The work demonstrated in this thesis represent the path towards developing the large-scale fabrication of two-dimensional nanoporous membrane devices and use thereof as platforms to study nanoscale physics of water and ion flow through confined channels. M ...
Biologically inspired solid-state nanopores are artificial openings or apertures in thin membranes similar to natural protein ion channels in a lipid bilayer of cell membranes. In solid-state nanopores, a thin insulating membrane with single or multiple po ...
A recent 2D spinFET concept proposes to switch electrostatically between two separate sublayers with strong and opposite intrinsic Rashba effects, exploiting the spin-layer-locking mechanism in centrosymmetric materials with local dipole fields. Here, we p ...
Two-dimensional materials (2DM) have emerged as potential candidates for low power electronics, optoelectronics, and sensing [1]. However, the chemical and physical processes involved in conventional lithography methods, have shown detrimental effects on 2 ...
Recently, two-dimensional (2D) material based gas sensing, especially transition metal dichalcogenide-based sensing, has been widely investigated thanks to its room temperature sensing ability. Unlike metal oxide based sensors, 2D material-based sensing ca ...
Van der Waals heterostructures (vdWHSs) enable the fabricationof complex electronic devices based on two-dimensional (2D) materials.Ideally, these vdWHSs should be fabricated in a scalable and repeatableway and only in the specific areas of the substrate t ...
The objective of this semester project is to investigate different fabrication processes and materials used for the fabrication of piezoelectric electrodes. More in detail, to investigate if the use of test wafers and high resistivity wafers play a role on ...
The fabrication of metallic nanostructures on stretchable substrates enables specific applications that exploit the combination of the nano-scale phenomena and the mechanical tunability of the physical dimensions of the nanostructures. Due to the large dif ...
Cantilever beams are used as mass sensing device of chemical analyte by measuring the shift in frequency. However there resolution is linked to their size. As it become increasingly hard to produce smaller device an alternative is to use mode localisation ...
Since straining semiconductors can enhance the carriers’ mobility and thus improve optoelectronic properties, this project aims at determining whether t-NIL can be used in order to strain thin flakes of MoS2 out of the plane. In this approach, the thin fla ...
