Module 2 – Sample 2 – Basics Of Electronics Engineering Notes – KTU Notes
Basic Electronics Semiconductor —I Materials that permit flow of electrons are called conductors (e.g., gold, silver, copper, etc.). Materials that block flow of electrons are called insulators (e.g., rubber, glass, Teflon, mica, etc.). Materials whose conductivity falls between those of conductors and insulators are called semiconductors. Semiconductors are “part-time” conductors whose conductivity can be controlled. … Read more
