What we have learnt
- Bipolar junction transistors function through the interaction of electrons and holes at their junctions.
- The behavior of minority carriers is critically affected by the junction biasing.
- Mathematical expressions can accurately describe the current flow in BJTs under various conditions.
Key Concepts
-
Term: Bipolar Junction Transistor (BJT)
Definition: A type of transistor that uses both electron and hole charge carriers for its operation.
-
Term: Minority Carrier Profile
Definition: The distribution of minority charge carriers (electrons in p-type material or holes in n-type material) influencing current flow.
-
Term: Diffusion Current
Definition: The current caused by the movement of charge carriers from a region of high concentration to one of low concentration.
-
Term: Reverse Bias Voltage
Definition: A condition in which the voltage applied to a p-n junction prevents current from flowing, except for a small leakage current.
