What is my favicon?

Mine is the Fermi surface of delta-doped Si(001).

It is adapted from Fig. 2 of our article http://arxiv.org/abs/1210.7113 on ArXiv (now published in PRL).

The colours have been changed from the original figure and only a small region of k_x and k_y are shown.

A higher quality image is shown below.
