Metrics & MoreArticle RecommendationsCONSPECTUS: Since the ground-breaking achievement of successfully exfoliating singlelayer graphene in 2004, there has been significant and rapid development in the field of twodimensional (2D) nanomaterials. In the field of materials science, 2D nanomaterials are defined as freestanding nanomembranes with a thickness below 100 nm and other lateral dimensions that can extend to the millimeter scale or beyond. These materials exhibit exceptional mechanical, physical, and chemical properties due to their extremely high surface area to volume ratios, surpassing those of their bulk counterparts. As a result, numerous topdown and bottom-up methods have emerged over the past decades to synthesize novel 2D nanomaterials, catering to diverse applications. In this Account, we review the existing topdown methods, such as mechanical compression and mechanical exfoliation, as well as bottomup methods including hydrothermal induction/solvothermal synthesis, chemical vapor deposition synthesis, etc. We critically discuss the advantages and limitations of each method. Subsequently, we highlight our recently developed method known as polymer surface buckling enabled exfoliation (PSBEE). Unlike previous synthesis techniques, PSBEE is based on the chemical reaction between metals and polymers to fabricate 2D nanomaterials with unique nanostructures. This approach offers a simple, efficient, cost-effective, and environmentally friendly means of achieving large-scale production of 2D nanomaterials, featuring an extremely high lateral size to thickness ratio ranging from 10 6 to 10 7 . Notably, PSBEE eliminates the need for chemical etching and enables precise control over the morphology of the synthesized nanomaterials, allowing for transitions from 2D nanomembranes to 1D nanotubes. Through thermal annealing, some of the PSBEE-fabricated 2D nanomaterials, such as 2D gold nanomaterials, can undergo pyrolysis and transform into 0D gold nanoparticles. Furthermore, the versatility of PSBEE extends beyond 2D metallic nanomaterials to the synthesis of 2D ceramic nanomaterials, showcasing its broad applicability across diverse material systems. The unique nanostructures of PSBEE-fabricated 2D nanomaterials, usually featuring a network of nanosized ceramics and metals, contribute to their exceptional mechanical and functional properties. These include an outstanding elastic strain limit, superb strength, remarkable plasticity, superior fracture toughness, high electrocatalytic properties, and unique triboelectric performance. Consequently, these properties lead to novel applications of the PSBEE-fabricated nanomaterials, such as triboelectric sensing and 2D electrocatalysis. At the same time, the PSBEE method also offers notable advantages in terms of scalable production, high throughput efficiency, and low energy consumption, making it highly suitable for future industrial applications. In general, polymer-based fabrication of 2D nanomaterials opens up possibilities for producing diverse and technologica...

“…3D semiconductor nano-and micro structures based on the folding and rolling of strained heterostructures have been reviewed in the past [11,12,19,39] and some attention has been given to their use as WGM resonators-either in the III-V material system or in other materials [19,[40][41][42][43]. Nevertheless, these reviews focus on the physical properties of the WGM resonators and their possible use as devices [40,42,43]. One aspect that is little discussed but offers a great potential for physics study and device tailoring is the strain-induced change of the optical properties of the emitters integrated into the initial heterostructure due to the roll-up process.…”

Rolled-up tubes based on released III-V heterostructures have been extensively studied and established as optical resonators in the last two decades. In this review, we discuss how light emitters (quantum wells and quantum dots) are influenced by the inherently asymmetric strain state of these tubes. Therefore, we briefly review whispering gallery mode resonators built from rolled-up III-V heterostructures. The curvature and its influence over the diameter of the rolled-up micro- and nanotubes are discussed, with emphasis on the different possible strain states that can be produced. Experimental techniques that access structural parameters are essential to obtain a complete and correct image of the strain state for the emitters inside the tube wall. In order to unambiguously extract such strain state, we discuss X-ray diffraction results in these systems, providing a much clearer scenario compared to a sole tube diameter analysis, which provides only a first indication of the lattice relaxation in a given tube. Further, the influence of the overall strain lattice state on the band structure is examined via numerical calculations. Finally, experimental results for the wavelength shift of emissions due to the tube strain state are presented and compared with theoretical calculations available in literature, showing that the possibility to use rolled-up tubes to permanently strain engineer the optical properties of build-in quantum emitters is a consistent method to induce the appearance of electronic states unachievable by direct growth methods.
