Heterojunctions are interfaces formed between two dissimilar semiconductor materials with different band gaps, electron affinities, or work functions. These nanoscale junctions play a crucial role in ...

Junctions between the two different materials, single-wall carbon nanotubes (SWCNTs) and perovskite (CsPbBr 3) quantum dots (QDs); a mechanically stable and easily customized photovoltaic material ...

A team of physicists and chemists has developed a highly sensitive sensor, which was made possible by a new heterostructure consisting of atomically precise graphene nanoribbons. An international ...

2D-materials have special lattice structures. Atoms in the same layer were usually bound by the covalent bond, while the force between layers is van der Waals coupling. They have super clean surfaces ...

Chinese and U.S. researchers have teamed up to synthesize and study the first organic single-crystal nanoribbon to feature a p-n heterojunction (J. Am. Chem. Soc., DOI: 10.1021/ja102779x). Most ...
