👉 Carrier engineering is a sophisticated process in the field of materials science and nanotechnology that involves modifying the electronic properties of semiconductor materials by introducing or altering specific atoms within their crystal lattice. This technique allows scientists to tailor the bandgap, conductivity, and other electronic characteristics of materials to suit specific applications, such as improving the efficiency of solar cells, enhancing the performance of transistors in electronic devices, or optimizing materials for energy storage. By precisely controlling the type, concentration, and spatial distribution of dopants or defects, researchers can create materials with desired functionalities, bridging the gap between fundamental material science and practical technological applications.
