As electron hole pair (because of thermal collisions) is continuously formed in the depletion region. These are a regular flow of electrons in the direction of the N-side and of holes in the direction of the P-side. This makes a current from the N-side to the P-side. This current is called as the drift current (idr).
A solid substance has a molar volume which is smaller than that of its liquid phase. Which of the following statements regarding the solid-liquid phase transition is/are true?
Ionisation: If the amount of external energy is large enough the valence electron can gain sufficient kinetic energy (energy of movement) to be removed completely from its atom
