👉 Charge engineering is a sophisticated technique used in the design and optimization of electronic devices, particularly in semiconductor materials and structures. It involves manipulating the distribution and mobility of charge carriers—electrons and holes—within a material to enhance its electrical properties. This is typically achieved by introducing dopants, creating heterostructures, or applying external electric fields to control the energy levels and band alignment. The goal is to optimize parameters such as carrier concentration, mobility, and recombination rates, thereby improving device performance in applications like transistors, solar cells, and LEDs. By carefully engineering the charge distribution, researchers can achieve higher efficiency, faster switching speeds, and better overall functionality in electronic and optoelectronic devices.
