Bandgap Engineering

Bandgap engineering is the process of manipulating the energy difference (bandgap) between the electrons in a material, which defines its electronic and optical properties. By altering the bandgap, scientists can create materials that are tailored for specific applications, such as better solar cells, efficient LEDs, or advanced semiconductors. This can be done through methods like changing the material's composition, layering different materials together, or applying external pressure. Essentially, bandgap engineering allows us to design materials that can efficiently absorb or emit light and conduct electricity, enabling technological advancements in various fields.
