Magnetoelectric BaTiO3/CoFe2O4 Thin‐Film Meshes for Neuronal Differentiation

Advanced Science, EarlyView.
We engineer an epitaxial BaTiO3/CoFe2O4 magnetoelectric mesh that overcomes boundary‐induced mechanical clamping. Progressively reducing the mechanical constraint, from substrate‐clamped to PDMS‐transferred and ultimately freestanding, enhances magnetic‐to‐electric transduction and strengthens magnetoelectric coupling.

Light‐Absorbing‐Layer‐Free Flash Lamp Annealing for High‐Throughput Fabrication of All‐Solution‐Processed Oxide Electronics

Advanced Science, EarlyView.
A flash lamp annealing strategy using a mullite chuck enables rapid conversion of sol–gels to metal oxides on silicon and ultra‐thin glass without extra light‐absorbing layers. Direct light absorption initiates the transformation, and the low thermal conductivity of mullite promotes heat accumulation.

Multi‐Vth IGZO FETs Enabled by Continuous‐wave Laser Scanning Annealing for Low Thermal Budget 3D Integration

Advanced Electronic Materials, EarlyView.
A novel strategy is used to fabricate multi‐threshold‐voltage (multi‐Vth) IGZO FETs via continuous‐wave laser scanning annealing (CW‐LSA). By tuning the laser power and scan speed, low, standard, and high Vth values of 0.22, 0.42, and 0.62 V, respectively, were achieved on a single wafer with excellent uniformity (coefficient of variation: 2.17%–6.61%).

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

Advanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Inscription and Thermal Stability of Fiber Bragg Gratings in Hydrogen-Loaded Optical Fibers Using a 266 nm Pulsed Laser

Photonics
Fiber Bragg gratings (FBGs) have gained substantial research interest due to their exceptional sensing capabilities. Traditionally, FBG fabrication has required the use of pre-hydrogenated fibers and high-cost laser systems such as excimer lasers at 193 ...

Exploiting Temperature Effects for Robust Control and Reference Circuits Using Thin‐Film Contact‐Controlled Transistors

Advanced Electronic Materials, EarlyView.
Compact circuits based on contact‐controlled transistors are well‐suited to unsupervised thermal management, sensitive temperature measurement, or temperature‐stable current references. Demonstrated on flexible microcrystalline silicon and supported by simulation, the approach does not require supply voltage regulation, remains manufacturable across ...

Excimer Lasers

SPIE Proceedings, 1987
A review of excimer laser systems is presented, including basic physical data, technology, performances and applications. The last few years have seen a rapid development of this new type of gas lasers and of many commercial systems producing efficient high power pulses of ultra-violet radiation.

Scan‐Path‐ and Initial‐State‐Dependent Superdomain Switching in (111)‐Oriented PZT

Advanced Electronic Materials, EarlyView.
Scan trajectory and initial superdomain topology govern polarization switching in (111)‐oriented PZT. Automated AFM writing, pulsing experiments, and interferometric 3D‐PFM show that raster scans reproducibly stabilize ordered Type‐I stripe superdomains with constrained variant selection, whereas spiral trajectories generate frustrated mixed‐variant ...
