Il band-gap engineering è l'insieme delle tecniche e dei processi che permettono di controllare e ingegnerizzare in maniera precisa le giunzioni (zone interfacciali che si presentano quando si pongono a contatto materiali con un diverso reticolo cristallino) e le bande proibite di materiali, tipicamente semiconduttori.
Band-gap engineering is the process of controlling or altering the band gap of a material. This is typically done to semiconductors by controlling the composition of alloys, constructing layered materials with alternating compositions, or by inducing strain either epitaxially or topologically.

Band-gap engineering is the process of controlling or altering the band gap of a material by controlling the composition of certain semiconductor alloys, such as GaAlAs, InGaAs, and InAlAs. It is also possible to construct layered materials with alternating compositions by techniques like molecular-beam epitaxy .
31 ott 2017 · In this Review, we focused on the important emerging theme of bandgap engineering through alloying with control over a wide range of compositions that is enabled by nanoscale materials and ...
