Project On Semiconductor Class 12 [ HD • FHD ]

Added with trivalent impurities (e.g., Boron), creating "holes" (positive charge carriers).

Signature of Principal

The diode offers very high resistance, and almost no current flows. project on semiconductor class 12

In conclusion, my project on semiconductors was an eye-opening experience that helped me understand the importance of these materials in modern electronics. I hope that my findings will inspire others to explore the fascinating world of semiconductors and their applications.

To understand semiconductors, we must look at the energy bands of atoms in a solid. Added with trivalent impurities (e

Signature of External Examiner

The conductivity of intrinsic semiconductors is low. To increase conductivity, we add impurities in a process called . The doped semiconductor is called an Extrinsic Semiconductor. Added with trivalent impurities (e.g.

There are two main types of semiconductors:
