Emergent Berry Curvature in Inversion‐Symmetric Photonic Crystals for Ultraconfined Topological States

open access: yesAdvanced Materials, EarlyView.
In this work, nonzero Berry curvature in photonic crystals is induced by breaking unit cell inversion symmetry through spatial shifts rather than geometrical modifications. This enables the design of ultraconfined topological states with subwavelength in‐plane field confinement and out‐of‐plane field isolation.

HZO/HSO Superlattice ReFET Array Integrating Optical Sensing for Neuromorphic Vision Computing

open access: yesAdvanced Materials, EarlyView.
A photonic ReFET array with an engineered HZO–HSO superlattice enables monolithic integration of optical sensing, nonvolatile memory, and synaptic computation. It exhibits forming‐free, >8‐bit analog states, >1010 endurance cycles, and light‐tunable conductance.

High‐Resolution Mechanoluminescent Haptic Sensor via Dual‐Functional Chromatic Filtration by a Conjugated Polymer Shell

open access: yesAdvanced Materials, EarlyView.
A high‐resolution mechanoluminescence (ML) platform is achieved through chromatic filtration strategy using a conjugated polymer shell (F8BT) on copper‐doped zinc sulfide microparticles. This shell narrows the emission bandwidth, selectively filtering out blue noise, while simultaneously boosting intensity via ML photon recycling process.

Electrically‐Driven 2D Semiconductor Microcavity Laser

open access: yesAdvanced Materials, EarlyView.
The first electrically‐driven 2D semiconductor microcavity laser is achieved at room temperature under AC voltage driving conditions. The demonstration of the compact 2D TMDC laser establishes a new area of research to assist with the implementation of diverse 2D material‐based practical photonic devices and integrated circuits in the future.

Computation of Treespan. A Generalization of Bandwidth to Treelike Structures

open access: yes, 2012
Motivated by a search game, Fomin, Heggernes and Telle [Algorithmica, 2005] defined the graph parameter treespan, a generalization of the well studied parameter bandwidth. Treespan is the maximum number of appearances of a vertex in an ordered tree decomposition, i.e. a tree decomposition intro- ducing at most one new vertex in each bag. In this thesis,
