Know How, Institute

By precisely placed quantum dots, quantum light sources can be integrated onto semiconductor chips in a scalable and reproducible manner for the first time

TU Berlin paves the way for mass production of quantum chips

Optical quantum chips are considered key components of future communication and computer technologies. Their production has so far been complex because the sources needed for individual particles of light – so-called semiconductor quantum dots – formed randomly on the chip and initially had to be lo…

Satellites, like this small satellite from TU Berlin, are then dependent on batteries when they fly through Earth's shadow on their orbit and their solar cells cannot generate energy.

A focus of TU Berlin is on the battery management system, which monitors voltage, current, temperature, and state of charge of the cells, thereby ensuring safe operation in space. The development is based, among other things, on experiences from the successful TUBIN satellite mission. Here, the fully integrated TUBIN satellite can be seen in the laboratory of the Department of Aerospace Engineering.

In the "SpaceBox" project, the Department of Aerospace Engineering at TU Berlin collaborates with Berlin industry partners to develop lighter and more efficient energy storage systems for satellites.

Energy for the orbit

Satellites rely on reliable energy storage: when they pass through Earth's shadow in their orbit, their solar cells cannot generate energy. Batteries bridge these phases and support operation even when onboard, temporarily, more power is needed than the solar cells can supply. In the research projec…

A laboratory without people

It sounds a bit like science fiction: a laboratory that can plan, conduct, and evaluate its experiments largely independently. In which computers and artificial intelligence (AI) control robots work together with state-of-the-art analysis devices. And in which no human has to burn the night hours fe…

By the thickness of the bars in the grid, their spacing, and the depth of the grooves, the wavelength of the laser beams can be adjusted. Below the grid, you can see the few Bragg mirrors above the active layer (light gray), where the radiation is generated. Beneath that are many layers of Bragg mirror layers.

On the roof of the Eugene-Paul-Wigner Physics Building at TU Berlin, you can not only look into space with a telescope. Right next to it, researchers found two micrometeorites in the deposits on the ground. One of them is probably from the edge of the solar system.

Comet 67P/Churyumov-Gerasimenko, photographed on November 20, 2014, by the European Space Agency's (ESA) Rosetta spacecraft. Rosetta was only 31 kilometers away from the comet at that time. Especially when it is near the Sun, the comet repeatedly ejects fountains of gas and dust. The dust particles could then land on Earth as micrometeorites.

Micro-meteorite with a metallic bead on the edge. It formed after, during the melting phase in the Earth's atmosphere, the elements nickel and iron separated from the rest. When cooling, these metals then solidified into a separate small ball. From it, one can determine how the micro-meteorite entered the atmosphere, namely with the small ball leading.

Micro-meteorite with a turtle pattern, formed through special crystallization processes in the Earth's atmosphere. It most likely originates from the outer solar system and could have separated from comets passing by Jupiter or from rocky material in the Kuiper Belt — at a distance approximately 40 times the distance from Earth to the Sun.
