Researchers in the US and France have succeeded in opening up the largest bandgap ever (of 0.5 eV) in graphene sheets by growing the material on the silicon face of a silicon carbide substrate. The technique could be used to engineer the electronic properties of graphene for use in applications like high-speed, high-power or high-voltage […]

Researchers at the Beijing Institute of Nanoenergy and Nanosystems at the Chinese Academy of Sciences and the Institute of Theoretical Physics at Lanzhou University are proposing new ways to increase the power output from triboelectric nanogenerators (TENGs). These devices convert ambient mechanical energy into electricity and could be used for powering wearable electronics, sensor networks […]

A new tunnel field-effect transistor (TFET) with an atomically thin current-carrying channel that operates at ultralow supply voltages has been unveiled by a team of researchers at the University of California, Santa Barbara, and Rice University in Texas. The new device, which is made from a 2D semiconducting crystal and a bulk germanium substrate, can […]

By levitating a tiny, nano-sized diamond using light, physicists in the US and Finland have created a controllable quantum system that has optical, mechanical and spin degrees of freedom. Based on a single “nitrogen vacancy” (NV) defect in the diamond, the system could be used in devices that measure extremely weak forces – or even […]

By mimicking how a natural virus works, researchers at the CNRS and the University of Strasbourg in France have made a “chemical virus” that can cross the fatty plasma membrane barrier of a biological cell. Once inside the cell, the virus can release its molecular payload – in this case a protein called caspase 3 […]
