Nanophotonics has emerged as a major technology and applications domain, exploiting the interaction of light-emitting and light-sensing nanostructured materials. These devices are lightweight, highly efficient, low on power consumption, and are cost effective to produce. The authors of this book have been involved in pioneering work in manufacturing photonic devices from carbon nanotube (CNT) nanowires and provide a series of practical guidelines for their design and manufacture, using processes such as nano-robotic manipulation and assembly methods. They also introduce the design and operational principles of opto-electrical sensing devices at the nano scale. Thermal annealing and packaging processes are also covered, as key elements in a scalable manufacturing process. Examples of applications of different nanowire based photonic devices are presented. These include applications in the fields of electronics (e.g. FET, CNT Schotty diode) and solar energy. Discusses opto-electronic nanomaterials, characterization and properties from an engineering perspective, enabling the commercialization of key emerging technologies Provides scalable techniques for nanowire structure growth, manipulation and assembly (i.e. synthesis) Explores key application areas such as sensing, electronics and solar energy

Three aspects covering new material, long lasting energy and innovative heterojunction optoelectronics, which are graphene, betavoltaic microbatteries and group IV/III-V photodiodes, have been systematically studied in this thesis. By a first-principles study, we find that local strain with a proper range and strength along the zigzag direction results in opening of significant band gaps in graphene, with the maximum band gap of 1.0 eV; whereas, local strain along the armchair direction fails to open a band gap in graphene. There is a band gap opening in rippled graphene by a first-principles calculation. Generally, the value of the band gap increases as the amplitudes of ripples increase, while it decreases as the periodicities of ripples enlarge. The maximum band gap opened in rippled graphene can reach several hundred meV. To optimize the device design and improve the energy conversion efficiency of betavoltaic microbatteries, a comprehensive theoretical modeling and analysis have been performed. By employing the Monte Carlo method and Synopsys℗ʼ Medici device simulator, we investigate the performance of 4H-SiC p-n junction based betavoltaic microbatteries under exposure to a practical Ni-63 source with considering isotope impurities, self-absorption, and the full beta energy spectra. From simulating the effects of both the p-n junction configuration and the isotope source thickness on the battery performance, we propose that a p-n junction betavoltaic cell with a thicker and heavily doped p- layer under exposure to a practical Ni-63 source of a proper thickness could produce the optimal energy conversion efficiency up to 13% in 4H-SiC. Through the nanomembrane transfer-printing technique, we demonstrate the formation and characteristics of hetero p-n junction photodiodes formed between the single-crystal silicon nanomembrane (SiNM) or germanium nanomembrane (GeNM) and the gallium arsenide (GaAs) substrate. Excellent rectifying characteristics are obtained from both types of heterogeneous p-n photodiodes. The SiNM/GaAs photodiode exhibits photosensitivity at visible wavelengths with a photo-to-dark current ratio exceeding five orders and an external quantum efficiency of 29.6% at 633 nm of wavelength. For the GeNM/GaAs photodiode, a photo-to-dark current ratio exceeds six orders and an external quantum efficiency of 22.3% at 633 nm is observed.

Beginning with an introduction to carbon-based nanomaterials, their electronic properties, and general concepts in quantum transport, this detailed primer describes the most effective theoretical and computational methods and tools for simulating the electronic structure and transport properties of graphene-based systems. Transport concepts are clearly presented through simple models, enabling comparison with analytical treatments, and multiscale quantum transport methodologies are introduced and developed in a straightforward way, demonstrating a range of methods for tackling the modelling of defects and impurities in more complex graphene-based materials. The authors also discuss the practical applications of this revolutionary nanomaterial, contemporary challenges in theory and simulation, and long-term perspectives. Containing numerous problems for solution, real-life examples of current research, and accompanied online by further exercises, solutions and computational codes, this is the perfect introductory resource for graduate students and researchers in nanoscience and nanotechnology, condensed matter physics, materials science and nanoelectronics.
