Thermoelectricity is a physical phenomenon that describes how temperature differences within a solid produce electrical voltages. An illustrative application of this would be, for example, charging a wristwatch by exploiting the temperature difference between wrist and environment. Matthias Popp ... Continue

New method finds defects in power transistors more accurately, quickly and simply Transistors are needed wherever current flows, and they are an indispensable component of virtually all electronic switches. In the field of power electronics, transistors are used to switch large currents. However, o... Continue

Publication of PhD student Maximilian Rühl appears as featured article in Applied Physics Letters Atom-size light sources, which can emit single photons, are one of the building blocks for applications in quantum technology such as quantum cryptography and quantum computers. Molecules are possible ... Continue

What to do in case of fire? Nobody wants to run into such an emergency. But if it happens, it's better to keep cool and to initiate the right steps: trigger alarm, call fire department, leave the building or try to extinguish the fire if possible. Staff members and students of the Chair of Applied P... Continue

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Ap... Continue
