In the search for non-lithographic methods for pattern formation on semiconductor surfaces, a facile self-assembly method relying on Au-assisted thermal annealing is employed to obtain rectangular and square micro-patterns on single crystal Ge surfaces. Such patterns can be exploited for the templated growth of biomaterials such as the valerite phase of calcium carbonate.
