Ultrastrong Au-Te bonding drives disorder in monolayer ZrTe $_{5}$ on gold

Konrád Kandrai, Zoltán Tajkov, Péter Kun +3

Monolayer ZrTe $_{5}$ is predicted to host a large-gap quantum spin Hall phase, motivating efforts to isolate single layers of the material. Gold-assisted exfoliation produces clean m…

Robust phonon engineering and symmetry-selective lattice dynamics in CrSBr $_{1 - x}$ Cl $_{x}$

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…

Surface reconstruction limited magnetism of the nodal loop semimetal Ca $_{3}$ P $_{2}$

Assem Alassaf, János Koltai, Amador García-Fuente +1

Nodal loop semimetals are topological materials with drumhead surface states characterized by reduced kinetic energy. If the Fermi energy of such a system is near these nondispersi…
