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)
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 experimental works in the emerging field of quantum computing. The implementation of a(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)
I s the decades-long era of exponentially compounding improvements in the cost and performance of computing devices about to end? Can we sustain progress in information technology hardware by developing some new switching device that can be made smaller, faster, and cheaper than the silicon tran-sistor? These were some of the questions raised by a panel(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)
