A construction of semi-infinite de Rham cohomology [PDF]

open access: yes
The purpose of this thesis is to describe a construction of semi-infinite de Rham cohomology for infinite dimensional manifolds equipped with the extra structure of a polarisation.

Fiber‐Endface‐Integrated PdSe2/2H‐MoTe2 Heterojunction Photodetector for Broadband Linear‐Polarization Detection

open access: yesAdvanced Materials Interfaces, EarlyView.
An all‐in‐fiber broadband polarization photodetector is demonstrated by integrating a PdSe2/2H‐MoTe2 van der Waals heterostructure onto a fiber endface. The device exhibits broadband response spanning 532 nm to 1630 nm, a fast response time of 59 µs, and a polarization ratio of 1.99. This work demonstrates a promising hardware strategy for polarization

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials

open access: yesAdvanced Materials Interfaces, EarlyView.
Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Linking Device Performance to Nanoscale Photoactivation of Grain Boundaries in 2D Hybrid Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
The opto‐electronic response of polycrystalline (PEA)2PbBr4 thin films is investigated by correlating macroscopic photodetector performance with nanoscale mapping techniques. Grain boundary density is systematically tuned through crystallization control and linked to device responsivity.
