Mudellides

Mudellides are a hypothetical class of nanoscale, layered materials conceived in theoretical studies of emergent electronic states. The term mudellide is used to describe quasi-two-dimensional assemblies that exhibit configurable band structures due to interlayer coupling and lattice distortions. The name blends "mud" and the common suffix "-lide" used in minerals and minerals-like compounds, reflecting their proposed layered nature. In proposed models, mudellides form when two or more semi-metallic or insulating layers are held at a precise misalignment or undergo a controlled interfacial reaction, producing moiré patterns that give rise to flat electronic bands and strongly correlated states.

Properties: Mudellides are predicted to have tunable conductivity, anisotropic charge transport, and compatibility with mechanical strain. They may host topological edge modes, superconducting-like pairing at elevated temperatures in theory, and adjustable dielectric response for photonic applications.

Synthesis and observation: There is no experimental evidence as of now. The concept has emerged from theoretical work and computer simulations exploring moiré superlattices and interfacial phenomena in van der Waals stacks. Experimental verification would require advanced fabrication techniques such as molecular-scale layer control, precise rotational alignment, and sensitive spectroscopy.

Applications and status: If realized, mudellides could enable customized electronic materials and adaptive optics. However, the field remains speculative, with significant questions about stability, reproducibility, and scalability.
