The electron microscope, like many other complex technological developments based upon current scientific research, cannot be associated exclusively with a single inventor. In the early 1930s several laboratories were at work on a super-microscope that would use electron waves, instead of light waves, to magnify a microscopic specimen. However, it is generally agreed that the German engineer Ernst Ruska designed and built the first working electron microscopes (1931-1933). Ruska's contribution to the science of physics, and to its applications in the fields of biology and medicine, was recognized in 1986 when he was awarded the Nobel Prize along with two other pioneers of modern microscopy, Gerd Binnig and Heinrich Rohrer.

    Extractions: Ruska, Ernst August Friedrich Nìmecký fyzik, elektroinženýr a držitel Nobelovy ceny za fyziku pro rok 1986 za návrh prvního elektronového mikroskopu a dalších vylepšení tohoto zaøízení. O cenu se dìlí spolu s Gerdem Karlem Binnigem z Nìmecka a Heinrichem Rohrerem ze Švýcarska, kteøí cenu obdrželi za návrh vzorkovacího tunelového mikroskopu. Narodil se v Heidelbergu. V roce 1931 dostal titul elektroinženýr na universitì v Berlínì a o dva roky pozdìji také titul Ph.D. V roce 1937 pøijal místo v laboratoøích Siemens-Reiniger-Werke. Zùstal zde až do roku 1955, kdy se stal øeditelem Institutu pro elektronovou mikroskopii, který byl zøízen pøi Fritz Haberovì institutu. V téže dobì uèil jako profesor na Berlínské technice a to od roku 1957 až do roku 1972, kdy odešel do dùchodu. Pøed tím, než opustil ve tøicátých letech universitu v Berlinì, již pøispìl k vìdeckému poznání. Vìdìl, že elektrony mají vlnový charakter a vìøil, že je pùjde využít k podobným úèelùm jako svìtlo. Ruska doufal, že magnetické pole mùže ovlivnit svazek elektronù, pøípadnì ho zaostøit. Poté, co si všechny pøedpoklady ovìøil experimentálnì, zaèal vytváøet elektronový mikroskop. Ruska si uvìdomil, že zvìtšení elektronového mikroskopu bude mnohem vìtší než u jeho optického protìjšku, protože vlnové délky elektronù jsou mnohem kratší než vlnové délky viditelného svìtla. V 1932 Ruska a spolupracovníci, nìmecký fyzik Max Knoll (pod jehož vedením dostal doktorát) postavili první primitivní elektronový mikroskop. Pøestože to byl jen první pokus a mikroskop nebyl pøímo použitelný dokázal pozorované pøedmìty zvìtšit 400×.

As a student, Ernst Ruska experimented with the theory that electron currents, which have a shorter wavelength than light, could magnify images beyond the capabilities of the light microscope. On April 7, 1931 (at the ripe old age of 24), Ruska conducted the experiments that would earn him a Nobel Prize. He obtained experimental proof that, similar to using multiple lenses to magnify specimens in light optics, an object's image could be further magnified by using two short electromagnetic coils. The resolving power of a light microscope is limited by the wavelength at which light travels (about 4,000 angstroms). The electron microscope uses an electron beam with a wavelength of less than 1 angstrom, which can magnify objects up to 1 million times. Some of the electrons pass through the specimen, and others bounce off it. The scattered electrons, focused by a pair of electromagnets that form the "lens" of the microscope, produce a visible image on a fluorescent screen or photographic film.

The ER-C operates on national programmes on the physical fundamentals of nanoelectronics and condensed matter. Within this framework, the main fields of activity comprehend the development of state-of-the-art high-resolution microscopy techniques for the quantitative analysis of nanoscale materials at the verge of present instrumental resolution capabilites together with the application of these techniques to the analysis of a multitude of solid state materials. For these purposes, specifically developed quantitative techniques of high-resolution, analytical, in-situ and conventional transmission electron microscopy are applied to the investigation of lattice defects and for the atomic scale characterisation of heterointerfaces. Materials currently on focus cover oxide ceramics and superconductors metals and semiconductors as well as heterostructure combinations synthesised upon these materials.
