New materials for extra thin computer chips

Ever smaller and ever more compact—this is the direction in which computer chips are developing, driven by industry. This is why so-called 2-D materials are considered to be the great hope: they are as thin as a material ...

Topological insulators feature lossless conduction at the edges

Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining ...

4-D electric circuit network with topology

In recent years, topology has emerged as an important tool to classify and characterize properties of materials. It has been found that many materials exhibit a number of unusual topological properties, which are unaffected ...

The coolest LEGO in the universe

For the first time, LEGO has been cooled to the lowest temperature possible in an experiment which reveals a new use for the popular toy.
