Complementary methodologies for thin film characterization in one tool - a novel instrument for 450 mm wafers [PDF]

, 2013
The scaling down of critical dimensions for the manufacturing of nanoelectronics requires the continuous introduction of new materials. The results of the analysis of thin high-k films made from Al2O3 as reference samples were used at multiple ...

Ultrathin Quasi‐2D Perovskite‐Organic Segregated‐Structure Coupling for High‐Performance Narrowband Photomultiplication Detectors

Advanced Science, EarlyView.
Quasi‐2D perovskite‐organic segregated‐structure coupling enables low‐power narrowband photomultiplication photodetectors with 110 nm perovskite layer. The optimal device achieves 1200% EQE and 1.82 × 1011 Jones D* at 3 V, offering a new strategy for miniaturized high‐selectivity optoelectronic sensing.

Ordered arrays of metal nanostructures on insulator/metal film: dependence of plasmonic properties on lattice orientation

Nano Express
We study the dependence of the optical response of square lattices of plasmonic nanoparticles on the mutual orientation of the lattice and the plane of incidence of illuminating light.

Ellipsometry of human tears [PDF]

The Ocular Surface, 2019
The outer surface layer of tears is presumably composed of lipid. The thickness of this layer is considered critical to retard evaporation. Prior thickness measurements differ widely. Advances in ellipsometry have availed more precise and accurate measurements for thin films.

Ultrabroadband and Highly Sensitive Short‐Wave Infrared Molecular Fingerprinting via Acoustic MXene Plasmons

Advanced Science, EarlyView.
Acoustic plasmons in Ti3C2Tx MXene strongly compress infrared electromagnetic fields and enhance light–matter interactions at the nanoscale. This platform couples broadband plasmon excitations with molecular vibrations, enabling simultaneous sensing of high‐ and low‐frequency vibrational modes in ultrathin PMMA and graphene oxide films, and extending ...

A Dual‐Channel Synergistic Ultrasensitive Biosensor for Tumor Liquid Biopsy

Advanced Science, EarlyView.
ABSTRACT Liquid biopsy technology, which detects circulating tumor DNA (ctDNA) in cerebrospinal fluid, plays a crucial role in the early diagnosis and precision treatment of gliomas. However, the intrinsically low abundance and rapid clearance of ctDNA pose substantial challenges for conventional analytical techniques, such as droplet digital PCR and ...

Sticky Yet Slippery: Molecular Ordering Reconciles Bubble‐Surface Affinity With Ultralow Friction at the Nanoscale

Advanced Science, EarlyView.
By engineering the molecular order and thickness of PDMS layers, we reconcile the stickiness and slipperiness during bubble transport. AFM measurements and MD simulations further reveal how these nanoscale architectures tune hydrophobic interaction FHB and friction force f.
