Low-Bandgap Ferroelectric <i>h</i>-LuMnO₃ Thin Films for Photovoltaic Applications.

ABSTRACT: This work explores the deposition of hexagonal (h-) LuMnO₃ thin films in the P6₃cm phase and investigates the conditions under which the synergy of ferroelectric and photoactive properties, can be achieved to confirm the potential of this material for applications in the development of next-generation photovoltaic devices. Single-phase h-LuMnO₃ was successfully deposited on different substrates, and the thermal stability of the material was confirmed by Micro-Raman spectroscopy analysis from 77 to 850 K, revealing the suitable ferro- to para-electric transition near 760 K. Optical measurements confirm the relatively narrow band gap at 1.5 eV, which corresponds to the h-LuMnO₃ system. The presence of domain structures a
