Organic-SnSe Hybrid Superlattice toward Synergistic Electrical Transport Optimization and Thermal Conductance Suppression.

Recently, layered SnSe has drawn broad research interest as a promising thermoelectric material that possesses great potential for application in energy conversion. However, extensive efforts have been devoted to optimizing the thermoelectric performance of SnSe, but the value is still far from satisfactory. Therefore, we developed an organic-inorganic superlattice hybrid by intercalating organic cations into SnSe interlayers in an attempt to enhance the thermoelectric properties.

Abnormal Out-of-Plane Vibrational Raman Mode in Electrochemically Intercalated Multilayer MoS.

Raman spectroscopy is a powerful technique to probe structural and doping behaviors of two-dimensional (2D) materials. In MoS, the always coexisting in-plane (E) and out-of-plane (A) vibrational modes are used as reliable fingerprints to distinguish the number of layers, strains, and doping levels. In this work, however, we report an abnormal Raman behavior, i.

Edge-Rich Reduced Graphene Oxide Embedded in Silica-Based Laminated Ceramic Composites for Efficient and Robust Electrocatalytic Hydrogen Evolution.

To mitigate the energy crisis and environmental pollution, efficient and earth-abundant hydrogen evolution reaction (HER) electrocatalysts are essential for hydrogen production through electrochemical water splitting. Graphene-based materials as metal-free catalysts have attracted significant attention but suffer from insufficient activity and stability. Therefore, a novel and economical approach is developed to prepare highly active, robust, and self-supported reduced graphene oxide (rGO)/SiO ceramic composites as electrocatalysts in HER.

Hybrid superlattices of two-dimensional materials and organics.

Two-dimensional (2D) materials have received extensive interest due to their exceptional properties. It is strongly required to assemble 2D materials in bulk quantities for macroscopic applications, but this is highly restricted by the aggregation of 2D materials. Constructing three-dimensional (3D) hybrid superlattices of alternating 2D materials and organic molecule layers provides a new path to access the exceptional properties of 2D materials in bulk quantities.

Flexible Foil of Hybrid TaS /Organic Superlattice: Fabrication and Electrical Properties.

TaS nanolayers with reduced dimensionality show interesting physics, such as a gate-tunable phase transition and enhanced superconductivity, among others. Here, a solution-based strategy to fabricate a large-area foil of hybrid TaS /organic superlattice, where [TaS ] monolayers and organic molecules alternatively stack in atomic scale, is proposed. The [TaS ] layers are spatially isolated with remarkably weakened interlayer bonding, resulting in lattice vibration close to that of TaS monolayers.
