Intensities of p(TM) electromagnetic modes for wave vectors: a \(Q=0.001\,{{a}_{0}}^{-1},\) b \(Q=0.01\,{{a}_{0}}^{-1},\) c \(Q=0.05\,{{a}_{0}}^{-1}\) calculated in the atomistic (dotted line) and 2D model (full line). Colours (blue, yellow, magenta and green) correspond to increasing levels of surface charge doping (n = 0 e cm−2, 1 × 1013 e cm−2, 5 × 1013 e cm−2, and 1 × 1014 e cm−2) which increases the intensity and separation of DP and AP electromagnetic modes. Intensities were normalised to unity w.r.t. the π → π* peak.
