Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Entanglement spectroscopy of anomalous surface states
Physical Review ResearchWe study the entanglement spectra of surface states of symmetry-protected topological phases. The topological bulk imprints the surface with an anomaly that does not permit it to form a trivial “vacuum” state that is gapped, unfractionalized, and ...

Advanced Functional Materials, EarlyView.Self‐aligned gate transistors are developed with a single‐step dielectric passivation and fine‐tuning of source/drain electrode work function using phosphonic acid self‐assembled monolayers (SAM). This transistor architecture minimizes overlap capacitances and access resistance.

Strongly irreducible surface automorphisms [PDF]
arXiv, 2002 A surface automorphism is strongly irreducible if every essential simple closed curve in the surface has nontrivial geometric intersection with its image. We show that a three-manifold admits only finitely many inequivalent surface bundle structures with strongly irreducible monodromy.

On surfaces in digital topology
, 1995 In R. Ayala, E. Domínguez, A.R. Francés, A. Quintero, J. Rubio. A Polyhedral Approach to Digital Topology a new framework for digital topology has been proposed. This framework offers the possibility of transfering, in an easy way, definitions, statements and proofs from continuous topology to digital topology.

2D Covalent Moiré Superlattice from Fluorinating Twisted Bilayer Graphene
Advanced Functional Materials, Volume 35, Issue 16, April 18, 2025.A novel class of moiré materials, termed covalent moiré superlattice is proposed, which can be synthesized by functionalizing moiré van der Waals materials. By fluorinating twisted bilayer graphene, the weak van der Waals interactions between twisted graphene layers are transformed into strong covalent bonds, making the moiré superlattice effects ...
