material samples can be manipulated and surface structures measuring only nanometres across can be “written”. Empa researchers, together with ...

Nanosilver: a new name – well known effects

At work against microbes for over a century

02-Feb-2011

Nanosilver is not a new discovery by nanotechnologists – it has been used in various products for over a hundred years, as is shown by a new Empa study. The antimicrobial effects of minute silver particles, which were then known as “colloidal silver”, were known from the earliest days of its ...

Empa grows 'sea urchin'-shaped structures: More efficient photocells thanks to nanostructured surfaces

02-Aug-2010

Processes which lend materials new characteristics are generally complicated and therefore often rather difficult to reproduce. So surprise turns to astonishment when scientists report on new methods which not only produce outstanding results despite the fact that they use economically priced ...

Nanoribbons for graphene transistors

Materials for tomorrow's nanoelectronics

23-Jul-2010

In the recent issue of Nature, scientists from Empa and the Max Planck Institute for Polymer Research report how they have managed for the first time to grow graphene ribbons that are just a few nanometres wide using a simple surface-based chemical method. Graphene ribbons are considered to be ...

Empa scientists synthesize graphene-like material

Polymer with honeycomb structure

25-Nov-2009

Graphene consists of a two-dimensional carbon layer in which the carbon atoms are arranged on a hexagonal lattice, resembling a honeycomb. Carbon nanotubes are rolled-up sheets of graphene, and thick piles of graphene sheets form graphite. Graphene boasts some very special characteristics - it is ...
