Coherent, atomically thin transition-metal dichalcogenide superlattices with engineered strain (original) (raw)
AI-generated Abstract
Coherent atomically thin superlattices of transition metal dichalcogenides (TMDs) have been developed, exhibiting engineered strain that facilitates optical property tuning. Using an omnidirectional epitaxial growth technique, these superlattices maintain lattice coherence despite significant mismatches, achieving notable shifts in photoluminescence peaks. The work introduces theoretical models addressing the mechanisms of strain-induced ripple formation, providing insights into the energetic interplay affecting property modulation in TMD monolayers.
