Understanding insulators with conducting edges

Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled ...

Probing individual edge states with unprecedented precision

A new technique makes it possible to obtain an individual fingerprint of the current-carrying edge states occurring in novel materials such as topological insulators or 2-D materials. Physicists of the University of Basel ...

Scientists develop topological defect detection method

An international scientific team has developed a new method of probing topological structures and their topological phase transitions. The method is based on examining the reflection spectrum of electromagnetic waves reflecting ...

Engineering electron pathways in 2-D topological insulators

In a recent article published in Physical Review Letters a research collaborative has reported new insights into the electronic conduction and interference on 2-D topological insulators—an exotic kind of insulator that ...

Tunable sound transmission shapes up

The ability to control fine-scale acoustic waves known as phonons could lead to new sensing and surgery technologies, or even materials that are invisible to sonar. This pursuit led researchers at King Abdullah University ...
