Welcome back Kiryl Niherysh

Kiryl, one of our former guests, will join our group at Chalmers from the 5th of January until next September.

Kiryl is PhD student at the Institute of Physical Chemistry, University of Latvia, working in the field of micro- and nano electronics. During his stay with us at Chalmers, he will be engaged in the fabrication of quantum dots based on topological insulator (TI) Bi2Se3 nanoribbons, using electron-beam lithography and reactive ion etching.

The long-term goal of this research is to use these patterned TI nanoribbons in novel high frequency devices. In particular, the aim is to create a topologically protected single-electron charge pump that can be used as a metrological quantum current standard or, in other words, to lay the technological foundations for a TI-based device that can realize the SI Ampere.
