Drift Current and Diffusion Current in Semiconductor: The two basic processes which cause electrons and holes to move in a semiconductor are : drift, which is the movement. The term **drift** **current** is used because electrons, being very low mass, move at pretty high velocity due to thermal energy. During **drift** **current** there is a net movement in addition to the random movements. **Drift** **current** is ohmic **current**, proportional to the voltage change with distance. **Diffusion** **current** takes place with no electric field..

Solution. **DRIFT CURRENT** :- **Drift current** is the electric **current**, or movement of charge carriers, which is due to the applied electric field, often stated as the electromotive force over a given distance. **DIFFUSION CURRENT**. An important difficulty arises in the formal description of the classical Hall effect. This is due to the fact that the amount of electric charges accumulated at the edges of a Hall bar is not directly imposed by the external constraints but by the system itself, in reaction to the **current** injection and the effective magnetic field (like for the Le Chatelier-Lenz principle). As a consequence.

The **diffusion** **current** in a p-n junction is A from the n-side to the p-side B from the p-side to the n-side C from the n-side to the p-side if the junction is forward-biased and in the opposite direction if it is reverse-biased D from the p-side to the n-side if the junction is forward-biased and in the opposite direction if it is reverse-biased. 8.7 **Drift and diffusion current**s. Often, we come across **drift and diffusion current**s in semiconductors. The **drift current** occurs due to an applied electric field on a semiconductor. Earlier we said that **drift** **current** **and** **diffusion** **current** are present even though J = 0 in equilibrium. This is because for every electron that diffuses from the n -side to the p -side there is an electron that **drifts** from the p -side to the n -side. The same goes for holes. The two **currents** balance each other and the total **current** density J = 0.
