Bottom-up Synthesis of Metastable 2D Hexagonal Copper(I) Iodide on Monolayer and within Bilayer Graphene
David Kaiser, Guobin Jia, Janis Köster +9
Copper(I) iodide (CuI) is a wide-bandgap semiconductor crystallizing in the 3D -phase under ambient conditions; its layered van der Waals bulk phase -CuI is stable only betwe…
Sonochemically Boosted Hydrogen Evolution Activity of Janus TMD Monolayers
Rayantan Sadhukhan, Md Tarik Hossain, Julian Picker +5
2D electrocatalysts that enable hydrogen evolution at low overpotentials offer an attractive alternative to expensive platinum-based systems. Here, we report the growth of Janus tr…
Robust phonon engineering and symmetry-selective lattice dynamics in CrSBrCl
Satyam Sahu, Arsalan Hashemi, Mahdi Ghorbani-Asl +9
Atomic substitution provides a controlled route to engineer lattice dynamics in low-symmetry two-dimensional materials. Here, by combining polarization-resolved Raman spectroscopy…
Defect migration and phase transformations in 2D iron chloride inside bilayer graphene
Qiunan Liu, Haiming Sun, Yung-Chang Lin +7
The intercalation of metal chlorides, and particularly iron chlorides, into graphitic carbon structures has recently received lots of attention, as it can not only protect this two…
Ferroelectric Domains and Evolution Dynamics in Twisted CuInP2S6 Bilayers
Dongyu Bai, Junxian Liu, Yihan Nie +4
Polar domains and their manipulation-particularly the creation and dynamic control-have garnered significant attention, owing to their rich physics and promising applications in di…
Which chromium-sulfur compounds exist as 2D material?
Affan Safeer, Mahdi Ghorbani-Asl, Wouter Jolie +3
Two-dimensional (2D) chromium-sulfides are synthesized by molecular beam epitaxy using graphene as a substrate. Structure characterization by employing scanning tunneling microscop…
