Larger the bandgap the more insulating the material true or false
Answers
Is the given statement is true that larger the bandgap more the insulating material. When capacitor space which lies between the conduction band and valence band. It helps in transmission of electrons from the conduction band to the valence band.
The electrons are transmitted in the form of waves if through the band gap. It goes according to the de Broglie hypothesis. Electrons is a particle cannot cover the bandgap or else the propagation vector would become complex. Hence the electron as a wave passes through the band gap.
The statement “Larger the band gap the more insulating the material” is absolutely true.
This is because band gap refers to the energy required for an electron to jump from the valence band to the conduction band.
More the energy required, the more difficult it becomes for the electron and thus, the material to become conducting which is why it becomes more insulating.
