): The energy difference between these bands. For a material like silicon , the bandgap is approximately 1.12 eV, allowing it to act as an insulator at absolute zero but conduct current as temperature increases. Intrinsic vs. Extrinsic Semiconductors
Connecting the positive terminal to the P-side shrinks the depletion region, allowing current to flow freely.
When you put N-type and P-type silicon together, you create a —the fundamental building block of every semiconductor device.

Semiconductors are not just about computers; they are the enabling technology for nearly every major trend shaping our future.
: This is the minimum energy required for an electron to move from the valence band to the conduction band to participate in electrical flow. They sit at the heart of smartphones, medical
The most common type, crucial for CPU and memory design [3].
A semiconductor is a material with electrical conductivity between a conductor (like copper) and an insulator (like glass). Their ability to conduct electricity can be controlled and altered. This makes them the perfect foundation for electronic components. The Energy Band Theory
