PREFACE

PREFACE  
 
The advent of nanotechnology is becoming an ever-visible concept in various aspects of our lives, as evident by its popular (and often incorrect) usage in advertising/marketing and enter-tainment. Although pop-culture references to nanotechnology are often misused or are total science fiction, its origins are derived from a rapidly growing discipline of science and engi-neering. Nanotechnology can be defined as the fundamental study and application of materials displaying length scales of more than 100 nm. At this size, nanoscale materials exhibit physical and chemical properties that differ greatly from those of their bulk counterparts. These interesting properties can be advantageously exploited for a number of applications and have substantial real-world impacts in fields such as medicine and those that are energy-related. Although nanotechnology research is growing rapidly throughout the world, the teaching of this subject is lacking at the university level, particularly at the first-year and second-year levels. Introducing nanotech-nology earlier during the college curriculum would be of immense benefit to students and to further progress in the field. As such, the motivation in preparing this book is to introduce the concept of nanotechnology in teaching while exposing students to current nanotechnology research. Given the ever-changing nature of nanotechnology, researchers in the field need to be constantly aware of new studies to update their knowledge and to keep current. With the advent of the Internet, research data and ideas are now readily accessible and commu-nicated to the rest of the field and serve as a plentiful source for newcomers looking to learn more about this exciting field. This can be a double-edged sword, however, because the sheer amount of information can be difficult to organize and process. Furthermore, the Internet is a nonrefereed medium and, as such, information needs to be taken with a critical viewpoint. From an educational standpoint, a major challenge is teaching students how to recognize and collect useful online resources while simultaneously instilling an intuition in the students about potentially less credible or incorrect online resources. Motivated by the facts stated here, the author felt the need for a new perspective on the progress of nanotechnology research.  
Nanomaterials and related nanoscale devices constitute the core infrastructure of nanoscience and technology. With the  
vi PREFACE  
development of nanomaterials synthesis and characterization techniques, the fundamental knowledge base has grown consid-erably, resulting in a thorough understanding of nanoscale properties that can be used to develop novel devices in various application areas. To this end, the major focus of this book is nanomaterials and devices. We hope this textbook will become a useful tool for students to bridge their acquired knowledge to their current or future research activities, because a major aim of this text is to prompt research into practical applications. This book references knowledge from three areas: the author’s own research activities, the selected literature, and Internet resources. Regarding content selected from online resources, we have performed extensive background studies to verify that the information is correct. Additionally, we also have cited direct references to a few online resources without the original source being indicated in the reference, and for that we must apologize here and acknowledge the original authors. Our thanks are hereby extended to all the original authors who may be involved in the contents herein.  
It is our desire to publish this textbook for many years to come, updating future versions with the newest trends in nano-technology research. We thank Tsinghua University Press for their support throughout the process of writing this book.  
Given the targeted readership level, the short period of prep-aration, and the inherent diversity within the field of nanotech-nology, there may be shortcomings that are inevitable in the book. All colleagues and readers are encouraged to kindly con-tact the authors with your professional opinions and sugges-tions for new material.

　　For instance, Moore's law isbeginning to face serious challenges. The SET is likely to be anew generation of electronic devices in the mainstream of thetwenty-first century.
　　3.4.1.3 CNT Electronics [7-9]
　　Diodes, FETs, and other elements of electronic devices formthe basis of silicon-based microelectronics. Similarly, the development of nanoelectronics requires a new materials frameworkto be built, whereas the field of CNT-based electronics has beenconsidered to be very promising.
　　The development of CNT electronics will mainly comethrough the following stages. First, the electrical properties ofCNTs must be fully elucidated. Second, the base elementsof CNT-based electronic devices need to be identified anddeveloped (that is, those elements corresponding to siliconbased microelectronics, such as diodes and FETs). Third, theseelectronic devices based on CNTs are used to build a logic circuit with certain functions. Finally, the key issue to be resolvedis how to achieve the integration of these circuits reliably on amass-production scale. At present, CNT electronics researchhas made great progress in the first two stages. Meanwhile, thethird stage of the research work is underway. There are reportsthat prototype CNT-based logic circuits have been built inlaboratories.
　　3.4.1.3.1 Quantum Wire
　　The study of quantum wires mainly concentrates on a variety of CNTs. CNTs are the ideal material for quantum wires.Quantum wire made from CNTs is called nanotube quantumwire. Currently, the conductivity of such large molecules isbeing extensively studied.
　　Different CNTs can be candidates in the formation of a variety of nonlinear electronic devices. The chirality of CNTs can beused to determine whether these CNTs have the features ofbeing a conductor or a semiconductor. Furthermore, differentlocal defects, such as the existence of five-membered rings and/or six-membered rings, may affect their electronic properties.
