An Efficient Computational Model for Metal Nanowire Transparent Conductors

获奖作品摘要

Transparent conductors are a class of materials widely needed for technologies such as smart phones and solar panels. The current industry standard, Indium Tin Oxide, is expensive, brittle, and in short supply. In this research, an alternative transparent conductor based on random metal nanowire networks was investigated. The specific objective of this work was to develop a versatile and efficient computational model capable of calculating the conductivity of such networks. Because the properties of this type of network depend on many independent parameters, such a model is a valuable tool for researchers looking to optimize conductivity. This computational model was validated through comparison with published experimental data. A power law relation between normalized conductivity and normalized wire concentration was determined, with an exponent of 1.73. Furthermore, the computational model was used to identify a novel method through which conductivity of the networks can be optimized: nanowire orientation. It was found that with an appropriate orientation distribution, a significant increase in conductivity can be achieved. Such advances will enable wider adoption of metal nanowire transparent conductors in industry.

学科简介：材料科学 Materials Science

The study of the integration of various materials forms in systems, devices, and components that rely on their unique and specific properties. It involves their synthesis and processing in the form of nanoparticles, nanofibers, and nanolayered structures, to coatings and laminates, to bulk monolithic, single-/poly-crystalline, glassy, soft/hard solid, composite, and cellular structures. It also involves measurements of various properties and characterization of the structure across length scales, in addition to multi-scale modeling and computations for process-structure and structure-property correlations.

Subcategories:

Biomaterials (BIM): Studies involving any matter, surface, or construct that interacts with biological systems. Such materials are often used and/or adapted for a medical application, and thus comprise whole or part of a living structure or biomedical device which performs, augments, or replaces a natural function.

Ceramic and Glasses (CER): Studies involving materials composed of ceramic and glass – often defined as all solid materials except metals and their alloys that are made by the high-temperature processing of inorganic raw materials.

Composite Materials (CMP): Studies that integrate multiple materials such as ceramics, fiber, metals or polymers to create a superior and unique material.

Computation and Theory (COM): Studies that develop and apply theoretical methods and/or use computer modeling to design new materials, predict material behavior under differing environmental conditions, understand energy transfer, etc.

Electronic, Optical and Magnetic Materials (ELE): The study and development of materials used to form highly complex systems, such as integrated electronic circuits, optoelectronic devices, and magnetic and optical mass storage media. The various materials, with precisely controlled properties, perform numerous functions, including the acquisition, processing, transmission, storage, and display of information.

Nanomaterials (NAN): The study and development of nanoscale materials; materials with structural features (particle size or grain size, for example) of at least one dimension in the range 1-100 nm.

Polymers (POL): The study and development of polymers; materials that have a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins.

Other (OTH): Studies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.
