Nano-Electronics Materials and Devices

-Focusing on Si MOSFETs and Nano-Carbon Devices-

Professor Takuo Sugano

Professor Emeritus, The University of Tokyo

Japan

Abstract:

As for the assessment of semiconductor technology, two concepts, "More Moore" and "More than Moore", have become popular since the International Technology Roadmap for Semiconductors 2007 made the definition clear.

Similarly the current research effort at nano-electronics can be categorized into the miniaturization of currently available devices to nano-meter range in their feature size along with the improvement of materials properties, and various exploratory researches on novel and emerging devices built with newly synthesized and conventional materials.

An example of R&D categorized into the former one is the scaling of Si MOSFET and narrowing the gate results one-dimensional electrons in the channel, which is frequently called "nano-wire". The behavior of carriers in the base region of bipolar transistor is three dimensional, but that in the channel of conventional MOSFET is two dimensional and will become one dimensional in advanced MOSFET. Zero dimensional electron can be found in so called “quantum dot, which is a key component of single electron transistor and quantum-dot laser. This technical trend demonstrates that the research and development are along with the progress of physics of electron system in solid and on the right track of advancement of application of low dimensional electrons to electron device.

Carbon nano-tube and graphene electronics illustrate the latter category of nano-electronics research. Electrons in carbon nano-tube are inherently one dimensional, so that semiconducting carbon nano-tube has been expected to be useful to build the channel of field effect transistor. The growth technology of carbon nano-tube has been much advanced by using catalyst, especially positioning, but alignment of growth direction and chirality are still not well controlled and much more efforts to solve these technological issues are needed to integrate carbon nano-tube FETs to electrical circuits. The low energy electronic states in graphene behave like those of two-dimensional massless Dirac fermions and intrinsic graphene is characterized as a semi-metal or zero-gap semiconductor. However various techniques to control the bandgap, such as confining electrons in graphene by forming nano-ribbons or applying electric field to bilayer graphene film and application to FET are explored.

In the assessment of nano-electronics materials and devices their capability for integration and compatibility with Si CMOS should be studied closely. For application to discrete devices such as sensor and detector those may not be serious issue, but for application to logic or memory circuit components those will be decisive in the determination of market size.

Nanostructured Materials Development in Korea

Professor Sang-Hee Suh

Director, Center for Nanostructured Materials Technology

Korea

Abstract:

Over the last 10 years Korea has put relatively large effort on nanotechnology development. Since Korean government started Korea Nanotechnology Initiative, we have seen tremendous increase in nanotechnology related publications, patents filed, new venture companies, and commercial products. Korea is now ranked high in the world in technological level in nanotechnology. This is partly due to large investment on nanotechnology by Korean government. Statistics on nanotechnology development in Korea will be introduced.

Sponsored by the Ministry of Education, Science & Technology of Korea, the Center for Nanostructured Materials Technology has been managing one of the biggest programs for developing nanotechnologies in Korea. This Program aims to develop various nanostructured materials with superior properties by creating new materials or by applying nanotechnology to the already existing materials. The R&D areas covered by the Program include nanostructured materials for structural applications, environment and energy applications, and information technology applications. Some of outstanding research accomplishments by the Program will be introduced.

Nanoscience Enabled Energy and Environmental Technologies

Professor Yi Cui

Department of Materials Science and Engineering, Stanford University

USA

Abstract:

In the past two decades, much fundamental understanding on nanoscale property has been established with chemically synthesized and lithographically patterned nanostructures. Rationally designed nanomaterials such as nanowires and nanocrystals afford the great opportunities for controlling electronic, photonic, mechanical and ionic processes, which are important for many applications. Here I will present examples on how to design and fabricate nanomaterials for high performance and/or low-cost energy conversion and storage applications including transparent electrodes, photovoltaics, batteries, supercapacitors and large-scale energy storage devices. I will also discuss exciting opportunities of exploiting nanoscience to address environmental problems.

IEEE NMDC 2010 Plenary Talk III (Oct 15)

Imaging Transport:

Monitoring the Motion of Charge through the Detection of Light

Professor Nancy M. Haegel

Physics Department

Naval Postgraduate School

USA

Abstract:

The ability to rapidly image phenomena at an appropriate scale of resolution often provides transformational insight into our understanding of the world. The ability to see what otherwise could only be assumed or inferred often challenges idealized assumptions or leads to the discovery of new phenomena. In this talk, a technique to “image transport” by monitoring the motion of charge via the recombination emission of light will be described. Transport imaging combines the potential resolution of near field optics with the charge generation control of a scanning electron microscope (SEM). Although the technique builds upon standard cathodoluminescence, it is significantly different, since it maintains the spatial information of the emitted light.

Results will be presented illustrating minority carrier drift behavior in heavily doped heterostructures, single-shot contact-free measurements of minority carrier diffusion in solar cell materials, observation of anisotropic diffusion in ordered ternary alloys and localized mapping of the transport effects of radiation damage. For spatial imaging beyond the diffraction limit, a near field scanning optical microscope (NSOM) has also been coupled to the electron beam system for transport imaging of nanowires. We present measurements for diffusion in core-shell AlGaN/GaN nanowires and preliminary results on transport imaging in ZnO nanowires and nanobelts.

Finally, a brief overview will be given of a range of research activity at the Naval Postgraduate School in nanotechnology and novel MEMs devices for security related applications.
