We describe a quantum Monte Carlo method for calculating the electronic properties of solids using wave functions with nonzero wave vectors. Our method uses the idea of" special k points" derived from band structure theory, and leads to greatly improved accuracy for insulating systems. We illustrate our method with calculations on germanium in the diamond structure.
