First publications TOPSQUAD

The first TOPSQUAD results have been published in prestigious journals.

A first paper that constitutes the project’s foundation has been published in January 2020 in Nano Letters and gives evidence for the presence of a hard superconductive gap in a Ge-Si nanowire device. This represents an important step towards creating and detecting the Majorana bound states in this system.

 

A second paper published in February 2020 in Advanced Materials, reports on the growth on site-controlled of Ge hut wires as a prerequisite toward scalable qubit devices using nanowires on silicon.
