The Fascinating Dance of Electrons and Holes: Exploring Charge Carrier Transport and Recombination The world around us thrives on the flow of energy. From the light illuminating your screen to the electricity powering your home, it's all about the movement of tiny particles called charge carriers. In the realm of technology, understanding how these carriers – electrons and holes – transport themselves and interact is crucial for developing efficient and powerful devices. Charge carrier transport refers to the movement of electrons and holes within a material under an applied electric field. Imagine a crowded hallway: when people (charge carriers) are pushed by a force (electric field), they start moving in a particular direction. This movement can be influenced by various...
