  • Researchers uncover a bulk-to-surface mass exchange mechanism in β-NiAl that drives surface phase separation, forming Ni-rich γ′-Ni3Al precipitates. This reveals how thermal defect dynamics govern intermetallic stability under high-temperature conditions.

  • Neel domain walls are typically stabilized by an interfacial Dzyaloshinskii-Moriya interaction, with a chirality that is fixed by the sample materials. Here, Song, Huang and coauthors demonstrate the existence of two bistable Néel domain wall states with opposite chiralities, and the switching between these via magnetic field pulses

  • Hydrogen-doping driven metal to ferroelectric phase transition in a complex oxide NdNiO3 is demonstrated. Transient negative differential capacitance and implementation of polarization decay into neural network for learning are then presented.

  • Borophene, a two-dimensional boron sheet, can adopt a variety of polymorphic structures that are predicted to possess interesting and potentially useful electronic properties. Micrometre-scale single-crystal borophene domains have now been grown on a square-lattice Cu(100) surface. The resulting boron sheets feature a rectangular unit cell, intrinsic stripe modulations and an unusual electron band structure.

  • A quest to resolve ultra-high vacuum synthesis of high-quality, single-crystalline metal oxide thin films containing hard-to-oxidize metals reveals a hidden role of epitaxial strain on the metal oxidation chemistry and resulting thin-film growth.

  • The many strongly interacting degrees of freedom in transition metal oxides make it difficult to capture and describe the nature of their metal-insulator transitions. Li et al. show that a resonant magnetic X-ray nanoprobe gives access to local critical behavior that is difficult to detect otherwise.

  • The nanoscale patterning of two-dimensional materials offers the possibility of novel optoelectronic properties; however, it remains challenging. Here, Camilli et al. show the self-assembly of large arrays of highly-uniform graphene dots imbedded in a BCN matrix, enabling novel devices.

  • The origin of large mobility modulation in ultrathin oxide transistors, promising for their high on-off ratio, remains mostly unknown. Here, a 106 gate-induced mobility modulation in 3.5 nm-thick TiOx transistors is explained by a high density of tail states, mediating variable range hopping of carriers.

  • Dispersionless flat bands are often required to observe unusual quantum states of matter. Here, angle-resolved photoemission spectroscopy (ARPES) reveals a flat band electronic structure in a VSe2/Bi2Se3 heterostructure, and exhibits complex circular dichroism.
