Nature Materials published a review on the modular synthesis of chemically programmable superlattices, detailing how two-dimensional atomic crystals host self-assembled interlayers to create artificial quantum solids. Researchers from the University of California Los Angeles, Nankai University, and Shandong University authored the paper, which was published online on July 29, 2026.
Two-dimensional atomic crystals feature non-bonding van der Waals gaps between their crystalline atomic layers. These gaps allow selected atoms or molecules to intercalate. When confined inside the van der Waals gaps, the intercalants self-assemble into ordered interlayers between adjacent two-dimensional atomic lattices, forming intercalated superlattices.
The resulting structures combine the intrinsic properties of solid-state two-dimensional atomic crystals with the chemically programmable electronic, optical, and magnetic functionalities of the self-assembled interlayers. Nature Materials reported that these superlattices can integrate disparate quantum and collective phenomena, enabling device functionalities beyond the reach of conventional heterostructures.
Synthesis Challenges
Synthesizing intercalated superlattices with specific functions is more complex than arbitrarily combining two-dimensional atomic crystals with functional intercalants. Electronically, optically, or magnetically active interlayers are inherently more reactive than passive species. Consequently, active interlayers are frequently incompatible with conventional chemical or electrochemical intercalation strategies.
The publication classifies the functional building blocks used to construct functional intercalated superlattices while examining key challenges and emerging assembly strategies. The stated goal of the work is to establish guiding principles for the modular design and synthesis of superlattices with tailored electronic, optical, magnetic, and quantum functionalities.
