Book Description
Silicon carbide (SiC) has been described as a suitable semiconductor material to use in MEMS and electronic devices for harsh environments. In recent years, many developments in SiC technology as bulk growth, materials processing, electronic devices and sensors have been shown. Moreover, some studies show the synthesis, characterisation and processing of crystalline SiC films. However, few works have investigated the potential of amorphous silicon carbide (a-SiC) thin films for sensors applications. This book presents fundamentals of amorphous silicon carbide thin films and their applications in piezoresistive sensors for high temperature applications.

Book Description
This volume contains written versions of the papers presented at the Second Inter national Conference on Amorphous and Crystalline Silicon Carbide and Related Materials (ICACSC 1988), which was held at Santa Clara University on Decem ber 15 and 16, 1988. The conference followed the First ICACSC held at Howard University, Washington DC, in December 1987 and continued to provide an in ternational forum for discussion and exchange of ideas and results covering the current status of research on SiC and related materials. ICACSC 1988 attracted 105 participants from five countries. The substantial increase in the number of papers compared with the previous year is an indication of the growing interest in this field. Of the 45 papers presented at the conference, 36 refereed manuscripts are included in this volume, while the remaining 9 appear as abstracts. The six invited papers provide detailed reviews of recent results on amorphous and crystalline silicon carbide materials and devices, as well as diamond thin films. The volume is divided into six parts, each covering an important theme of the conference.

Book Description
Silicon carbide and other group IV-IV materials in their amorphous, microcrystalline, and crystalline forms have a wide variety of applications.The contributions to this volume report recent developments and trends in the field. The purpose is to make available the current state of understanding of the materials and their potential applications. Eachcontribution focuses on a particular topic, such as preparation methods, characterization, and models explaining experimental findings. The volume also contains the latest results in the exciting field of SiGe/Si heterojunction bipolar transistors. The reader will find this book valuable as a reference source, an up-to-date and in-depth overview of this field, and, most importantly, as a window into the immense range of reading potential applications of silicon carbide. It is essential for scientists, engineers and students interested in electronic materials, high-speed heterojunction devices, and high-temperature optoelectronics.

Book Description
In this study, hydrogenated amorphous silicon carbide thin films were deposited by reactive ion-beam sputtering under varying conditions to determine whether a film's optical properties can be controlled, focusing on refractive index. Using a Kaufman type ion source to sputter a pure silicon target, three distinct series of films were grown. The first series varied the mixture of methane and argon used in the ion-beam. holding all other parameters constant. For the second series the gas mix was fixed, and only the beam energy (beam voltage) was varied. The final series also varied beam energy, but was grown with a graphite shield next to the target to reduce metal contamination sputtered from chamber surfaces. Results show the index of refraction increased monotonically with beam energy up to a beam voltage of 1300 volts. Both the second and third series of films followed this trend, but analysis of differences in atomic composition between two series revealed opposite trends for how the silicon to carbon content ratio and refractive index were related. More precise control of the gas flow, and sputtering from only the intended (silicon)target would have reduced experimental errors.

Book Description
This book on amorphous silicon technology shows a trend towards technologies based on amorphous and heterogeneous silicon (solar cells, TFTs, imaging arrays, sensors, etc.) and brings together researchers from around the world to share their expanding expertise. The book contains eleven chapters and focuses on basic mechanisms of growth (as well as new approaches to film growth); hot wire, CVD-produced amorphous and microcrystalline films and related subjects of film crystallization and recrystallization; the electronic structure and transport properties of silicon-based thin films are discussed, together with hydrogen microstructure and metastability. Silicon nitride, four on alloys with germanium, and two dealing predominantly with silicon carbide are looked at. There is also focus on photovoltaic devices based on either amorphous or microcrystalline (or mixed phase) materials. It also offers a look at thin-film transistors, as well as related types of imaging and sensing arrays and there are papers on novel device structures and new types of technologies being developed using amorphous/heterogeneous thin film, silicon-based materials.
