Due to the exceptional properties derived from its non-trivial band topology protected by time-reversal symmetry, topological insulator has become the focus of the current research. Based on first principle calculations, we calculated the energy band of topological insulator with van der Waals force being taken into account. Moreover, we discussed how to develop students' creativity in doing researches in the teaching process.
