Topological quantum phase transitions driven by external electric fields in Sb(2)Te(3) thin films
Using first-principles calculations, we show that topological quantum phase transitions are driven by external electric fields in thin films of Sb(2)Te(3). The film, as the applied electric field normal to its surface increases, is transformed from a normal insulator to a topological insulator or vi...
