Insights on hexagonal TbMnO3 for optoelectronic applications: From powders to thin films

T. Fix et al.

Summary: In this study, TbMnO3 (TMO) powders were fabricated and doped with In, Lu, Gd, Sm, Nd, Y. It was found that In and Nd atoms significantly reduce the cell size while maintaining an orthorhombic structure. Epitaxially grown h-TMO, h-In-TMO, h-Y-TMO, and h-YMO were successfully obtained using pulsed laser deposition (PLD). The optical properties of the films showed a direct bandgap of 1.5-1.6 eV for h-TMO and doped h-TMO films.

d Misfit layer SnTiS3: An assemble-free van der Waals heterostructure SnS/TiS2 for lithium ion battery anode

Yue-E Huang et al.

Summary: The misfit layer SnTiS3 (STS) crystal, as a bulk van der Waals (vdW) heterostructure SnS/TiS2, has been developed as a superior anode material for lithium-ion batteries (LIBs), combining the advantages of metallic TiS2 layers and high lithium-storage SnS layers. Additionally, the use of graphene oxide (GO) for support and in-situ electrochemical reduction during the first cycling helps decrease the crystalline domain size and offers a conductive network for ions and electrons, resulting in superior electrochemical performance compared to other anode materials based on SnS or TiS2.
