Figure 2: Narrow band gap, intermediate band gap and wide band gap perovskites have band gaps of <1.4 eV, 1.4-1.6 eV and <1.7 eV respectively (Source: Ossila Ltd.) A subset of perovskites, known as ...

LaFSe and LaFS materials have shown great potential for various optoelectronic applications, such as photovoltaics, light-emitting diodes, and photodetectors. Mixed LaFSe/LaFS compounds have been ...

The band-gap engineering through nitrogen incorporation offers a promising strategy for enhancing the photocatalytic performance of ZrO 2 -based materials. The narrowing of the band-gap in ZrO 2-x N x ...

Band gap engineering in blended organic semiconductor films based on dielectric interactions. Nature Materials, 2021; DOI: 10.1038/s41563-021-01025-z ...

It is based on engineering the band gap by substituting atoms in the material. This allows for a continuous tunability as, for example in aluminum gallium arsenide semiconductors.

The picture above shows how varying the ratio of 3T molecules (foreground) and 6T molecules (indicated in the background) in the blend allows tuning the gap continuously. 'Band gap engineering in ...
