Abstract:
EU-funded scientists in Poland have completed tests on the TITAN CUBED 80-300, a high-resolution transmission electron microscope.

Polish scientists present super electron microscope

EU | Posted on December 13th, 2010

This advanced tool makes it possible for researchers to perform fast and accurate characterisations of semi-conductor structures used in laser and diode productions, and closer testing of materials used in spintronics and nanotechnology.

Partial funding for the project came from the EU's Innovative Economy 'Operational Programme', under the European Regional Development Fund (ERDF). The Innovative Economy scheme supports research and development (R&D) and information and communication technologies (ICT) projects.

The researchers from the Institute of Physics of the Polish Academy of Sciences (PAS) tested and installed the microscope over a four-month period. It is one of the leading facilities found in Europe, according to them.

'Electron microscopy has been the subject of our interest for more than 35 years,' says Professor Leszek Sirko, scientific director of the Institute of Physics. 'TITAN guarantees to carry on our investigation on the highest world level.'

The team says high-resolution transmission electron microscopy (HRTEM) is a valuable tool for researchers wishing to study nanoscale properties of crystalline materials including metals and semi-conductors.

Individual atoms and structural defects can be imaged at these small scales. 'So small objects we are not able to see by use of visible light,' explains Kamil Sobczak, a PhD student at the Institute's Electron Microscopy Group. The team used a beam of electrons instead of a beam of light to 'illuminate' the object.

The microscope consists of a vertical column, on which the electron gun is placed. Once the electron beam has passed through the object, it comes through a system of lenses to create the super magnified image of the object.

According to the team, the object must be very thin (up to one micron, maximum). The group has also picked up a device that enables highly efficient sample thinning, namely a Focus Ion Beam (FIB). 'At present, sample preparation takes us about one week (with standard techniques),' notes Alicja Szczepanska from the Electron Microscopy Group. 'By using an FIB, a sample will be ready after a few hours.'

An electron energy loss spectrometer is included in the state-of-the-art microscope, allowing for holographic imaging and liquid nitrogen temperature testing. The scientists point out that the facility contains high-quality electronic optics, as well as highly stable accelerating voltage and super sensitive image detectors.

The microscope's distinct qualities allow researchers to follow specific processes such as changes in temperature. Researchers will benefit immensely from the microscope, they add.

Based on the results of the microscopic tests 'we will be able to inform technologists, which colour of light can be emitted by a selected part of the investigated device', says Professor Piotr Dluzewski, head of the Electron Microscopy Group.

Regular work of the microscope will get off the ground in January 2011. Scientists and business actors, both in Poland and abroad, are expected to use the new microscope.
