We have optically excited carriers and followed their recombination kinetics in order to determine the effects of the physical and chemical states of the semiconductor surfaces on their electronic

Infrared absorption spectroscopy is used to characterize the initial stages of oxidation of H-passivated Si(111) surfaces by inferring the coverage and local chemical environment of Si-H species th

We present far-induced reflectivity spectra of seven samples of ceramic superconductors in the Ba-Y-Cu-O system with transition temperatures near 93K.

The effect of uniaxial stress upon the helium-like infrared absorption spectrum of the oxygen donor in Si has been examined for both the neutral and singly ionized charge states.

SmMn(2)Ge(2) shows reentrant ferromagnetism. Using flux grown single crystals we find that on cooling through the Curie temperature (T(t1) = 350K) the material becomes ferromagnetic (FM).

Pairs of telephone wires are often packed closely together in large numbers. These wires may belong to a cable or lie together on a shelf as jumper wires of a main distribution frame.

Recently, Fredman and Tarjan invented a new, especially efficient form of heap (priority queue) called the Fibonacci heap.

Crystals of composition (Ca sub (0.86) Sr sub (0.14)) CuO sub 2 have been grown and characterized by single crystal X-ray diffraction. The crystals are tetragonal with space group P4/mmm (No.

Many technologies have revolutionized life throughout the history of humanity, from the creation of hand tools, mechanical devices, powered machines and automated robotic processes and manufacturin
