What are the most common semiconductor materials?
Silicon and germanium are the most widely used elemental semiconductors, while compounds like gallium arsenide are crucial for specific applications like LEDs and lasers.
Can semiconductors conduct electricity without any doping?
Yes, intrinsic semiconductors can conduct electricity but much less efficiently than extrinsic semiconductors, which are enhanced by doping.
What are the differences between n-type and p-type semiconductors?
N-type semiconductors have extra electrons as charge carriers, making them negatively charged. P-type semiconductors have holes as charge carriers, giving them a positive charge.
How does temperature affect semiconductor behavior?
As temperature increases, more electrons gain enough energy to jump from the valence band to the conduction band, decreasing the material's overall resistance.
What makes a material a semiconductor?
A semiconductor is defined by its band gap which is small enough to allow the excitation of electrons from the valence band to the conduction band under normal conditions.
