Band gap renormalization and work function tuning in
WebMoS₂ is Molybdenite structured and crystallizes in the hexagonal P6₃/mmc space group. The structure is two-dimensional and consists of two MoS₂ sheets oriented in the (0, 0, 1) direction. Mo⁴⁺ is bonded to six equivalent S²⁻ atoms to form distorted edge-sharing MoS₆ pentagonal pyramids. All Mo–S bond lengths are 2.42 Å. S²⁻ is bonded in a 3-coordinate … WebNov 6, 2003 · Polymer diodes require cathodes that do not corrode the polymer but do have low work function to minimize the electron injection barrier. First-principles calculations demonstrate that the work function of the (1000) surface of the compound Ca2N is half an eV lower than that of the elemental metal Ca (2.35 vs 2.87eV). Moreover, its reactivity is … cheatpops.db
