Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

Advanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

Shortest Path Problem by Minimal Spanning Tree Algorithm using Bipolar Neutrosophic Numbers

, 2017
Normally, Minimal Spanning Tree algorithm is used to nd the shortest route in a network. Neutrosophic set theory is used when incomplete, inconsistancy and indeterminacy occurs.

Self‐Poled Halide Perovskite Ruddlesden‐Popper Ferroelectric‐Photovoltaic Semiconductor Thin Films and Their Energy Harvesting Properties

Advanced Functional Materials, EarlyView.
Low‐dimensional halide perovskite thin films, (BA)2(MA)n‐1PbnBr3n+1 (n = 1, 2), exhibit both semiconducting and ferroelectric properties, enabling mechanical and light energy harvesting. Using Cr/Cr₂O₃ or PCBM as barrier layers ensures reproducible ferroelectricity.

A new tool for exploring climate change induced range shifts of conifer species in China.

PLoS ONE, 2014
It is inevitable that tree species will undergo considerable range shifts in response to anthropogenic induced climate change, even in the near future. Species Distribution Models (SDMs) are valuable tools in exploring general temporal trends and spatial

High‐Entropy Magnetism of Murunskite

Advanced Functional Materials, EarlyView.
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

The prevalence of terraced treescapes in analyses of phylogenetic data sets

BMC Evolutionary Biology, 2018
Background The pattern of data availability in a phylogenetic data set may lead to the formation of terraces, collections of equally optimal trees. Terraces can arise in tree space if trees are scored with parsimony or with partitioned, edge-unlinked ...

Which Chromium–Sulfur Compounds Exist as 2D Material?

Advanced Functional Materials, EarlyView.
2D chromium sulfides synthesized using molecular beam epitaxy on graphene. Structural characterization reveals two novel 2D materials, Cr2S3‐2D, which lacks a direct bulk counterpart, and Cr223S${\rm Cr}_{2\frac{2}{3}}{\rm S}$4‐2D, a minimum thickness version of Cr5S6. However, attempts to synthesize CrS2 are unsuccessful. Both new 2D phases are stable

The Minimum Spanning Tree Problem on networks with Neutrosophic numbers [PDF]

Neutrosophic Sets and Systems
The minimum spanning tree problem (MSTP) revolves around creating a spanning tree (ST) within a graph/network that incurs the least cost compared to all other potential STs.

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...
