What are Some Examples of Nanomaterials with Tunable Band Gaps?
Several nanomaterials exhibit tunable band gaps:
Quantum Dots: These semiconductor nanoparticles can have their band gaps precisely controlled, making them ideal for applications in displays and bioimaging. Nanowires: By varying their diameter, the band gap of nanowires can be tuned, which is useful in nanoscale electronics. Graphene: While pristine graphene has no band gap, it can be engineered to open a band gap by creating graphene nanoribbons or using chemical modifications.
