The derivation is similar to that done for the 3D case in Example 2.5, and for the 2D case shown
in class. For the 1D case we have
The energy-momentum relation is still given by , just as it was for the 3D and2D cases.

Following the procedure outlined in Example 1.4, page 11:
1. Plane intersects axes at a, 2a and 3a.
2. Divide the intercepts by a and invert: 1, , .
3. Multiply by 6 to obtain the set of smallest whole numbers: 6, 3, 2

2.30 The probability that an energy state in the conduction band is occupied by an electron is
given as
Because the energy state is in the conduction band its value must be . Therefore is, at most,
0.179eV below . This puts
