In this video, the Fermi level is explained as the energy level at which the probability of finding an electron is 50% at absolute zero temperature. It helps determine the electrical properties of materials, especially semiconductors. This short and simple explanation covers the meaning, definition, and importance of the Fermi level in physics. #FermiLevel #SemiconductorPhysics #ScienceShorts #SciWords #ScienceEasy #PhysicsBasics #SimpleDefinition #LearnScience
