  "abstract": "Vertical charge injection and out-of-plane heat transport are central to organic electronic materials, yet remain largely unexplored in solution-processed thin films of donor-acceptor charge-transfer systems. Here, we investigate Ph-BTBT-C10, F4TCNQ, and their 1:1 charge-transfer complex (CTC) by combining structural and morphological characterization with conductive atomic force microscopy and scanning thermal microscopy. The measurements show that while Ph-BTBT-C10 and F4TCNQ present highly non-symmetric injection and low currents, the CTC exhibits increased out-of-plane conduction and a reproducible polarity-dependent metal-semiconductor-metal response, consistent with a distinct interfacial energetics landscape and enhanced effective screening/injection behavior induced by charge transfer. The out-of-plane thermal conductivity of the CTC is 1.47 ± 0.24 W m-1 K-1 and that of Ph-BTBT-C10 is 0.25 ± 0.16 W m-1 K-1. Remarkably, F4TCNQ displays an unusually high out-of-plane thermal conductivity of 2.51 ± 0.83 W m-1 K-1, which, if confirmed by independent techniques or theoretical approaches, would establish it as an important benchmark for vertical heat transport in organic molecular films. Thus, CTC films provide an increased out-of-plane conductivity, while limiting the increasing in the thermal conductivity, thereby highlighting donor‑complex engineering as a promising strategy for designing high‑performance thermoelectric materials.",
