SUMMARY
In semiconductors, drift occurs faster than diffusion due to the influence of electric fields on charge carriers. Drift is the movement of charge carriers in response to an electric field, while diffusion is the movement due to concentration gradients. The referenced document from Georgia Tech provides a detailed explanation of these processes, highlighting that drift can dominate in high electric field conditions. Understanding these mechanisms is crucial for optimizing semiconductor device performance.
