  1. \(\Delta E\) (\({E}_{{{{{{\rm{F}}}}}}}=0\)) denotes the energy separation (in the unit of meV) between the exciton and exciton polaron at the charge neutrality point. \({{{{{\rm{d}}}}}}(\Delta E)/{{{{{\rm{d}}}}}}{E}_{{{{{{\rm{F}}}}}}}\) denotes the slope of \(\Delta E\) with respect to the Fermi energy (\({E}_{{{{{{\rm{F}}}}}}}\)).
