With first-principles theoretical analysis, we show that the observed electon-hole asymmetry arises from the radically different constitution of its conduction and valence bands involving $\\pi$ and $\\sigma$ bonding states respectively, whose symmetry permits coupling with only the phonons that pres","authors_text":"A.
