How Semiconductors Work | Energy Bands, Electrons & Holes Explained | Science Series – 3C

How can a small piece of silicon control electricity and process information? Science Knowledge Series – Semiconductor Episode 3C explains the fundamental physics behind semiconductor materials, including atomic bonding, energy bands, electrons, holes and electrical conductivity. This educational episode examines: • Conductors, semiconductors and insulators • Why silicon is widely used • Silicon atoms and covalent bonding • Valence and conduction bands • The semiconductor band gap • Electrons and effective positive holes • Electron-hole pair formation • Intrinsic semiconductor behaviour • Electrical-current flow • Effects of temperature and light • Crystal defects and contamination • Why pure silicon requires controlled doping • How semiconductor materials become electronic devices The video includes supporting conceptual animation developed using NotebookLM.
