Over the past decade, a new approach to environmental analysis has developed. Although the scope and definition are not yet completely fixed, the new field of “industrial ecology” focuses on reducing the environmental impacts of goods and services, on systems-based analysis of environmental problems, and on innovations that can significantly improve(More)
The piezoelectronic transistor (PET) has been proposed as a transduction device not subject to the voltage limits of field-effect transistors. The PET transduces voltage to stress, activating a facile insulator-metal transition, thereby achieving multigigahertz switching speeds, as predicted by modeling, at lower power than the comparable generation field(More)
Most formal defi nitions of nanotechnology revolve around the study and control of phenomena and materials at length scales below 100 nm, whereas informal defi nitions almost always make a comparison with a human hair, which is about 80,000 nm wide. However, nanotechnology can mean diff erent things to diff erent people, which is why Nature Nanotechnology(More)
An IBM perspective M. Steffen D. P. DiVincenzo J. M. Chow T. N. Theis M. B. Ketchen Quantum physics provides an intriguing basis for achieving computational power to address certain categories of mathematical problems that are completely intractable with machine computation as we know it today. We present a brief overview of the current theoretical and(More)
Sophisticated microelectromechanical systems for device and sensor applications have flourished in the past decade. These devices exploit piezoelectric, capacitive, and piezoresistive effects, and coupling between them. However, high-performance piezoresistivity (as defined by on/off ratio) has primarily been observed in macroscopic single crystals. In this(More)
The insights contained in Gordon Moore's now famous 1965 and 1975 papers have broadly guided the development of semiconductor electronics for over 50 years. However, the field-effect transistor is approaching some physical limits to further miniaturization, and the associated rising costs and reduced return on investment appear to be slowing the pace of(More)
