Charge transport in semiterm impeves thee movement of charge carriers, primarily etrones and holes, under thee influence of electric fields and concentration gradients. Understanding thee balance between drift and difusion is essential for designing and optimizing evic devices.

Fundamentals of Charge Transport

In semigraphors, charge carriers move due to two main mechanisms: drift, caused by electric fields, and diffusion, arren by concentration gradients. Drift results in a directed movement, while difusion causes carriers to spread from high to low concentration areas.
