Electronic Reconstruction across the Tilt-Free Transition in La$_3$Ni$_2$O$_7$

The emergence of high-$T_c$ superconductivity in pressurized La$_3$Ni$_2$O$_7$ is intimately linked to a structural transition that suppresses the tilts of the NiO$_6$ octahedra, yet its impact on the electronic structure remains poorly understood. Here, we probe the electronic response across this tilt-free transition...

Hydrostatic compression-driven lattice crossover, electronic metallization, and fermi surface reconstruction in few-layer 1T'-MoTe2

This study investigates the structural, lattice dynamic, electronic, and Fermi surface evolution of exfoliated few-layer 1T'-molybdenum ditelluride (1T'-MoTe2) under hydrostatic pressure. Using a combination of atomic force microscopy, in-situ high-pressure micro-Raman spectroscopy, temperature-dependent four-probe ele...
