Which of the following statements is FALSE regarding the ‘Drift’ of charge carriers?

It is the dominant carrier transport mechanism when an electric field is applied in the semiconductor. Holes move in the direction opposite to that of the applied field. During drift, the carrier transport is characterized by their respective electron/hole mobilities. During drift, electrons and holes move in opposite directions

Holes move in the direction opposite to that of the applied field.

Positive charges move in the direction of the E field, by definition.

Holes move in the direction opposite to that of the applied field.

To determine which statement is false regarding the 'drift' of charge carriers, let's break down each statement and analyze it:

1. "It is the dominant carrier transport mechanism when an electric field is applied in the semiconductor."
This statement is true. Drift is the primary mechanism of carrier transport when an electric field is applied in a semiconductor.

2. "Holes move in the direction opposite to that of the applied field."
This statement is true. In a semiconductor, holes, which are the absence of electrons, move in the opposite direction to the applied electric field during drift. They move towards the positive terminal of the electric field.

3. "During drift, the carrier transport is characterized by their respective electron/hole mobilities."
This statement is true. The drift of charge carriers in a semiconductor is characterized by their respective mobilities. Electron mobility represents the speed at which electrons move in response to an electric field, while hole mobility represents the speed at which holes move.

4. "During drift, electrons and holes move in opposite directions."
This statement is true. During drift, both electrons and holes do move in opposite directions. Electrons move in the direction of the applied electric field, towards the negative terminal, while holes move in the opposite direction, towards the positive terminal.

Based on our analysis, all of the statements are true regarding the 'drift' of charge carriers. Therefore, none of the statements are false.

During drift, electrons and holes move in opposite directions
