Symposium EL09-2Ds Go Hybrid—Properties and Applications of Dimensionally Hybrid Systems

2D materials have the potential to revolutionize current technologies through on-chip integration of ultra-thin semiconductors with layer-dependent band structure and strain-tunable functional properties. The scientific community has explored the fabrication of planar 2D stackings for applications in photonics, optoelectronics, straintronics, valleytronics and twistronics, unlocking wide knowledge of the integration of 2D materials on different substrates and paving the way for more elaborate heterostructures. Which novel avenues can be unveiled in semiconductor stackings having different dimensionalities?
This symposium will gather the semiconductor and the 2D material communities to discuss the challenges and opportunities of non-planar heterostructures based on 2D materials. There will be a particular focus on dimensionally hybrid semiconductor heterostructures (2D/1D and 2D/0D systems), as well as heterostructures based on different 2D materials and on how recent research progress can improve existing and novel technologies in different application areas. The topic will be addressed with an interdisciplinary approach to maximize its impact and the generation of new ideas will be ensured by including researchers from related, but distinct subareas. The following topics are of particular interest: (i) Impact of morphology and chemistry of the individual components on the properties of the hybrid structure; (ii) Dimensionally mixed interfaces: surface confinement in 2D/1D and 0D stacking; (iii) High space- and/or time- resolution characterization techniques applied to hybrid structures; (iv) Experimental observation of 1D and 0D component-induced variation in parameters such as strain and the effects on optical and electronic response; (v) Charge and energy transfer in hybrid heterostructures; (vi) Insights into the integration process of multidimensional systems; (vii) Dimensionally hybrid systems that combine semiconducting with other properties such as magnetism. Contributions are also sought that advance understanding and control of quantum properties in 2Ds, envisioned to be coupled with other semiconductors for emerging areas where 2D materials show promising properties applicable in functional technologies.

Topics will include:

  • Relevant synthesis aspects for hybrid heterostructuring and high-throughput integration processes
  • Chemical, structural, and property characterization at multiple length scales, with high spatial and temporal resolution
  • Interplay between dimensional mismatching, defects and strain distribution in the 2D component and impact on the overall functional behavior
  • Environmental perturbations: effect of the environment on the functional properties in vacuum, controlled atmosphere and standard conditions.
  • Quantum properties in dimensionally hybrid heterostructures
  • Fundamental and technological limits in fabrication scalability
  • Hybrid systems beyond semiconductors (e.g., superconductor, magnetic ordering, 2D magnets) and their integration with other low dimensional materials
  • Towards electronic, optoelectronic, photonic, energy conversion and sensing applications
  • A tutorial complementing this symposium is tentatively planned.
