1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The intrinsic planarity of two-dimensional (2D) van der Waals (vdW) polaritonic media inherently limits the lateral confinement of vdW polaritons. Here, we transcend this geometric limit by introducing a deterministic strategy to engineer non-planar nano-wrinkle waveguides in hexagonal boron nitride (hBN) via controlled thermal buckling. By exploiting the thermal expansion features of a calcite substrate, we generate uniaxial stress during cooling, which naturally forms high-curvature wrinkles in the overlying hBN superstrate. These wrinkles function as reconfigurable channel waveguides, guiding polaritons along predefined paths, and nano-hole patterning of such heterostructures offers programmable routing. Cryogenic near-field imaging and simulations reveal a wrinkle-guided polariton mode with a wavevector and dispersion governed by the wrinkle geometry and distinct from substrate-supported branches. Their hybridization allows precise tuning of modal confinement via hBN thickness variation. Concurrently, these structures guide polariton-mediated heat flow, establishing a medium-free mechanism for nanoscale thermal management. More broadly, our approach establishes a universal route for the geometric control of light and heat in two-dimensional materials.
