Saddle-like topological surface states on the TT'X family of compounds (T, T' = Transition metal, X= Si, Ge)

, 2017
Topological nodal-line semimetals are exotic conductors that host symmetry-protected conducting nodal-lines in their bulk electronic spectrum and nontrivial drumhead states on the surface.

Surface States of Topological Insulators [PDF]

, 2012
We develop an effective bulk model with a topological boundary condition to study the surface states of topological insulators. We find that the Dirac point energy, the band curvature and the spin texture of surface states are crystal face-dependent. For

Crystallization and particle size distribution of hydrothermally synthesized SAPO-34: an experimental and population balance study

Scientific Reports
A population balance-based model was developed to describe the crystallization kinetics of the SAPO-34 zeotype through the hydrothermal method at three distinct temperatures of 180, 200, and 220 °C. The synthesized SAPO-34 catalysts were characterized by

Dual Passivation of Perovskite and SnO2 for High‐Efficiency MAPbI3 Perovskite Solar Cells

Advanced Science, 2021
So far, most techniques for modifying perovskite solar cells (PSCs) focus on either the perovskite or electron transport layer (ETL). For the sake of comprehensively improving device performance, a dual‐functional method of simultaneously passivating ...

Integrated Logic Circuits Based on Wafer-Scale 2D-MoS₂ FETs Using Buried-Gate Structures

Nanomaterials, 2023
Two-dimensional (2D) transition-metal dichalcogenides (TMDs) materials, such as molybdenum disulfide (MoS2), stand out due to their atomically thin layered structure and exceptional electrical properties.

On the energy-momentum tensor for a scalar field on manifolds with boundaries

, 2003
We argue that already at classical level the energy-momentum tensor for a scalar field on manifolds with boundaries in addition to the bulk part contains a contribution located on the boundary. Using the standard variational procedure for the action with

New insights into the properties of pubescent surfaces: peach fruit as model [PDF]

, 2011
The surface of peach (Prunus persica ‘Calrico’) is covered by a dense indumentum, which may serve various protective purposes. With the aim of relating structure to function, the chemical composition, morphology, and hydrophobicity of the peach skin was ...
