1T‐to‐2H Phase Evolution During Epitaxial Growth of Transition Metal Dichalcogenides

ABSTRACT Polymorphism in transition‐metal dichalcogenides is typically defined based on the post‐growth phase (1T or 2H) or stabilized heterophase structures. Transient 1T‐to‐2H phase evolution is demonstrated during epitaxial growth of MoS 2 and WSe 2 on sapphire by metalorganic...

Lattice dynamics and complete polarization analysis of Raman-active modes in LaInO 3

In this study, we present a comprehensive analysis of the Raman-active phonon modes in orthorhombic LaInO 3 based on a combination of polarization-angle resolved Raman spectroscopy and density functional theory calculations. By using backscattering from multiple crystallographic...
