Solid State Physics

When an electron moves through a lattice of positive ions, it experiences varying potentials. The potential of an electron at the positive ion site is zero and is maximum in between two ions. This variation in potential leads to the opening of band gaps in the energy spectrum of the electrons, resulting in the formation of energy bands in solids.

The motion of electrons in a periodic potential creates gaps in the energy spectrum at integer multiples of the periodic potential. These gaps correspond to energy bands inside the solids, leading to the discrete energy levels of electrons in the crystal lattice.

The energy spectrum of electrons in a solid exhibits gaps at integer multiples of the periodic potential due to the motion of electrons in the lattice of positive ions. These gaps in the energy spectrum give rise to the formation of energy bands in solids.

<p>In a single isolated atom, the electrons in each orbit have definite energy associated with it. In solids, the energy levels of electrons in the crystal lattice are discrete, and the motion of electrons through the periodic potential of the lattice leads to the formation of energy bands.</p> Signup and view all the answers
