The study of electrical and dielectric properties of devices functionalized with nanostructures is essential to comprehend their operational characteristics and to design applications. In this sense, this project aims the development and characterization of hybrid nanostructures consisting on self-assembled monolayers, surface metal-organic frameworks (SURMOFs) and metallophthalocyanines ultrathin films. These structures will be deposited on metal electrodes coated with films of dielectric oxides. Here, parallel-plate capacitive platforms and ultracompact heterojunctions will be used, applying them to analyze the nanostructures in both solid/solid architecture and in solid/liquid interface. The nanostructure platforms will be characterized by electrical AC and DC measurements, exploring the electrical properties of the nanostructures at both solid/solid and solid/liquid configurations. In particular, the electrical properties of SURMOFs have been barely evaluated. Therefore, this study will allow us to explore the properties of SURMOFs and apply them in devices based on electrical transduction. Here, we aim mainly applications containing systems that operates in liquid medium, e.g., sensors and biosensors.
