“…Two-dimensional (2D) layered materials such as graphene (GR), hexagonal boron nitride (h-BN), and their heterostructures have recently received intensive attention due to their unique properties and possible device applications. [1][2][3][4][5] GR is a promising material as a transparent conductive electrode (TCE) for optoelectronic devices in view of its high electrical conductivity and almost-perfect transmittance in the visible region. 6,7 Insulating h-BN is highly attractive as an interfacial material between GR and semiconducting materials for heterostructures because the bandgap of h-BN is very large and its lattice mismatch with GR is very small (1.5%).…”

“…In addition to the ordinary mechanical properties, 2D materials possess many outstanding physical properties, such as electrical, magnetic, thermal, and optical properties, to name a few [ 38 ]. By further development of fabrication techniques and through assembling different 2D materials into heterostructures, these physical properties can be utilized in specific applications for novel nanoelectronics, optoelectronics, spintronics, and energy applications, as well as for medical or biomedical devices [ 59 ]. A better understanding of the mechanical properties of strained, layered 2D materials, especially heterostructures, can improve the design and fabrication of future flexible and stretchable devices and multidimensional platforms for various targeted needs.…”

The mechanical properties of engineered van der Waals (vdW) 2D materials and heterostructures are critically important for their implementation into practical applications. Using a non-destructive Raman spectroscopy approach, this study investigates the strain evolution of single-layer graphene (SLGr) and few-layered boron nitride/graphene (FLBN/SLGr) heterostructures. The prepared 2D materials are synthesized via chemical vapor deposition (CVD) method and then transferred onto flexible polyethylene terephthalate (PET) substrates for subsequent strain measurements. For this study, a custom-built mechanical device-jig is designed and manufactured in-house to be used as an insert for the 3D piezoelectric stage of the Raman system. In situ investigation of the effects of applied strain in graphene detectable via Raman spectral data in characteristic bonds within SLGr and FLBN/SLGr heterostructures is carried out. The in situ strain evolution of the FLBN/SLGr heterostructures is obtained in the range of (0–0.5%) strain. It is found that, under the same strain, SLG exhibits a higher Raman shift in the 2D band as compared with FLBN/SLGr heterostructures. This research leads to a better understanding of strain dissipation in vertical 2D heterostacks, which could help improve the design and engineering of custom interfaces and, subsequently, control lattice structure and electronic properties. Moreover, this study can provide a new systematic approach for precise in situ strain assessment and measurements of other CVD-grown 2D materials and their heterostructures on a large scale for manufacturing a variety of future micro- and nano-scale devices on flexible substrates.

“…LDMs systems enable artificial states of quantum matter as a promising solid-state platform for coherent sources of single-photon emitters, qubits, topological elements, and quantum sensors due to the coupling of spin to strain (Lemme et al, 2022). Regardless of the substrate, the layered materials are built by stacking and can create intrinsically thin (<1 nm monolayers) hybrid homo-or heterostructures (HHs) in a physical sense with preferentially oriented crystalline structures, tracing advantages for electronic devices, such as transistors and memristors, due to distinguished quantum confinement behavior (Franklin, 2015;Maggini and Ferreira, 2021;Chakraborty et al, 2022). Moreover, the control of interlayer physical interactions and immobilization of mixeddimensional and functional stacked structures result in the van der Waals nano-opto-electro-mechanical couplers (Zhang T. et al, 2022).…”

The urgent need to address the global sustainability issues that modern society is currently facing requires the development of micro and nanotechnologies, which rely largely on functional materials. Beyond studies focused solely on low-dimensional materials, broader research related to multifunctionality has shown that the major efforts to meet these criteria for new electronic, photonic, and optoelectronic concepts, particularly to achieve high-performance devices, are still challenging. By exploiting their unique properties, a comprehensive understanding of the implications of research for the synthesis and discovery of novel materials is obtained. The present article encompasses innovation research as an alternative optimization and design for sustainable energy development, bridging the scaling gap in atomically controlled growth in terms of surface heterogeneity and interfacial engineering. In addition, the corresponding research topics are widely regarded as a scientometric analysis and visualization for the evaluation of scientific contributions into the early 20 years of the 21st century. In this perspective, a brief overview of the global trends and current challenges toward high-throughput fabrication followed by a scenario-based future for hybrid integration and emerging structural standards of scalable control design and growth profiles are emphasized. Finally, these opportunities are unprecedented to overcome current limitations, creating numerous combinations and triggering new functionalities and unparalleled properties for disruptive innovations of Frontier technologies.
