Special Issue Information

Dear Colleagues,

The rise of two-dimensional (2D) materials has placed nanofabrication and nanomanipulation at the forefront of modern materials science. These precision techniques—encompassing both bottom-up synthesis and top-down assembly—are essential for achieving atomic-level control over materials like Xenes (graphene, black phosphorus, etc.), transition metal dichalcogenides and MXenes, monolayers of covalent (COFs), and metal–organic frameworks (MOFs), etc. This control is critical for realizing their full potential, especially when constructing complex van der Waals (vdW) heterostructures.

This Special Issue aims to capture the latest advances in nanomanipulation and nanofabrication technologies for 2D materials. Our scope covers the development of new methods (synthesis, transfer, patterning) and the fundamental and applied research on 2D nanomaterials and devices prepared using these techniques.

Progress in this area is a foundational requirement for numerous cutting-edge fields, including the following:

  • Electronics (e.g., advanced transistors);
  • Optoelectronics (e.g., highly efficient photodetectors and LEDs);
  • Quantum Technologies (e.g., Moiré superlattices and twistronics);
  • Sensing (e.g., ultra-sensitive gas and biosensors);
  • Flexible Devices.

We welcome all papers that detail the nanofabrication and nanomanipulation of 2D materials, whether through the development of new methods, the demonstration of new heterostructures, or the study of devices prepared in such ways. We invite research articles, communications, and comprehensive reviews.

Gold-assisted exfoliation is an effective approach to obtain clean and large-area monolayers of transition metal dichalcogenides, yet the microscopic evolution of interfacial adhesion remains poorly understood. Here, we investigate temperature-controlled exfoliation of MoS2 between 30 and 170 °C. Based on optical microscopy image analysis, mild heating slightly improves the exfoliation yield, which is associated with the release of interfacial contaminants and trapped gases—these substances enhance the adhesion between gold and molybdenum disulfide (Au-MoS2). Unexpectedly, as revealed by AFM, SEM-EDS, and Raman analyses, parts of the Au film start to peel off from the underlying Ti adhesion layer at approximately 100 °C. This Au film detachment, resulting from the surprisingly weak Au-Ti adhesion, serves as a unique probe for interfacial strength: it preferentially occurs at the boundaries of MoS2 flakes, indicating that the reinforcement of the Au-MoS2 interaction originates at the edges rather than being uniformly distributed. At higher temperatures (>130 °C), Au detachment expands to larger areas, indicating that boundary-localized adhesion progressively extends across the entire interface. Additional STM/STS measurements further confirm that thermal annealing improves local Au-MoS2 contact by removing interfacial species and enabling surface reconstruction. These findings establish a microscopic picture of temperature-assisted exfoliation, highlighting the dual roles of interfacial contaminant release and boundary effects, and offering guidance for more reproducible fabrication of high-quality 2D monolayers.
