2019 MRS Fall Meeting & Exhibit

Symposium MS02-Mechanically Coupled and Defect-Enabled Functionality in Atomically Thin Materials

Local (e.g. defect structures) and global (e.g. mechanical stress) nonequilibrium is generally difficult to control and characterize yet offers unprecedented ability to control a host of material properties in advanced technological applications such as quantum photonics, nano electronics, electrocatalysis, and energy conversion. As one example, unprecedented opportunity for dynamic property modification can be found in atomically thin materials due their ability to experience elastic strain on the order of several percent without releasing that energy via dislocation formation or other inelastic relaxation mechanisms. Mechanically coupled and defect-enabled phenomena also allow for new functionalities and device architectures previously unachievable, such as well-defined single photon source generation and adaptive optoelectronic components and sensors.

Given the impressive recent developments in this field, this symposium will promote communication and collaboration among interdisciplinary researchers working on modifications of the intrinsic materials physics of 2D materials through strain and defect engineering. It will mainly focus on beyond-graphene 2D materials as well as the synthesis, materials physics, and applications enabled by emergent strain- and defect-enabled phenomena in these materials.

Topics will include:

  • Role of strain coupling and defects in modifying physico-chemical properties of 2D materials such as electronic band gap, carrier mobility, piezoelectric effects, magnetism, optical, thermal, thermoelectric, and catalytic/electrochemical (e.g. hydrogen evolution reaction)
  • Computational and theoretical approaches to model/predict defect-enabled and strain-coupled behavior in 2D materials
  • Advancements in the development of new computational methodologies, experimental techniques, and synthesis strategies for deterministic creation of defect- and strain-engineered 2D materials
  • Device-level performance relationships including predictions or demonstration of nanoscale architectures & heterostructures whose behavior benefits from strain coupling or defect structures
