What Factors Influence Charge Carrier Recombination?
Several factors influence charge carrier recombination in catalytic systems:
1. Material Properties: The intrinsic properties of the semiconductor material, such as bandgap, defect density, and crystallinity, play a crucial role. 2. Surface Properties: The presence of surface states, which can act as recombination centers, affects the rate of recombination. 3. Particle Size and Morphology: Smaller particles with higher surface area to volume ratios can enhance charge separation but may also introduce more recombination centers. 4. Doping and Composite Formation: Introducing dopants or creating heterojunctions can help in separating charge carriers and reducing recombination.
