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.
Report on the THz modulator prototype performance. Experimental tests based on the feedback from WP4 (s’ouvre dans une nouvelle fenêtre)Based on the results of WP3, WP4 chiral metasurfaces will be optimized in terms of footprint, response time, modulation depth and tunability and THz modulator prototype will be fabricated.
Report on the controlling the helicity-sensitive transmission of the chiral metamaterial by irradiation with femtosecond laser pulses (s’ouvre dans une nouvelle fenêtre)To probe ultrafast relaxation dynamics including charge transfer between layers forming the chiral metasurface, we will employ multi-color pump-probe spectroscopy with ~100 fs temporal resolution. By measuring the pump induced transient changes in absorption spectrum, we will also be able to probe the evolution of charge distribution in particular material (single-layer) and the whole metasurface in a wide (near IR-VIS) spectral range. To observe light-induced transmission change employ developed at IPST system, which can measure the THz polarization change that occurs in a very wide time scale spanning from femtoseconds to nanoseconds. By irradiating the chiral metasurface containing photosensitive (e.g. silicon) layer with femtosecond laser pulses we will study the temporal evolution of the helicity-sensitive THz transmission for different polarization states of the excitation beam.
Exploitation plan (s’ouvre dans une nouvelle fenêtre)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. (s’ouvre dans une nouvelle fenêtre)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. (s’ouvre dans une nouvelle fenêtre)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.
Report on the rotatory power chiral metasurfaces and its control by external stimuli. Recommendations to executors of WP3 (s’ouvre dans une nouvelle fenêtre)The measurements will be performed by using ultra-highly sensitive THz polarization measurement system developed at the IPST based on a GaP(111) nonlinear crystal for detection and Yb-based regenerative amplifier (100kHz, 190fs, 6W, PHAROS, Light Conversion), which is employed as a femtosecond light source for THz. The three-fold rotational symmetry of the nonlinear crystal and polarization modulation for probe beam by piezo elastic modulator enables fast and accurate measurement of the polarization state of the transmitted and reflected THz radiation. In order to achieve the helicity-sensitive modulation of the THz radiation we will fabricate gammadion-type chiral film covered by dielectric (e.g. alumina) spacer followed by graphene sheet. On top of the graphene, the solid electrolyte (e.g. PEO:LiClO4) will enable the electric field control of the graphene Fermi level and hence the surface conductivity.
CHARTIST website will be set to report on the project results, dissemination, communications activities and outreach.
