Inorganic semiconducting materials for flexible and stretchable electronics
npj Flexible Electronics, 2017Co-Authors: Ki Jun Yu, Zheng Yan, Mengdi Han, John A RogersAbstract:Recent progress in the synthesis and deterministic assembly of advanced classes of single crystalline Inorganic Semiconductor nanomaterial establishes a foundation for high-performance electronics on bendable, and even elastomeric, substrates. The results allow for classes of systems with capabilities that cannot be reproduced using conventional wafer-based technologies. Specifically, electronic devices that rely on the unusual shapes/forms/constructs of such Semiconductors can offer mechanical properties, such as flexibility and stretchability, traditionally believed to be accessible only via comparatively low-performance organic materials, with superior operational features due to their excellent charge transport characteristics. Specifically, these approaches allow integration of high-performance electronic functionality onto various curvilinear shapes, with linear elastic mechanical responses to large strain deformations, of particular relevance in bio-integrated devices and bio-inspired designs. This review summarizes some recent progress in flexible electronics based on Inorganic Semiconductor nanomaterials, the key associated design strategies and examples of device components and modules with utility in biomedicine.

Inorganic Semiconductor nanomaterials for flexible and stretchable bio-integrated electronics
NPG Asia Materials, 2012Co-Authors: Dae-hyeong Kim, Roozbeh Ghaffari, John A RogersAbstract:Semiconductors are materials — traditionally Inorganic ones — that can act as either conductors or insulators under different conditions. They form the foundation of electronics and play a crucial role in many devices. John Rogers and co-workers discuss recent advances that have made possible the preparation of Inorganic Semiconductors as nanowires or nanomembranes, their assembly together with organic components into hybrid materials, and their integration into devices. These one- and two-dimensional structures allow for the construction of electronic or opto-electronic devices that are flexible and stretchable — properties that are particularly, albeit not exclusively, promising for biological applications. Systems capable of mapping the electrical activity of the heart and brain have been built, and assemblies whose characteristics mimic those of human skin have led to the construction of epidermal electronic devices. Such devices hold promise for monitoring functional activity and for therapeutic interventions.

synthesis optical properties and chemical biological sensing applications of one dimensional Inorganic Semiconductor nanowires
Progress in Materials Science, 2013Co-Authors: Chwee Teck LimAbstract:Abstract One-dimensional Inorganic Semiconductor nanowires form an attractive class of materials for different sensing applications as a result of their distinctive size- and shape-dependent physical properties. Numerous synthesis and characterization methods have been developed in recent years to realize high-quality Semiconductor nanowires with controllable dimensions, shape, and morphology. Additionally, a growing number of novel chemical and biological sensors with high sensitivity and selectivity have been developed based on Semiconductor nanowires. In this review, several main approaches in synthesizing Semiconductor nanowires, i.e., the vapor phase, solution phase, and template-based syntheses, are discussed. These include the vapor–liquid–solid (VLS), vapor–solid (VS), solution–liquid–solid (SLS), supercritical fluid–liquid–solid (SFLS), oriented attachment, and the hard and soft templates-assisted growth mechanisms. Next, the optical properties of these nanowires, in particular the UV–vis absorption, photoluminescence, and Raman properties, are explored. Recent advances in the chemical and biological sensing applications of Semiconductor nanowires are then presented. For instance, the applications of Semiconductor nanowires as NH3, H2, NO2, and other chemical and gas sensors as well as DNA, miRNA, glucose, uric acid, cysteine, and other biological sensors are briefly mentioned. Finally, this review summarizes and projects the future development of this field.

all Inorganic Semiconductor nanowire mesh for direct solar water splitting
ACS Nano, 2014Co-Authors: Bin Liu, Jianwei Miao, Peidong YangAbstract:The generation of chemical fuels via direct solar-to-fuel conversion from a fully integrated artificial photosynthetic system is an attractive approach for clean and sustainable energy, but so far there has yet to be a system that would have the acceptable efficiency, durability and can be manufactured at a reasonable cost. Here, we show that a Semiconductor mesh made from all Inorganic nanowires can achieve unassisted solar-driven, overall water-splitting without using any electron mediators. Free-standing nanowire mesh networks could be made in large scales using solution synthesis and vacuum filtration, making this approach attractive for low cost implementation.

Inorganic Semiconductor Nanowires: Rational Growth, Assembly, and Novel Properties
Chemistry - A European Journal, 2002Co-Authors: Haoquan Yan, Michael Huang, Benjamin Messer, Jae Hee Song, Peidong YangAbstract:Rationally controlled growth of Inorganic Semiconductor nanowires is important for their applica- tions in nanoscale electronics and photonics. In this article, we discuss the rational growth, physical proper- ties, and integration of nanowires based on the results from the authors× laboratory. The composition, diameter, growth position, and orientation of the nanowires are controlled based on the vapor ± solid ± liquid (VLS) crystal growth mechanism. The thermal stability and optical properties of these Semiconductor nanowires are investigated. Particularly, ZnO nanowires with well- defined end surfaces can function as room-temperature ultraviolet nanolasers. In addition, a novel microfluidic- assisted nanowire integration (MANI) process was de- veloped for the hierarchical assembly of nanowire build- ing blocks into functional devices and systems.

Inorganic Semiconductor Nanowires
International Journal of Nanoscience, 2002Co-Authors: Peidong Yang, Rong FanAbstract:One-dimensional (1D) nanostructures are ideal systems for investigating the dependence of electrical transport, optical properties and mechanical properties on size and dimensionality. They are expected to play an important role as both interconnects and functional components in the fabrication of nanoscale electronic and optoelectronic devices. This article presents an overview of current research activities that center on nanowires whose lateral dimensions fall anywhere in the range of 1–200 nm. It is organized into three parts: The first part discusses various methods that have been developed for generating nanowires with tightly controlled dimensions, orientations, and well-defined properties. The second part highlights a number of strategies that are being developed for the hierarchical assembly of nanowire building blocks.
