Anisotropic Dopant and Strain Architectures in WS Nanocrystals Driven by Growth Kinetics
Frederico B. Sousa, Raphaela de Oliveira, Matheus J. S. Matos +11
Dopant distribution in two-dimensional semiconductors is typically assumed to be stochastic, limiting deterministic defect engineering. Here, we show that non-equilibrium growth ki…
Stacking-Tunable Electronic Properties in Recently Synthesized Hydrogen-Substituted Graphdiyne
Guilherme S. L. Fabris, Raphael B. de Oliveira, Bruno Ipaves +2
Recent progress in porous carbon materials has highlighted the importance of structural design in controlling emergent physicochemical properties. In this context, hydrogen-substit…
Alignment behavior of 2D diopsides (d-silicates) under the influence of an AC electric field
Himakshi Mishra, Surbhi Slathia, Bruno Ipaves +8
Controlling the alignment of two dimensional (2D) materials is crucial for optimizing their electronic and mechanical properties in next generation devices. This study explores how…
Novel 3D Pentagraphene Allotropes: Stability, Electronic, Mechanical, and Optical Properties
I. M. Félix, B. Ipaves, R. B. de Oliveira +5
Carbon-based materials have attracted great attention due to their exceptional structural diversity and wide-ranging applications. Recently, a new two-dimensional carbon allotrope,…
Nanoscale mechanics and ultralow Friction of natural 2D silicates: Biotite and Rhodonite
Surbhi Slathia, Manoj Tripathi, Raphael Benjamim de Oliveira +12
Two-dimensional (2D) silicates have emerged as a promising class of ultrathin materials, expanding the landscape of 2D systems beyond conventional van der Waals crystals. Their uni…
Nano-size fragmentation of Tantalum in Copper composite using additive manufacturing
Rakesh Das, Pawan Kumar Dubey, Raphael Benjamim de Oliveira +8
The biggest challenge in manufacturing an immiscible system is phase segregation and non-uniformity inside the composite matrix. Additive manufacturing has the potential to overcom…
