Special Issue Information

Dear Colleagues,

Two-dimensional (2D) materials heterostructures have emerged as one of the most promising platforms for next-generation nanodevices. By combining different 2D layers with complementary electronic, optical, and mechanical properties, these heterostructures exhibit novel quantum effects, tunable band alignments, and strong interfacial interactions. Such unique characteristics make them highly attractive for developing advanced sensors, photodetectors, and multifunctional optoelectronic devices.

Despite the rapid progress, several challenges remain to be addressed, including scalable fabrication of high-quality heterostructures, reliable control of surfaces and interfaces, and stable integration into practical device architectures. Innovative nanomanufacturing technologies, advanced characterization methods, and theoretical simulations are, therefore, essential to bridge the gap between fundamental science and real-world applications.

This Special Issue aims to provide a platform for reporting recent advances in the design, fabrication, and application of 2D material heterostructures for sensing and optoelectronic technologies. Both original research articles and review papers are welcome. Submissions highlighting novel nanomanufacturing strategies, cost-effective device integration, and multifunctional applications are particularly encouraged.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Two-dimensional materials heterostructures for sensors and optoelectronic devices;
  • Scalable fabrication and integration of 2D materials;
  • Surface and interface engineering in layered nanostructures;
  • New nanomanufacturing and nanofabrication technologies;
  • Nanoscale simulations of heterostructures and devices;
  • New characterization techniques of 2D materials heterostructures.

Two-dimensional materials and their van der Waals heterostructures have shown great potential in quantum physics, flexible electronics, and optoelectronic devices. However, interfacial bubbles originated from trapped air, solvent residues, adsorbed molecules and reaction byproducts remain a key limitation to performance. This review provides a comprehensive overview of the formation mechanisms, characteristics, impacts, and optimization strategies related to bubbles in 2D heterostructures. We first summarize common fabrication approaches for constructing 2D heterostructures and discuss the mechanisms of bubble formation together with their physicochemical features. Then, we introduce characterization techniques ranging from macroscopic morphological observation to atomic-scale interfacial analysis, including optical microscopy, atomic force microscopy, transmission electron microscopy, and spectroscopic methods systematically. The effects of bubbles on the mechanical, electrical, thermal, and optical properties of 2D materials are subsequently examined. Finally, we compare key interface optimization strategies—such as thermal annealing, chemical treatments, AFM-based cleaning, electric field-driven approaches, clean assembly and AI-assisted methods. We demonstrate that, although substantial advances have been made in understanding interfacial bubbles, key fundamental challenges persist. Future breakthroughs will require the combined advancement of mechanistic insight, in situ characterization, and process engineering. Moreover, with the rapid adoption of AI and autonomous experimental platforms in materials fabrication and data analysis, AI-enabled process optimization and real-time characterization are emerging as key enablers for achieving high-cleanliness and scalable van der Waals heterostructures.
