Накратко на български

Хибридни системи от златни наночастици и прозрачни проводящи оксиди се изследват за управление на светлината чрез електрическо напрежение. Това помага за разработването на активни оптоелектронни устройства с контролирани оптични свойства.

PLasmonics@Transparent cONductive oxidEs

The capability of chemically and physically engineering the electrical and optical response of solids represents both the driving force and the consequence of the tremendous technological development of electronics, optoelectronics and plasmonics within the past century. PLaTONE proposed the realization of a novel class of materials combining plasmonic resonators with TCO-based thin-film capacitors. The aim of this project was the fabrication and the electrical/optical characterization of these systems and the exploitation of the mutual interaction between the plasmonic nanostructures (NSs) and the voltage-controlled dielectric properties of the TCO for achieving an active optoelectronic device. In particular, we proposed the realization of Nanostructure-Transparent Conductive Oxide (NS-TCO) hybrid systems featuring the electrical control of their electrical and optical properties via field effect. This kind of systems would be introduced as electrodes in a capacitor configuration which would consist of a stack of plasmonic NSs, an active TCO layer, a high-permittivity insulator and a conductive-oxide substrate. Al-doped ZnO (AZO) films, separated from the conductive-oxide substrate—backgate of the system—by the insulating layer, would act as the active TCO material. The AZO-based multilayer would work as substrate for plasmonic NS deposition: its high surface energy should ease the NS formation by solid-state dewetting. The goal was the tuning of the localized surface plasmon resonance (LSPR) wavelength of the noble-metal NSs and in particular gold (Au) nanoparticles (NPs) on AZO via field-effect. The researcher within the project performed: Fabrication and optical, electronic and electrical characterization on each layer of the proposed capacitor Fabrication of the capacitor and Spectroscopic Ellipsometry on the capacitors upon bias Simulations of the expected optical response of the capacitors upon bias. Study of the optical properties of TCO thin films and NS-TCO thin films Investigation of hot-electron injection process in the NS-TCO systems by performing pump-probe experiments

Цел на проекта

The capability of chemically and physically engineering the electrical and optical response of solids represents both the driving force and the consequence of the tremendous technological development of electronics, optoelectronics and plasmonics within the past century. As a most relevant example, the process—known as doping—of introducing foreign impurities in suitable hosts has led, among others, to the development of Transparent Conductive Oxides (TCOs), materials combining visible-light optical transparency with high electrical conductivity that are nowadays an irreplaceable component of solar cells and touch screens. Plasmonics and photonics, in parallel, have reached unprecedented levels of control of electromagnetic energy thanks to the possibility of fabricating and tailoring metallic nanostructures with physical dimensions down to the micro- and nano-scale for nano-antennas, perfect absorber and cloaking applications, to mention a few. One of the new challenges that researchers and engineers are facing is merging optical and electrical control in a single device for developing next-generation photovoltaic, opto-electronic devices and energy-efficient solid-state lighting.PLaTONE proposes the realization of a novel class of materials combining plasmonic resonators with TCO-based thin-film capacitors, a system envisaged in literature but not yet achieved. PLaTONE will address the fabrication and the electrical/optical characterization of these systems and exploit the mutual interaction between the plasmonic nanostructures and the voltage-controlled dielectric properties of the TCO for achieving an active optoelectronic device. PLaTONE musters up a team of highly experienced researchers from both academic and non-academic institutions to tackle the issue, and provides the candidate the ideal environment for boosting his skills and assemble a solid collaboration network for future national and international funding programs.
