Nonreciprocal Microwave Transmission in a Passive-Active Double-Cavity-Magnon System

open access: yesIEEE Photonics Journal
We propose a scheme to realize nonreciprocal microwave transmission in a double-cavity-magnon system, which comprises a ferromagnetic yttrium iron garnet (YIG) sphere placed inside a passive microwave cavity coupled to another active cavity.

Definition differences and internal variability affect the simulated Arctic sea ice melt season [PDF]

open access: yesThe Cryosphere, 2019
Satellite observations show that the Arctic sea ice melt season is getting longer. This lengthening has important implications for the Arctic Ocean's radiation budget, marine ecology and accessibility.

Extremely Long Electron Lifetime in Spontaneously Passivated Polycrystalline Perovskite Layers via Illumination‐Assisted Trap Filling

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT Perovskite solar cells (PSCs) are promising next‐generation photovoltaics. The high performance of PSCs is attributed to the long carrier lifetimes of perovskite photoabsorbers. However, the carrier lifetimes of polycrystalline perovskite layers, which serve as the photoabsorbers in practical PSCs, have remained limited to several tens of ...
