Abstract
In this study, we explore the effects of introducing random impurities into zigzag bismuth nanoribbons on their edge states and thermoelectric properties. Bismuth nanoribbons with zigzag edges are known for their unique electronic properties, particularly the presence of robust edge states that significantly influence their thermoelectric performance. By strategically incorporating random impurities into the nanoribbons, we aim to manipulate and separate these edge states, thereby enhancing the overall thermoelectric efficiency. Our results demonstrate that the introduction of impurities effectively decouples the edge states from the bulk states, leading to a clear enhancement in thermoelectric properties. This indicates the potential of this method for developing advanced thermoelectric materials. This approach opens new avenues for the design of high-performance thermoelectric devices through impurity engineering in low-dimensional materials.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
