Scalable solution-phase epitaxial growth of symmetry-mismatched heterostructures on two-dimensional crystal soft template.

ABSTRACT: Epitaxial heterostructures with precisely controlled composition and electronic modulation are of central importance for electronics, optoelectronics, thermoelectrics, and catalysis. In general, epitaxial material growth requires identical or nearly identical crystal structures with small misfit in lattice symmetry and parameters and is typically achieved by vapor-phase depositions in vacuum. We report a scalable solution-phase growth of symmetry-mismatched PbSe/Bi₂Se₃ epitaxial heterostructures by using two-dimensional (2D) Bi₂Se₃ nanoplates as soft templates. The dangling bond-free surface of 2D Bi₂Se₃ nanoplates guides the growth of PbSe crystal without requiring a one-to-one match in the atomic structure, which exerts mi
