Multiresonator-Based Printable Chipless RFID for Relative Humidity Sensing

Proceedings, 2017
We present a chipless RFID for relative humidity sensing. It consists of three spiral resonators coupled to a 50 Ω microstrip line. One resonator is used for humidity sensing, and the other two are used for encoding ID.

Low‐Loss Far‐Infrared Surface Phonon Polaritons in Suspended SrTiO3 Nanomembranes

Advanced Functional Materials, EarlyView.
The low‐loss, highly confined, and thickness‐tunable surface phonon polaritons are demonstrated in the far‐infrared regime within transferable freestanding SrTiO3 membranes, achieving high figures of merit comparable to the previous record values from the vdW materials.

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

Advanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Tailoring the Microstructure of B‐Cation Octahedra in Halide Double Perovskites for Efficient Selective CO2‐to‐CO Photoreduction

Advanced Functional Materials, EarlyView.
The thermodynamic obstacle of CO2‐to‐CO conversion over metal halide perovskite photocatalysts is addressed by modulating the local electronic structure. A 13‐fold improvement in selective CO2 photoreduction to CO is achieved, with ≈100% selectivity.

Formation of 2D Electron Gas at a Non‐Polar Perovskite Oxide Interface: SrHfO3/BaSnO3

Advanced Functional Materials, EarlyView.
Through experiments and Poisson‐Schrödinger simulations, 2D electron gas formed at the non‐polar SrHfO3/BaSnO3 interface is observed. A large conduction band offset enables modulation doping by the intrinsic deep donors in SrHfO3, resulting in carrier confinement in BaSnO3 without relying on interfacial polarization or termination‐layer engineering ...
