The development of next-generation solid state ion conductors hinges on an understanding of microscopic diffusion mechanisms and the identification of roadblocks along macroscopic diffusion pathways (e.g., intragrain defects and grain boundaries). (more…)

Call for Papers

The ECS Journal of Solid State Science and Technology is publishing a focus issue on molecular electronics. It also includes selected papers from the 10th International Conference on Molecular Electronics held from November 29–December 2, 2021, in Lyon, France. The first International Conference on Molecular Electronics (ElecMol) was organized in 2004. Three successful conferences in 2004, 2005, and 2006 led to scheduling this event biennially. Molecular electronics is a widely interdisciplinary field at the frontiers of chemistry, physics, biology, electronics, and their many interfaces. The design and use of electronic components and devices at the nanometer scale stands as a major challenge for the near future.

This virtual issue focuses on papers covering the following topics: 

• Single Molecule Junctions: Memories and Switches
• Large Area Junctions: Memories and Switches
• Organic Electronics and Spintronics: Molecules and Devices
• Organic Optoelectronics and Photonics: Molecules and Devices
• 2D Systems, Nanotubes, Nanowires, Nanosheets
• Self-Assembly and Supramolecular Architectures
• Scanning Probe Microscopies and Near Field Approaches
• Carrier Transport and Device Theoretical Simulation and Modelling

Reviews, critical reviews, and perspective papers are welcomed. (more…)

During battery (dis)charging, lithium (de)intercalation in electrodes is usually spatially non-uniform across multiple length scales. Such a phenomenon is a major impediment to battery performance and life as it causes energy under-utilization and induces over-(dis)charging, etc. While reaction heterogeneity is often attributed to mass transport limitation, this talk highlights the important roles of thermodynamic factors including elastic energy and phase transformations, the understanding of which is important for the development of mitigation strategies. Through combined modeling and characterization, how stress could destabilize the lithium (de)lithiation front in single crystalline and polycrystalline intercalation compounds is elucidated. Also, a fundamental driving force for dendrite growth on the lithium metal anode during electrodeposition is provided. Stress relief thus offers a promising approach to improving reaction uniformity at the particle level. At the cell level, the reaction distribution that within the porous electrode is strongly influenced by how the electrode’s equilibrium potential varies with the state of charge, is discovered. Two types of prototypical reaction behavior emerge from common electrode materials with significant impact on the thick electrode performance. This finding leads to an efficient analytical model for optimizing battery configurations in place of common battery cell simulations. (more…)
