Large area stacking of van der Waals heterostructure arrays, based on 2D Transition Metal Dichalcogenide semiconductors (TMDs), is achieved by an original physical deposition process utilizing Ion Beam Sputtering. Silica substrates endowed with periodically faceted nanoridges are fabricated using interference lithography and serve as templates for maskless TMD at glancing angles. This approach enables the creation laterally confined few-layer WS2 nanostripe arrays coated MoS2 films. The...
The strategic field of renewable energy production and storage requires novel nanoscale platforms that can feature competitive solar conversion properties. Photochemical reactions promote storage, such as water splitting oxygen-hydrogen evolution reactions, play a crucial role in this context. Here, we demonstrate photoelectrochemical device based on large-area (cm2) self-organized Au nanowire (NW) arrays, uniformly coated with ultrathin TiO2 films. NW arrays act both transparent...
The development of clean light-harvesting platforms and technologies is crucial in view the urgent energy environmental global challenges. Plasmonic nanoparticles show great promise applications, but their fabrication typically constrained to small-area laboratory-scale methods or highly polluting wet chemistry approaches that are not suitable for applications such as waste water recycling. In this work, we propose a self-organized method fabricate large-area (cm2, industrially scalable up...
Large area MoS 2 –WS van der Waals heterostructures have been fabricated using a physical deposition process. The type-II band alignment promotes electro-optical photoconversion and enhances organic pollutant photodissociation.
We show flat-optics photon harvesting in large-area polymeric/MoS 2 nanogrooved templates. The strong optical confinement into the ultra-thin MoS boosts photobleaching of polluting dyes, paving way for realistic photoconversion applications.
Thermal scanning-probe lithography (t-SPL) is a high-resolution nanolithography technique that enables the nanopatterning of thermosensitive materials by means heated silicon tip. It does not require alignment markers and gives possibility to assess morphology sample in noninvasive way before, during, after patterning. In order exploit t-SPL at its peak performances, writing process requires applying an electric bias between scanning hot tip sample, thereby restricting application...
Herein, a large‐area nanofabrication process is proposed for flexible, ultrathin, and ultrasmooth gold films with extraordinary electro‐optical performance, making them competitive as transparent conductive electrodes (TCEs). The approach circumvents the thermodynamic constraints associated physical deposition of thin film electrodes, where 3D growth metal dewetting delay stable percolation until deposited thickness exceeds 8–10 nm. It demonstrated that postgrowth ion irradiation procedure...
Header Two-dimensional (2D) Transition Metal Dichalcogenide semiconductors (TMDs) are a promising platform in view of developing novel generation optoelectronics devices and renewable photon to energy conversion technologies. However new ultra-compact harvesting schemes urgently required mitigate their poor absorption properties. In this work we propose flat-optic solution where few layers MoS 2 film is conformally deposited on large area (cm ) nanogrooved template. The subwavelength...
Modern photonics demands for high-resolution (HR) and deterministic lithography on transparent substrates. Thermal scanning-probe (t-SPL) is a mask-less approach that couples nanoscopic patterning resolution with the possibility to perform morphological characterizations without damaging delicate substrates unlike it happens other techniques of similar resolution. In order operate at its maximum performances, an electric bias between scanning micromachined cantilever sample needed thereby...
