This is essentially the technical and interdisciplinary application of scientific findings from basic research in physics. Technical Physics seeks not so much for knowledge as for ways of how to use the existing knowledge helpful. Especially in engineering, where the development is progressing rapidly, it is increasingly important to rapidly implement new research findings in technical progress. Lucrative modern equipment is only as long as you have a technical advantage. Important applications include microelectronics and photovoltaics. Especially in the electronics, the memory and processor manufacturing one is dependent on being able to produce the finest structures in the micro and nano scale. This will occur even quantum mechanical effects, the occurrence can be explained only by the basic research. By working together we can minimize these inevitable disruptions in the manufacturing process.

Even in biology engineering physics is used. On the one hand this is also about the smallest structures, from the processing of a cell to the genes at the molecular level. Other hand, works closely together with the chemistry, especially when it comes to nanotechnology. This is interdisciplinary from the very beginning, because there are physical structures with quantum mechanically calculable structure produced chemically in the rule. And genetic engineering has the best methods to manipulate these nanostructures. With the genes known off and it can be built even larger nanoparticles.

A large field of application is based on the materials science of solid state physics. These new materials are produced with unprecedented properties. The basic science provides and explains the relationships between molecular structure and macroscopic behavior of a substance. Technical Physics uses this knowledge, thereby creating materials with specific desired properties. This results in plastics, alloys, ceramics, high temperature superconductors, nanoparticles, coatings and special surface eg with lotus effect.

Not only research results are useful, but research methods can provide valuable services in other areas. It is also part of technical physics, the calculation methods and computer simulations extend especially to all areas of technology. Each simulation saves at least an expensive experiment, which would be in doubt even have been in vain. were replaced just as the atomic bomb tests by computer simulations, each inventor and engineer, to resort to when there is something to try. Particularly, of course, the solid-state physics are used to simulate material properties without the material ever produced have. Simulation is just as important in biophysics, to calculate the behavior of molecules. Thus gained one insight into the spatial structure of the genes that are found in electron microscopes still can not watch so closely.
