Mixed‐Polymer Hole Transport Layers Reinforce Au‐Anode Top Emitting Perovskite Light Emitting Diodes
Advanced Science, EarlyView.Au‐anode corrosion is shown to occur rapidly under voltage bias in MAPbI3 perovskite LEDs. Resulting Au+ migration quickly leads to device shorting and unstable emission during constant current driving. We demonstrate that using a simple mixed‐polymer hole transport layer containing polyTPD and PVK can reduce Au‐corrosion and stabilize LED operation ...

Microcavity-Mediated Spectrally Tunable Amplification of Absorption in Plasmonic Nanoantennas
, 2019 Nanoantenna–microcavity hybrid systems offer unique platforms for the study and manipulation of light at the nanoscale, since their constituents have either low mode volume or long photon storage time.

Advanced Science, EarlyView.PDGFA/PDGFRα signaling recruits CAFs to OSCC nests, and CAF‐OSCC contact drives tumor budding invasion. Mechanistically, heterotypic adhesion via E‐cadherin/integrin α2β1 activates YAP signaling in OSCC cells, inducing EMT. Concurrently, CAFs transfer mitochondria through TNTs, supplying ATP to fuel invasion.

Microcavity-enhanced Kerr nonlinearity in a vertical-external-cavity surface-emitting laser
, 2018 Self-mode-locking has become an emerging path to the generation of ultrashort pulses with vertical-external-cavity surface-emitting lasers. In our work, a strong Kerr nonlinearity that is so far assumed to give rise to mode-locked operation is evidenced ...

Patterns in Broad-Area Microcavities [PDF]
physica status solidi (b), 2000 The emergence of spatial structures with an approximate hexagonal symmetry is observed in broad area amplifying microcavities with injection of a homogeneous beam. The length scale is controllable via detuning. Optical bistability occurs close to the longitudinal resonance.

Exceptional points of third-order in a layered optical microdisk cavity
New Journal of Physics, 2018 A striking signature of the non-Hermitian physics in open systems is the existence of exceptional points (EPs) in parameter space. In contrast to a conventional degeneracy, an EP involves not only the coalescence of the eigenvalues but simultaneously ...
