In what direction do electrons flow in a semiconductor diode?

In a semiconductor diode, electrons flow from the anode to the cathode. This is because the anode is connected to a higher potential (positive voltage), while the cathode is connected to a lower potential (negative voltage). When a forward bias is applied to the diode, it allows current to flow through, which consists of the movement of electrons from the anode (where they are more abundant) toward the cathode.

In this context, it's important to remember that the conventional current direction is opposite to the electron flow. While current is said to flow from the positive terminal (anode) to the negative terminal (cathode), the actual movement of electrons, which carry the charge, flows from the anode to the cathode. This understanding of electron flow is fundamental in grasping the behavior and characteristics of semiconductor diodes in circuit applications.
