Fig. 3: Chemically sensitive NIXSW measurements of the C1s region of TP and TPB within the metal-organic (MO) and covalently coupled (CC) phases.

NIXSW photoelectron yields obtained using the (111) reflection of the Ag substrate for the C 1s core level, comparing MO and covalent phases of TP (red) and TPB (blue). Each profile is normalised to 1 away from the Bragg condition, with TP results offset by 1 unit for clarity. The obtained Cf and Cp values are shown for each fit.
