Objection:
This course introduces fundamental knowledges on nanoscience and nanotechnology for Ph.D. candidates. They will be supposed to have a preliminary understanding of following topics included: manipulation of atom and the molecular, construction of object surface, nanometer processing, nanomeasurement, nanomaterial, nanoelectronics, nanomachinery, nanosensor, nanobiology, nanometer size effect, surface and the interface effect, single electron device and so on.
Description:
Due to the progress of observation and experimental method that the natural science and technology relies on, the nanometer criterion science and technology has made the unprecedented progress, and formed a developing and strongest significant interdisciplinary fields ---nanoscience and nanotechnology. It looks as growth spot for high tech and the important breakthrough and the present development in the information, biology, electron, chemical industry, agriculture, the military field and so on. Technology and the principle of nanometer criterion structure and object to observe and manipulate. Using of special phenomenon and the rules as well as the material special performance in nanometer criterion,
Object and the surface can be manipulated, transferred and constructed on atomic and molecular operation level. Therefore, a key nanometer dimension for modern science and higher-level technology can be relatively achieved.
This course presents an introduction to the principles of creating nanostructures and their applications in many fields. It provides an introduction to the physical concepts, techniques and applications of nanomaterials and nanodevices, covers the latest breakthrough of nanoscale systems right up to single-electron and molecular electronics. Nanomaterial, the active topic in nanoscience and nanotechnology, will be extensively studied . Nanomaterial , with the size smaller than 100 nanometer, has unique performance mainly displays in the size effect and the surface and the interfacial effect. The great progress in the study of the nanometer material has offered the possibility for nanoelectronics, nanomechanics and nanomanufacture. The devices with nano dimension in main body structure behave extremely low power loss, the high-density integration characteristic, and transport confinement of electronic in dimension size and electron coulomb block below the corresponding characteristic temperature. The single electronic device functions as the quantum effect control. The new nanoprocess technology will be the only way for ultra large-scale integrated circuit (VLSI) and high frequency electronic component. Currently, the research on fabricating nanodevices composed of the 0 and 1-D nanomaterials is great. The principally developing direction of nanoscience and nanotechnology will be nanodevices fabricated by nanosemiconducting materials combined with new processing technology compatible with an existing micro electron technology.
In conclusion, we can learn to use these unfamiliar principles to create valuable new materials and artefacts which will have a profound effect on medicine, electronics, energy and the environment in the next century. With a firmer understanding of the likely relationship between nanotechnology and nature itself, we can gain a much clearer notion of potential dangers posed by this powerful technology.
