WebDec 12, 2024 · The layer-dependent degradation was successfully interpreted by considering the oxidation model based on the Marcus–Gerischer theory (MGT). In the dark, the electron transfer rate from BP to oxygen molecules depends on the number of layers as these systems have different carrier concentrations. This work not only provides a deeper ... WebExtending the Marcus–Gerischer theory to PCET by including the excited electron–proton vibronic states and the proton donor–acceptor motion provided an apparent reorganization energy of 1.01 eV. This study demonstrates that the Marcus–Gerischer theory initially developed for ET can be reliably extended to PCET for quantifying and ...
