10 Questions
Solid materials can be classified into three categories based on their electronic structure and properties: Conductors, Semiconductors and ______
Insulators
Valence band contains energy levels of valence electrons which remain in the outermost ______
orbit
Conduction band contains energy levels of free electrons (conduction electrons) Band gap is the gap between the top of the valence band and the bottom of the conduction band which does not contain any energy ______
levels
E K Diagram Gives energy-momentum relationship for an ______
electron
Gives an idea of band ______
gap
What are the three categories in which solid materials can be classified based on their electronic structure and properties?
Conductors, Semiconductors, and Insulators
What is the valence band? What kind of energy levels does it contain?
The valence band contains energy levels of valence electrons which remain in the outermost orbit.
What is the conduction band? What kind of energy levels does it contain?
The conduction band contains energy levels of free electrons (conduction electrons).
What is the band gap? What does it signify?
The band gap is the gap between the top of the valence band and the bottom of the conduction band which does not contain any energy levels. It signifies the energy required for an electron to move from the valence band to the conduction band.
What does the E K diagram provide an idea of?
The E K diagram provides an energy-momentum relationship for an electron and gives an idea of the band structure and band gap.
