Description

A nanotransistor is a transistor whose dimensions are measured in nanometers. Transistors are used for switching and amplifying electronic signals. When combined in the millions and billions, they can be used to create sophisticated programmable information processors.

  1. Nanoelectronics: The New Frontier?

    18 Apr 2005 | | Contributor(s):: Mark Lundstrom

    After forty years of advances in integrated circuit technology, microelectronics is undergoing a transformation to nanoelectronics. Modern day MOSFETs now have channel lengths of only 50 nm, and billion transistor logic chips have arrived. Moore’s Law continues, but the end of MOSFET scaling is...

  2. CMOS Nanotechnology

    07 Jul 2004 | | Contributor(s):: Mark Lundstrom

    In non-specialist language, this talk introduces CMOS technology used for modern electronics. Beginning with an explanation of "CMOS," the speaker relates basic system considerations of transistor design and identifies future challenges for CMOS electronics. Anyone with an elementary...

  3. Transistors

    04 Aug 2004 | | Contributor(s):: Mark Lundstrom

    The transistor is the basic element of electronic systems. The integrated circuits inside today's personal computers, cell phones, PDA's, etc., contain hundreds of millions of transistors on a chip of silicon about 2 cm on a side. Each technology generation, engineers shrink the size of...

  4. Self-Heating and Scaling of Silicon Nano-Transistors

    05 Aug 2004 | | Contributor(s):: Eric Pop

    The most often cited technological roadblock of nanoscale electronics is the "power problem," i.e. power densities and device temperatures reaching levels that will prevent their reliable operation. Technology roadmap (ITRS) requirements are expected to lead to more heat dissipation problems,...

  5. Exponential Challenges, Exponential Rewards - The Future of Moore's Law

    14 Dec 2004 |

    Three exponentials have been the foundation of today's electronics, which are often taken for granted—namely transistor density, performance, and energy. Moore's Law captures the impact of these exponentials. Exponentially increasing transistor integration capacity, and exponentially...

  6. Electronic Transport in Semiconductors (Introductory Lecture)

    25 Aug 2004 | | Contributor(s):: Mark Lundstrom

    Welcome to the ECE 656 Introductory lecture. The objective of the course is to develop a clear, physical understanding of charge carrier transport in bulk semiconductors and in small semiconductor devices.The emphasis is on transport physics and its consequences in a device context. The course...

  7. Faster Materials versus Nanoscaled Si and SiGe: A Fork in the Roadmap?

    20 Apr 2004 | | Contributor(s):: Jerry M. Woodall

    Strained Si and SiGe MOSFET technologies face fundamental limits towards the end of this decade when the technology roadmap calls for gate dimensions of 45 nm headed for 22 nm. This fact, and difficulties in developing a suitable high-K dielectric, have stimulated the search for alternatives to...

  8. Digital Electronics: Fundamental Limits and Future Prospects

    20 Jan 2004 |

    I will review some old and some recent work on the fundamental (and not so fundamental) limits imposed by physics of electron devices on their density and power consumption.

  9. A Personal Quest for Information

    19 Feb 2004 |

    This talk will report results and conclusions from my personal investigations into several different disciplines, carried out with the unifying intent of uncovering some of the fundamental principles that govern representation, processing, and the communication of information. The specific...

  10. Nanoelectronics and the Future of Microelectronics

    22 Aug 2002 | | Contributor(s):: Mark Lundstrom

    Progress in silicon technology continues to outpace the historic pace of Moore's Law, but the end of device scaling now seems to be only 10-15 years away. As a result, there is intense interest in new, molecular-scale devices that might complement a basic silicon platform by providing it...

  11. Electronic Transport in Semi-conducting Carbon Nanotube Transistor Devices

    16 Oct 2003 | | Contributor(s):: Joerg Appenzeller

    Recent demonstrations of high performance carbon nanotube field-effect transistors (CNFETs) highlight their potential for a future nanotube-based electronics. Besides being just a nanometer in diameter, carbon nanotubes offer intrinsic advantages if compared with silicon that are responsible for...

  12. Quantum-dot Cellular Automata

    24 Nov 2003 |

    The multiple challenges presented by the problem of scaling transistor sizes are all related to the fact that transistors encode binary information by the state of a current switch. What is required is a new paradigm, still capable of providing general purpose digital computation, but which can...
