The binding energy of an electron in a crystal lattice

Reference no: EM13552216

The binding energy of an electron in a crystal lattice is 1.2 x10^(-4) eV. Use the uncertainty relation to estimate the size of the spread of the electron wave function. How many lattice sites will that include, assuming that the spread is spherically symmetric and that the spacing between the ions is 0.12 nm?
