The ability to tailor the properties of silicon, by controlling its surface morphology in the form of black silicon, is anticipated to revolutionize silicon photonics. Black Silicon (BSi), one of the approaches to counter the inherent disadvantages of Si, is a surface modification of crystalline Si (c-Si). This book presents a discussion on manufacturing BSi by various methods for morphing the surface of the material, which are economical and easily applicable for mass production. Comparisons of the surfaces of BSi fabricated by various techniques are presented and thermal, electrical, electronic, and optical properties of black silicon are described. Some major applications of BSi have been given and possible future directions in the research and development of BSi and its applications are identified.

The book systematically accounts for the scientific and technological problems of nanostructured silicon in the form of porous and black silicon. Nanostructured silicon is currently a pioneer research topic worldwide due to its enormous potential applications for modern electronic devices, such as sensitive photodetectors, solar cells, biochemical sensors, hydrogen generators, and display devices. The main structural modifications of this nanomaterial are porous and black silicon. Porous silicon addresses crystalline silicon with nanopores and black silicon with nanoneedles. Historically, porous silicon is thought to be a kind of precursor to black silicon. The formation, research, and application of nanostructured silicon remains the main cornerstone of nanotechnologies, and this book is useful for a wide range of researchers in the fields of semiconductor physics, micro-, and nanoelectronics. The author outlines the prospect of black silicon fabrication and its various applications. As for porous silicon, the book contains a detailed analysis of this material as a precursor of black silicon. This allows it to be possible to carry out correlations between two structural modifications of nanostructured silicon to clearly and reasonably show their advantages and disadvantages. With many references to a vast resource of recently published literature, this book serves as an important and insightful source of valuable information and provides scientists and engineers with new ideas to better understand the formation processes of nanostructured silicon as well as improve and expand their properties.

Silicon is the preeminent solar cell material of the day because it is the first semiconductor that was learned to commercialize and continues to be the principal semiconducting material used in photovoltaic technology for the manufacture of solar cells. Silicon, an indirect band gap semiconducting material, has a reflectance of about 30% in the visible range of wavelengths. Standard Silicon solar cells are not entirely useful in the infrared spectrum region. In order to enhance the performance of Silicon solar cells, reflectance losses must be minimized and absorption must be maximized. In the solar cell industry, anti-reflection (AR) coating is used to suppress reflection losses. AR coatings are limited in use because they only reduce the reflectance for a narrow range of wavelengths and incident angle since their functionality is based on a quarter-wavelength coating. Surface texturing is a technique, by which the reflectivity is reduced. Black Silicon is a material with surface roughness in the micron scale. Black Silicon, when used instead of Crystalline Silicon, offers the possibility to increase the absorption of light in the visible and infrared range of wavelengths. Black Silicon has a very low reflectivity in the visible range of wavelengths. It exhibits high absorptance in the visible and infrared region. The main objective of this thesis is to study the various fabrication techniques used to form Black Silicon, present a comparative study of structural differences and analyze its optical properties by simulation and compare them with the simulated and experimental optical properties of Black Silicon and Crystalline Silicon.

SiOnyx has developed an enhanced thin film silicon photovoltaic device with improved efficiency. Thin film silicon solar cells suffer from low material absorption characteristics resulting in poor cell efficiencies. SiOnyx's approach leverages Black Silicon, an advanced material fabricated using ultrafast lasers. The laser treated films show dramatic enhancement in optical absorption with measured values in excess of 90% in the visible spectrum and well over 50% in the near infrared spectrum. Thin film Black Silicon solar cells demonstrate 25% higher current generation with almost no impact on open circuit voltage as compared with representative control samples. The initial prototypes demonstrated an improvement of nearly 2 percentage points in the suns Voc efficiency measurement. In addition we validated the capability to scale this processing technology to the throughputs (

This book presents the state-of-the art of one of the main concerns with microprocessors today, a phenomenon known as "dark silicon". Readers will learn how power constraints (both leakage and dynamic power) limit the extent to which large portions of a chip can be powered up at a given time, i.e. how much actual performance and functionality the microprocessor can provide. The authors describe their research toward the future of microprocessor development in the dark silicon era, covering a variety of important aspects of dark silicon-aware architectures including design, management, reliability, and test. Readers will benefit from specific recommendations for mitigating the dark silicon phenomenon, including energy-efficient, dedicated solutions and technologies to maximize the utilization and reliability of microprocessors.
