The main results (2017-2021)
IV Antonova deals with the development of new materials based on graphene with a wide range of electronic properties, namely, with the creation and study of graphene and few-layer-graphene for gas sensors, humidity sensors, transistors, vertical heterostructures created using chemically functionalized graphene and 2D printing technology.

  1. An original technology was developed and thin-film hybrid structures were created using the covalent functionalization of graphene with an organic solvent N-methylpyrrolidone (NMP) (films consisting of one or more graphene layers or a suspension. As a result, the possibility of obtaining 2D dielectric films with a high dielectric constant (~ 8-9) ultralow charge in the film (~ 1e10 cm-2), low leakage currents, which makes it promising for optoelectronic applications. It should be noted that the restoration of the conductivity of the upper layer opens up new interesting possibilities for three-dimensional design, namely, for imparting substantially different properties to different monolayers in a single structure.
  2. New technology for creating fluorographene has been proposed and implemented (simple and cheap technology, several patents have been obtained) by processing graphene or multigraphene up to several nanometers thick (films or suspension) in an aqueous solution of hydrofluoric acid. An abrupt transition from a high conductivity of the layer to a non-conductive state was found during processing for several minutes. It was found that, at a graphene fluorination degree of ~ 20-25%, it leads to the formation of arrays of graphene or multigraphene quantum dots in the fluorographene matrix. Unique investigations of the band structure of QDs by charge spectroscopy have been carried out. The system of QD levels of graphene and its dependence on the film thickness and degree of fluorination have been determined. The possibility of controlling the emission time of QD carriers by varying the initial thickness of the graphene film subjected to fluorination was found. It has been shown that dielectric films made of fluorinated graphene have an ultra-low charge in the film or heterointerface, low leakage current, and stability up to 450 ° C, which makes them promising for use as dielectric layers in van der Waals heterostructures. The possibility was shown and the conditions for fluorination of the graphene suspension were clarified. Due to the possibility of obtaining fine particles of fluorographene, films formed from a suspension of FGs have a surface relief of ~ 2 nm and, at a fluorination degree of more than 30%, they have dielectric properties and low leakage currents.
  3. Recently, the group of IV Antonova. has been developing graphene-based and functional graphene inks for 2D printing technologies. A suspension of graphene, fluorographene, V2O5, h-BN nanoparticles, and composite particles have been successfully used in 2D printing technologies to create conductive, dielectric, and functional layers, as well as memristors, sensors, and transistors.
  4. Fluorographene has been used to develop composite materials for memristors. We have printed and investigated test elements that use a stable switching resistance with an on-to-off current ratio of up to 8-9 orders of magnitude. As an active element, we used a composite of fluorinated graphene and V2O5 nanoparticles. Resistive switching up to 4-6 orders of magnitude was found for a two-layer memristive structure of fluorographene on a polyvinyl alcohol film. It was determined that in both cases the switching time is ~ 30 ns, and ensures stability during pulse switching at least up to 2e6 times.
  5. Two-layer structures of fluorinated graphene film on graphene oxide were created by 2D printing. The technology for producing graphene oxide is well developed (modified Hammers method), however, the problem of using graphene oxide as a dielectric is the instability of its properties and high leakage currents. We have shown that both problems can be solved by applying a thin layer of fluorinated graphene to the GO using printing technologies. In addition, we have created hybrid transistor heterostructures, in which dielectric layers were created by printing from fluorinated graphene, and the channel - by transferring CVD graphene or multigraphene. As a result, an increase in the mobility in the channel was observed by a factor of 4-5, which is promising for applications.
  6. Work was carried out to study the flexibility of various structures of graphene, fluorinated graphene, and composite graphene layers with PEDOT: PSS (polymer with the highest conductivity) under tensile or compressive deformations. In particular, using printing technologies, resistive moisture sensors were created from a graphene composite with PEDOT: PSS, and it was shown that the functional properties of the sensors do not change when they are stretched as a result of up to a bending radius of 3 mm (deformation ~ 2%). For humidity sensors based on CVD graphene, the types of defects leading to different signs of the sensor response were determined, which is important for optimizing the response of structures. For memristor structures made of fluorinated graphene on a film of polyvinyl alcohol, it was shown that a decrease in the ratio of currents in the open and closed states from 8-9 orders of magnitude to 2 orders occurred at tensile deformations of about 7%; after the removal of deformations, the parameters of the structures were completely restored to their initial values.
  7. The possibility of nanostructuring multigraphene with high-energy ions (Xe with energies of 20-250 MeV) with the formation of pores with a size of 20-60 nm has been shown. It was found that starting from certain values of ion energies (70 MeV), the mobility of carriers in the structured material slightly decreases in comparison with the initial one, whereas when irradiated with ions of lower energy, the mobility decreases by 2–3 orders of magnitude. Taking into account the decrease in the number of defects tested by the Raman scattering method, the effect was explained by the closure of bonds at the edges of the pores vertically between layers, which opens up prospects for nanostructuring of few-layer graphene without degradation of its electrical properties.
  8. A method was found for the synthesis of composite nanoparticles based on hexagonal boron nitride h-BN and graphene G, and the morphological and electrical parameters of films from composites of various compositions were investigated. The starting materials were synthesized in plasma and their structural quality was confirmed. By varying the composite content, it is possible to obtain films that differ in both morphological and electrical parameters. In particular, at a certain composition, G particles were detected, differently decorated with h-BN particles, which leads to the emergence of a multi-barrier system and its manifestation in electrical characteristics. With compositions, h-BN: G = 1: (4-10), nonlinear current-voltage characteristics with a hysteresis of up to 4 orders of magnitude and bandgap 18 – 27 meV are observed.
