This collection aims to highlight recent advances in the discovery, design, and functionalization of two-dimensional (2D) materials, including transition metal chalcogenides (TMCs), MXenes, phosphorene, their heterostructures, and quantum dots, for next-generation electronic, optoelectronic, and sensing systems.

We welcome contributions exploring theoretical, computational, and experimental investigations into the electronic, magnetic, optical, and thermal properties of 2D materials, with a strong emphasis on their integration into functional devices and engineered systems. Studies that leverage advanced spectroscopic techniques or first-principles modeling are especially encouraged, given their relevance to understanding structure–property relationships in both organic–inorganic hybrid systems and low-dimensional quantum materials.

Topics of interest include, but are not limited to:

- Data-driven and AI-assisted materials discovery and design

- Optoelectronic characterization and photonic behavior

- Synthesis and fabrication techniques tailored for device applications

- 2D materials in flexible electronics, bioelectronics, and quantum devices

- Electronic and optical sensors

- Nanostructures and hybrid systems for energy-efficient applications

This collection seeks to bridge fundamental materials research with practical applications in areas such as microelectronics, quantum electronics, circuit integration, and electronic materials—supporting the broader advancement of systems engineering, instrumentation, and applied electronic technologies.
