Energy density of state (DOS) and molecular orbitals (MOs) of Si₁₀H₁₆ under external electric fields of (a) F_x = 0.00 au, (b) F_x = 0.01 au and (c) F_x = 0.03 au. For electric fields, 1 au = 50 V/Å. In the DOS maps, each discrete vertical blue line near the abscissa axis corresponds to a MO and the vertical black dashed lines highlight the positions of the HOMO and LUMO, respectively.
