Question:
Consider a small silicon crystal measuring 100 nm on each side.
(a) Compute the total number N of silicon atoms in the crystal. (The density of silicon is 2.33 g/cm3.)
(b) If the conduction band in silicon is 13 eV wide and recalling that there are 4N states in this band, compute an approximate value for the energy spacing between adjacent conduction band states for the crystal.
