Label‐Free Super‐Resolution Imaging Using Non‐Linear Exogenous Photon Avalanche Backlight

Advanced Science, EarlyView.
Transmission avalanche backlight (TAB) microscopy turns a photon‐avalanching Tm3+:LiYF4 crystal into a nonlinear luminescent backlight. Weak attenuation by a transparent sample is amplified into strong emission modulation: image contrast increases with sample attenuation and avalanche nonlinearity (N), while the effective point spread function narrows ...

Broadband Back-Short Transition From Waveguide to Thin Substrate-Integrated Waveguide in Multilayer Substrate in 270-GHz Band

IEEE Journal of Microwaves
A broadband right-angle transition from a rectangular waveguide (RWG) to a substrate-integrated waveguide (SIW) with a small narrow-wall width is proposed in the 270 GHz band.

Robust NbN‐on‐Si/SiGe Hybrid Microwave Quantum Circuits With Long‐Term Stability

Advanced Electronic Materials, EarlyView.
Superconducting NbN resonators integrated with Si/SiGe quantum wells based semiconducting chip are investigated as a CMOS–compatible platform for scalable quantum hardware. Temperature–dependent microwave spectroscopy reveals loss mechanisms from TLS, quasiparticles, and scattering.

Millimetre wave wideband low-loss waveguide-to-substrate integrated waveguide transition

, 2017
A wideband Ka-band waveguide-to-substrate integrated waveguide transition is presented based on a multi-section transformer approach. We designed our transition by successfully adapting multi-section inhomogeneous waveguide transformer theory to match a ...

Beyond Charge: Field‐Effect Transistors in Multimodal Biosensing Platforms for Biomolecular Interaction Studies

Advanced Electronic Materials, EarlyView.
This review summarizes the developments in field‐effect transistor (FET)‐based dual‐mode sensor platforms and what can be learned from them. It identifies charge as a crucial factor in biomolecular interactions at interfaces, outlines the challenges of hybrid systems, and highlights their benefits.
