  Temperature-Independent Polarization of Ultrathin Phthalocyanine-Based Hybrid Organic/Inorganic Heterojunctions, Descrição: We perform the investigation on the dielectric polarization of ultrathin organic semiconducting films - c.a. 5 nm thick metal phthalocyanine ensembles (viz., CuPc, CoPc, F16CuPc) - employed to build up hybrid metal/oxide/molecule heterojunctions. Such hybrid heterostructures are fully integrated into self-rolled nanomembrane-based capacitors and further investigated by impedance spectroscopy measurements as a function of temperature (from 6 to 300 K). The dielectric polarization of the metal phthalocyanines is found to be thermally activated above a specific threshold temperature, which depends on the molecular structure. Below this threshold, the current leakage across the system is suppressed, thus evidencing intrinsic-like polarization mechanisms. The temperature-independent permittivities of the ultrathin molecular films are found to be strongly dependent on the organic/inorganic hybrid interfaces, while the calculated relaxation times are more likely related to each single-molecule polarization. Beyond the advances in determining the temperature dependence of the permittivity for ultrathin phthalocyanine films integrated within solid-state electronics, our results also support the deterministic design of novel functional devices based on nanoscale hybrid organic/inorganic heterojunctions.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (1) . , Integrantes: Ricardo Magno Lopes da Silva - Integrante / MERCES, LEANDRO - Integrante / BUFON, CARLOS CÉSAR BOF - Coordenador., Financiador(es): Conselho Nacional de Desenvolvimento Científico e Tecnológico - Auxílio financeiro / Fundação de Amparo à Pesquisa do Estado de São Paulo - Auxílio financeiro / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Bolsa.
