Report on the design of tunable chiral graphene- and CNT-based metasurfaces/polarizers. Recommendations to executors of WP3

Homemade packages based on the Finite Difference Time Domain (FDTD) method and commercial solvers such as CST and COMSOL will be used for full wave electromagnetic analysis of the transmission and reflection coefficients, the electromagnetic modes, and the spatial distribution of the electromagnetic radiation both inside and around the structure for metamaterials/metasurfaces based on metals, dielectrics, semiconductors, graphene/CNT, and combinations of them. We will study the equilibrium morphology, electronic structure and Raman spectra, of the interface between a graphene monolayer and different utilized in project dielectric and semiconducting substrates using non-empiric quantum chemical density functional theory (DFT) simulation in the cluster approximation. Modelling of EM properties of different configuration of graphene coupled with metasurface vs their microscopic characteristics will be performed via semi-empirical methods of the computational electromagnetics. Tubability of graphene conductivity as it is and electromagnetic constituent parameters of metasurface coupled with graphene will be analysed vs highlighting with IR laser pulses and biasing.

Exploitation plan

The exploitation plans will be formulated for i providing adequate and effective protection of knowledge created in the project ii promotion of the exploitation of project results under consideration of the IPR of participants iii Implementation of their actions

Report of the characterization of the fabricated chiral metasurfaces.

The morphology of the fabricated metasurfaces will be studied by using SEM and optical microscopy techniques to reveal the relationship between sensitivity of the helicity of the THz radiation and fabrications parameters. The morphology and local electronic properties of the graphene films deposited on the top of the metasurface will be studied in-situ by using STM and STS in order to verify the thickness of the films, their substrate coverage and presence of defects. In addition, ARPES will be employed for studing the bandstructure of the deposited graphene sheet. The polarization-sensitive reflection and transmission of the fabricated structures in the THz the frequency range from 100 GHz to 3 THz will be performed by time domain terahertz spectrometer (EKSPLA, Vilnius Lithuania) based on femtosecond laser (wavelength 1 μm, pulse duration less than 150 fs) and GaBiAs photoconductive switch as THz emitter and detector. The polarization sensitive transmittance will be measured by using the optical rectification and free-space electro-optic sampling with ZnTe crystals and two wire grid polarizers before and after the sample. As a reference of reflectivity measurement, an aluminum mirror is replaced in the same position as the sample.

Report on fabricated chiral metasurfaces by femtosecond micromachining and lithographic techniques; metasurfaces made on vertically aligned carbon nanotubes. Feedback to WP1 for design optimization.

Single layer chiral metasurfaces will be fabricated by writing arrays of chiral “meta-atoms” on the surface or subsurface layer of the dielectric and semiconductor substrates. The multi-layer structures will be fabricated by layer-by-layer writing via changing the position of the focal plane withing the substrate. The enhancing the rotatory power of the measurface will be performed by rotating substrate thus forming Moire patterns. The lithographic techniques will be used for formation of the chiral arrays of metal nanoparticles on the surface. Arrays of GaN HMETS plasmonic resonators will be grown using MBE method.
