Abstract: According to the transnational periodically symmetry of crystal plane in its space, author introduce the Thomas-Fermi equation in crystal planar channeling electric fields; then calculate the electric fields of single crystal Si(110) and its critical angle. The good fits with the experimental data are obtained. The results show that the Thomas-Fermi equation in crystal planar channeling may describe the characters of planar channeling.
