APPLIED PHYSICS REVIEWS The physics and technology of gallium antimonide: An emerging optoelectronic material

Recent advances in nonsilica fiber technology have prompted the development of suitable materials for devices operating beyond 1.55 mm. The III–V ternaries and quaternaries ~AlGaIn!~AsSb! lattice matched to GaSb seem to be the obvious choice and have turned out to be promising candidates for high speed electronic and long wavelength photonic devices. Consequently, there has been tremendous upth...

Emerging nanoscale silicon devices taking advantage of nanostructure physics

This paper describes the present status of research on emerging nanoscale silicon devices that take full advantage of new physical phenomena which appear in silicon nanostructures. This new physics includes quantum effects that enhance the performance of MOS transistors and single-electron charging effects that add new function to conventional CMOS circuits. These physical phenomena may be used...

AAPM / RSNA PHYSICS TUTORIAL 1213 AAPM / RSNA Physics Tutorial for Residents MR Imaging : Brief Overview and Emerging Applications 1

Magnetic resonance (MR) imaging has become established as a diagnostic and research tool in many areas of medicine because of its ability to provide excellent soft-tissue delineation in different areas of interest. In addition to T1and T2-weighted imaging, many specialized MR techniques have been designed to extract metabolic or biophysical information. Diffusion-weighted imaging gives insight ...

Signal processing for molecular and cellular biological physics: an emerging field

Recent advances in our ability to watch the molecular and cellular processes of life in action--such as atomic force microscopy, optical tweezers and Forster fluorescence resonance energy transfer--raise challenges for digital signal processing (DSP) of the resulting experimental data. This article explores the unique properties of such biophysical time series that set them apart from other sig...
