| Nanodevices: Construction and Basic Study |
| 2009-09-14 |
Nanoscience and related technology are internationally recognized as one of the most important and most active fields in science & technology in the new century. Their development should have far-reaching impacts on every aspect of human society. Just as micro-electronic elements and devices used to be the hallmark of the era of micro-electronics, the mainstream in the era of nanoscience should be the development of nanostructural elements and nanodevices. The study of nanodevices has been listed in the key and priority R&D plans drafted by the US, Japan and EU countries. Hence, the development of nanodevices and related basic research are of special strategic significance, as they are expected to play a critical role in socio-economic progress, national security and S&T development in China in the future.
The goal of this research project is to integrate key and advanced technologies in multi-disciplinary studies into the development of various nanodevices through bringing the CAS's advantages and strengths into full play. The CAS's efforts in this aspect will be focused on nanodevices related to informatics and bio-engineering, such as magneto-stochastic storage elements, uni-electronic elements, molecular devices and nano-optical bio-detectors. These will include the study of their working principles, design, assembly, construction and key technologies for industrialization. Centered on the development of nanodevices, relevant basic research and theoretical study will also be promoted so that from the very beginning of this project the nanodevices will be constructed with originality and effectivity.
Aimed at the study of fundamental issues and problems concerning the key know-how for industrial manufacture, the project will be implemented in three stages -- set for short-term, middle-term and long-term targets. On the one hand, the potential and advantages of the traditional technology of micro-electronics will be fully exploited from ``top to bottom" in the design and preparation of nanometric spin and quantum elements, such as those for magneto-stochastic storage; on the other hand, we cannot overlook the revolutionized changes in manufacturing technology and assembly of the nanostructure elements brought about by new concepts, new theories and new technologies through the "bottom to the top" approach. For some molecular devices, nanometric information storage devices and nanometric bio-devices noted for their promising prospects for making breakthroughs in the near future, we should be well prepared in advance to study their raw materials preparation, composition, structure, physical properties and device development, and to establish related means for their characterization in order to develop their prototypes as soon as possible.
Besides, in order to promote the industrialization of these nanodevices, it is advisable to further our efforts in applied research and technology. After obtaining a series of nano-storage devices, uni-electronic or molecular devices and bio-transducers, it is expected that fundamental breakthroughs will be made in the preparation and application of advanced materials. Last but not least, the measuring and debugging systems for protein chips will be developed and improved to promote the industrialization of optical protein chips.
To sum up, several key S&T problems concerning nanodevices will be targeted in this research project. Based on the fundamental study of nanoscience, an interdisciplinary system is to be introduced, including trans-disciplinary marriage of physics, chemistry, electronics, optics, micro-electronics, materials science, engineering science, etc. With such a system, it is expected that original and innovative concepts will be sparked. Through understanding and grasping nanodevices' working principles, design and related technology for operation and characterization, some basic problems and theories in nanoscience will be deeply explored. This will push our research up to the world's advanced level. Meanwhile, highly competent professionals specializing in basic research and development of nanodevices will be trained and nurtured so that several renowned research groups with considerable influence in the international arena of nanotechnology might be established soon in this country.
