¤ Team project

• Dr. Martino Aldrigo, Project manager
  
• Dr. Alexandru Muller, Mentor

¤ Objectives:

The present Postdoc project aims at achieving the following objectives.

• Choice of the best 2D material(s) for antennas and switches: the initial choice will be monolayer MoS₂, thanks to its MIT behaviour at low voltages (around 2.2 V) and to its sensitivity to temperature. This peculiar behaviour of MoS₂ will allow creating a TMA whose radiation characteristics can be tuned by an applied voltage/a temperature gradient.
• Electrical characterisation of MoS₂ and other 2D materials: the material(s) will be transferred on a bulk substrate (namely, high resistivity silicon - HRSi - and silicon dioxide - SiO₂).
• Design of a TMA based-component, i.e. 2D material-based antenna and switch, which create at the same time a „rectenna” (since the switch is essentially a diode).
• Fabrication of the TMA based-component and its experimental characterisation in DC and at microwaves.
• Fabrication and experimental characterisation of a 2D material-based TMA with up to 8 elements.
• Integration of the fabricated tag with an ad-hoc or off-the-shelf sensor (e.g. temperature or pressure). This will represent the final demonstrator of the project.

¤ Results

• Exploitation of the last (and often unknown) 2D materials, especially the so-called 2D chalcogenides, for integration with the „smart” RFID tag. In detail, 2D materials will be used for both the linear (antennas) and nonlinear (switches) components involved in the project. To the proponent’s knowledge, no solution has been proposed so far to integrate 2D materials in RFID/WSNs systems.
• Design of a „smart” RFID (semi-) passive tag, operating in the X-band (i.e. in the 8 - 12 GHz frequency range), thus extending the classical microwave range of RFID systems. The tag project will be based upon the so-called Time-Modulated Arrays (TMAs).
