Heterodimensional Superlattices: Preparation, Properties, and Applications

• • Heterodimensional superlattices integrate materials of different dimensionalities (0D, 1D, 2D) to achieve unique electronic structures and inter-dimensional coupling, enabling properties not accessible in conventional homodimensional heterostructures. • • Advanced preparation methods, including van der Waals assembly and phase engineering, allow precise control over layer stacking and interfacial interactions, overcoming limitations of traditional epitaxial growth for mismatched lattices. • • These superlattices exhibit tunable electronic band structures and enhanced spin-orbit coupling, leading to emergent transport phenomena such as the in-plane Hall effect, which are critical for developing next-generation spintronic devices. • • Applications in energy storage and conversion benefit from improved ion transport and catalytic activity due to the heterodimensional architecture, offering potential for high-performance batteries and electrocatalysts.
