'Bite' defects in bottom-up graphene nanoribbons
’Bite’ defects in bottom-up graphene nanoribbons
Scientists at Empa and EPFL have identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons, a novel class of carbon-based materials that may prove extremely useful in next-generation electronic devices. The researchers identified the atomic structure of these so-called "bite" defects and investigated their effect on quantum electronic transport.

New nanotransistors keep their cool at high voltages
New nanotransistors keep their cool at high voltages
Power converters play an essential role in electric vehicles and solar panels, for example, but tend to lose a lot of power in the form of heat in the electricity conversion process. Thanks to a new type of transistor developed at EPFL, these converters can perform at substantially improved efficiencies, especially in high-power applications.

Nano-mapping phase transitions in electronic materials
Nano-mapping phase transitions in electronic materials
Scientists at EPFL and the University of Geneva have combined two powerful, cutting-edge techniques to uncover the physics behind an exotic phase transition that turns a metal into an insulator. The materials they looked at are rare-earth nickelates, which are of great interest for innovating new approaches in electronics.

Kagome graphene promises exciting properties
Kagome graphene promises exciting properties
For the first time, physicists from the University of Basel have produced a graphene compound consisting of carbon atoms and a small number of nitrogen atoms in a regular grid of hexagons and triangles. This honeycomb-structured -kagome lattice- behaves as a semiconductor and may also have unusual electrical properties.

Electrically switchable qubit can tune between storage and fast calculation modes
Electrically switchable qubit can tune between storage and fast calculation modes
To perform calculations, quantum computers need qubits to act as elementary building blocks that process and store information. Now, physicists have produced a new type of qubit that can be switched from a stable idle mode to a fast calculation mode. The concept would also allow a large number of qubits to be combined into a powerful quantum computer, as researchers from the University of Basel and TU Eindhoven have reported in the journal -Nature Nanotechnology-.
