For nanoribbons of bilayer graphene, whose edge atoms are arranged in zigzag patterns, the bands of electron energies which are allowed and forbidden are significantly different to those found in monolayer graphene. This causes variations in the ways in which bilayers conduct electricity, according to research published in EPJ B.

Solar cells that use mixtures of organic molecules to absorb sunlight and convert it to electricity, that can be applied to curved surfaces such as the body of a car, could be a step closer thanks to a discovery that challenges conventional thinking about one of the key components of these devices.

Researchers synthesize a new substance that can potentially be adapted to form a semiconductor with wide applications in electronics. Semiconductors are substances that have a conductivity between that of conductors and insulators. Due to their unique properties of conducting current only in specific conditions, they can be controlled or modified to suit our needs.

Worldwide semiconductor manufacturing equipment billings reached US$13.3 billion in the second quarter of 2019, down 20 percent from the same quarter of 2018 and 3 percent from the previous quarter, SEMI, the global industry association representing the electronics manufacturing and design supply chain, reported today.
