Describes a form of frequency divider circuit in which one of the two cross-connecting capacitors of the usual multi-vibrator circuit, is replaced by a network consisting of a circuit sharply tuned
We present photometric and spectroscopic observations of 15 high-redshift quasars (z > 3.6) discovered from similar to 140 deg(2) of five-color (u', g', r', i', and z') imaging data taken by the
We demonstrate high-reflectivity crack-free Al0.18Ga0.82N/Al0.8Ga0.2N distributed Bragg reflectors (DBR) for the spectral region around 350 nm grown by molecular-beam epitaxy on thick GaN templates
The place of the failure rate in characterizing the reliability of a component is discussed.
We have produced a high-resistance state at milliKelvin temperatures in several degenerately doped samples of Ge:As by the application of both sufficient [1,1,1] stress to force all of the conducti
High resolution electron microscope images of twin boundaries in Ba sub 2 YCu sub 3 O sub 7 show that the twin plane is the (110) plane containing the Cu, Ba, Y and O atoms and not the plane contai
High-resolution, high-energy, X-ray diffraction results are presented for the study of weak charge ordering phenomenon.
Spectroscopic methods involving the sudden injection or ejection of electrons in materials are a powerful probe of electronic structure and interactions.
Optical four-wave mixing resonances in sodium vapor induced by collisions with invert buffer gases (He,Ar,Xe,N2) are characterized at high resolution (5 MHz) using lasers tuned near the D-lines
We describe a transfer printing technique for directly patterning thin gold films onto GaAs surfaces.
