Special Issue Information

Dear Colleagues,

The successful preparation of graphene in 2004 rapidly aroused a global upsurge of research into 2D structured materials. The emergence of many new 2D materials in low-dimensional systems has attracted the continuous attention of many researchers. The unique planar crystal structure of 2D materials endows them with versatile physical properties, and the 2D material family covers almost all the electrical, optical, mechanical, thermal, and magnetic properties involved in bulk materials, providing a host of questions for future research to explore novel physical phenomena and applications.

We are pleased to invite researchers to contribute to this Special Issue concerning the synthesis, properties, and application of 2D structured materials. This Special Issue aims to discuss the properties and structures of these materials and to widen the community’s fundamental understanding of their use. Potential topics include, but are not limited to:

  • Novel synthesis methods and developments related to 2D materials and their heterostructure;
  • Experimental and theoretical exploration of the growth mechanism for 2D materials;
  • Electrical, optical, mechanical, thermal, and magnetic properties of 2D materials and structures;
  • Device applications of 2D materials and their heterostructures in electronics, optoelectronics, energy, flexible sensors, transistors and other functional devices;
  • Electronic, magnetic, and structural phase transitions of 2D materials under extreme conditions;
  • Novel applications of 2D structured materials;
  • Moiré superlattices and related moiré excitons in twisted van der Waals heterostructures.

In this Special Issue, original research articles, review papers and communication-type papers are all welcome.

In this paper, we design a frequency reconfigurable antenna for terahertz communication. The antenna is based on a Yagi design, with the main radiating elements being a pair of dipole antennas printed on the top and bottom of a dielectric substrate, respectively. The director and reflector elements give the antenna end-fire characteristics. The ends of the two arms of the dipole are constructed by staggered metal and graphene parasitic patches. By utilizing the effect of gate voltage on the conductivity of graphene, the equivalent length of the dipole antenna arms are altered and thereby adjust the antenna’s operating frequency. The proposed reconfigurable hybrid Yagi–Uda antenna can operate in five frequency bands separately at a peak gain of 4.53 dB. This reconfigurable antenna can meet the diverse requirements of the system without changing its structure and can reduce the size and cost while improving the performance. Full article

Bilayer graphene exhibits intriguing physical and mechanical properties that are suitable for advanced electronic device applications. By introducing a new degree of freedom through interlayer twisting, exotic phenomena such as superconductivity can arise. However, in practical experiments, manual manipulation is often required to fabricate such a configuration and therefore, scaled production of magic angle bilayer graphene is challenging. In this work, we propose utilizing the grain boundaries and accompanying localized out-of-plane deformation in graphene to facilitate twisted bi-layer graphene formation. Based on molecular dynamics simulations, the structure folding process along the boundary line is examined where a lower energetic cost is found. Once stabilized, the folded bilayer structure shows twist angles that differ visibly from the conventional AA or AB stacking modes and can achieve twist angles close to the 1.1° magic angle. This observation suggests a potential novel strategy for synthesizing stable twisted bilayer graphene or other two dimensional van der Waals heterostructures with greater efficiency. Full article

A supercapacitor’s energy storage capability is greatly dependent on electrode materials. Layered double hydroxides (LDHs) were extensively studied as battery-type electrodes because of their 2D structure and quick intercalation/deintercalation of electrolyte ions. However, the energy storage capability for pristine LDHs is limited by their large aggregation tendency and poor electrical conductivity. Herein, a novel NiCoMn-LDH/SWCNTs (single-walled carbon nanotubes) composite electrode material, with ultrathin NiCoMn-LDH nanosheets dispersedly grown among the highly conductive networks of SWCNTs, was prepared via a facile zeolitic imidazolate framework-67 (ZIF-67)-derived in situ etching and deposition procedure. The NiCoMn-LDH/SWCNTs electrode demonstrates a specific capacitance as large as 1704.3 F g−1 at 1 A g−1, which is ascribed to its exposure of more active sites than NiCoMn-LDH. Moreover, the assembled NiCoMn-LDH/SWCNTs//BGA (boron-doped graphene aerogel) hybrid supercapacitor exhibits a superior capacitance of 167.9 F g−1 at 1.0 A g−1, an excellent energy density of 45.7 Wh kg−1 with a power density of 700 W kg−1, and an outstanding cyclic stability with 82.3% incipient capacitance maintained when subjected to 5000 charge and discharge cycles at the current density of 10 A g−1, suggesting the significant potential of NiCoMn-LDH/SWCNTs as the electrode material applicable in supercapacitors.

Due to their high refractive index, record optical anisotropy and a set of excitonic transitions in visible range at a room temperature, transition metal dichalcogenides have gained much attention. Here, we adapted a femtosecond laser ablation for the synthesis of WSe2 nanoparticles (NPs) with diameters from 5 to 150 nm, which conserve the crystalline structure of the original bulk crystal. This method was chosen due to its inherently substrate-additive-free nature and a high output level. The obtained nanoparticles absorb light stronger than the bulk crystal thanks to the local field enhancement, and they have a much higher photothermal conversion than conventional Si nanospheres. The highly mobile colloidal state of produced NPs makes them flexible for further application-dependent manipulations, which we demonstrated by creating substrates for SERS sensors. Full article

Graphene oxide (GO), a pivotal derivative of graphene, has revolutionized nanotechnology with its tunable physicochemical properties and interdisciplinary applications in energy storage, environmental remediation, and biomedicine. Despite its exponential research growth, existing reviews remain fragmented, lacking holistic insights into evolving synthesis–application linkages, global collaboration patterns, and emerging convergence trends. This study bridges these gaps through a scientometric analysis of 14,124 peer-reviewed articles (2022–2025) from the Web of Science Core Collection, utilizing CiteSpace for co-occurrence network mapping, burst detection, and cluster analysis. Key findings reveal (1) a thematic shift from traditional synthesis optimization (e.g., Hummers’ method) toward driven material design and sustainable applications like GO membranes for water purification; (2) China’s dominance in publication output (38.5%) contrasts with the U.S. and Europe’s leadership in global collaborations; (3) interdisciplinary journals such as Chemical Engineering Journal (centrality: 0.25) and emerging clusters like “circular economy” signal transformative priorities; and (4) critical gaps in scalability, ecological safety, and cost-effective production hinder industrial translation. This work provides a roadmap for aligning research with sustainability goals, fostering global partnerships, and accelerating innovations in scalable nanotechnology. Full article
