Dresden Center for Nanoanalysis (DCN)

Due to their ongoing miniaturization, the performance of modern devices may be affected already by few individual atoms. Together with the establishment of new fabrication routes and the incorporation of novel materials, this renders high resolution chemical and structural analyses indispensable in order to gain a better understanding of the device structures and to finally improve them. Since in addition to the mere choice of materials also the synthesis process effects the resulting function, both in-situ and in-operando characterizations become increasingly important.

To cope with this enhanced analytical demand, the recently founded Dresden Center for Nanoanalysis (DCN) serves as a central user facility to the TU Dresden and its neighboring scientific institutions. The DCN aims at gaining synergies by centralizing the access to expensive high-end scientific tools in particular in the fields of microscopy with electrons, ions and X-rays. It offers a modern infrastructure with highly specialized ultra-low noise laboratories (click here for a movie on the construction of our TEM rooms), state-of-the-art equipment as well as the necessary know-how. The DCN conducts nanoanalytical service measurements, provides for user training and strives towards own methodological developments.

 

 

The DCN is organized in a three-fold core-shell structure. While the DCN Core Facility run by the DCN Core Team provides for the lab infrastructure, central equipment (incl. maintenance), know-how, user training and device access, it is surrounded in the same building by additional groups from the TU Dresden. These groups share their own equipment with regular DCN users and/or try to interface currently solely internally available techniques to a wider user group – thereby successively expanding DCN’s methodical portfolio within the DCN Lab Extension. The scientific environment of the TU Dresden – in particular the DRESDEN-concept institutes – provide access to additional equipment for (non-local) use outside the campus of TU Dresden, thereby contributing to the DCN Virtual Lab, DCN’s outermost organizational shell.

Being a technology platform of cfaed, the tools and methods available in the DCN can be accessed by all users within TUD and the DRESDEN-concept community, and at a later stage they will be offered nationwide and internationally.

DCN’s magnetically shielded transmission electron microscopy lab.

Great joy...

at the Dresden Center for Nanoanalysis (DCN): In a competition run by Protochips, Inc. (U.S.), the analytics user facility of the TU Dresden had submitted an application - and was successful! Besides the international recognition and reputation that go along with the prize, the DCN will be awarded a state-of-the-art and world-wide unrivalled Axon synchronization tool. The Axon system will perfectly complement and further enhance the center's capabilities of in-situ electron microscopy, a field in which the DCN is already now excellently positioned. The hardware and software components will soon be installed on the DCN’s high-resolution transmission electron microscope JEOL Jem-F200.

While electron microscopy usually demands ultimate stability of the sample under investigation, this novel synchronization tool will allow us to observe even dynamic and kinetic processes such as structural or chemical changes in a material, e.g., during heating or in gas atmospheres with up to atomic resolution.
