Thickness dependent TrAMP dynamics.
(a) TrAMP kinetic at λprobe = 900 nm for 5 nm/5 nm bilayer of P3HT/PCBM.A multiexponential fit (A(t)) is also shown. (b) Similar kinetic and the fit (B(t)) for a 5 nm film of P3HT. TrAMP kinetics for the bilayers with 10 nm (c), 20 nm (d) and 50 nm (e) thicknesses of P3HT with a constant 5 nm layer of PCBM on the top. Also shown are the fits obtained by a linear superposition of A(t) and B(t) in each of the three cases.
