The tunable electronic structure of graphene nanoribbons (GNRs) has attracted great interest due to potential applications in synthetic electronic devices 1,2,3,4. Although several top-down techniques ...

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 ...

An international research team claims to have achieved optimal passivation in inverted perovskite solar cells by applying thin layers of low-dimensional perovskite on top of a 3D perovskite film. The ...

Heterostructures of two-dimensional materials have unique properties. Among them, lateral heterostructures, which can be used to make electronic devices, are challenging to synthesize. To address this ...

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 ...

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 ...
