Raman Evidence of Moiré Diamondene Formation by High‐Pressure

Advanced Science, EarlyView.
Two‐dimensional moiré diamondene is formed at approximately 2 GPa through the synergy of high pressure, interlayer twist, and a chemically active diamond (100) surface. It is a hybrid sp2–sp3 nanostructure, consists of localized nanodiamond domains and unbonded graphene segments.

High‐Pressure Modulation of Breathing Kagome Lattice: Cascade of Lifshitz Transitions and Evolution of the Electronic Structure

Advanced Science, EarlyView.
External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...
