Abnormal Seebeck Effect in Vertically Stacked 2D/2D PtSe2/PtSe2 Homostructure

Advanced Science, 2022
When a thermoelectric (TE) material is deposited with a secondary TE material, the total Seebeck coefficient of the stacked layer is generally represented by a parallel conductor model.

Alternatingly Stacked Low‐ and High‐Resistance PtSe2/PtSe2 Homostructures Boost Thermoelectric Power Factors

Advanced Electronic Materials, 2023
2D transition‐metal dichalcogenide (TMDC) materials are promising candidates with excellent thermoelectric (TE) properties owing to their low dimensionality in electronic and phonon transport. However, the considerable coupling of the Seebeck coefficient

Differential Geometry of the Family of Helical Hypersurfaces with a Light-like Axis in Minkowski Spacetime ${\mathbb{L}}^4$

Universe, 2023
We investigate the class of helical hypersurfaces parametrized by x=x(u,v,w), characterized by a light-like axis in Minkowski spacetime L4. We determine the matrices that represent the fundamental forms, Gauss map, and shape operator of x.

Emergent Differential Organization of Airway Smooth Muscle Cells on Concave and Convex Tubular Surface

Frontiers in Molecular Biosciences, 2021
Airway smooth muscle cells (ASMCs) exist in a form of helical winding bundles within the bronchial airway wall. Such tubular tissue provides cells with considerable curvature as a physical constraint, which is widely thought as an important determinant ...
