Hybrid Ferroelectric Tunnel Junctions with Intrinsic Nonlinearity and Self‐Rectification via Interfacial Reconstruction

Advanced Functional Materials, EarlyView.
Rapid thermal annealing reconstructs the BCFO/Nb:STO interface into an atomically thin reconstructed interfacial layer, which reshapes the tunneling barrier and converts a high‐TER ferroelectric tunnel junction into an intrinsically nonlinear, self‐rectifying device.

Carrier lifetime modulation on current capability of SiC PiN diodes in a pulsed system

Discover Nano, 2023
Silicon carbide (SiC) PiN diode has shown substantial promise as the freewheel diode for switch protection in a pulsed system. In this paper, we investigate the carrier lifetime (τ) modulation on pulsed current capability of SiC PiN diodes.

PIN Silicon Diodes as EXAFS Signal Detectors

Journal of Synchrotron Radiation, 1996
The properties of PIN silicon diodes as X-ray detectors for EXAFS measurements with synchrotron radiation have been investigated. Electronic stability, linearity and noise current have been analyzed. The effects of diffraction peaks resulting from the crystalline nature of the diodes have been minimized by mounting the diodes on a simple device that ...

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

Advanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Performance analysis of a tunable absorber based on active frequency selective surface

Zhongguo Jianchuan Yanjiu, 2020
Objectives A periodic absorber can absorb incident electromagnetic waves and effectively reduce the reflectivity of a target. To this end, a novel microwave absorber based on an active frequency selective surface (AFSS) is proposed in this paper.

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.
