Resonant Zener tunneling is investigated in a multiquantum-well p-i-n diode at cryogenic temperatures.
This paper presents a direct RF sampling fourth-order bandpass Delta-Sigma A/D converter for multi-carrier 3G wireless base stations.
By spanning an optical octave (> 300 THz) with a broadened femtosecond laser frequency comb, we directly measure the frequencies of optical standards at 1064/532 nm, 633 nm and 778 nm in terms o
We report diffuse scattering studies of liquid layers on the Pb (110) and (111) surfaces at temperatures substantially below the melting point of Pb.
We consider the problem of linear polyphase blind equalization (BE), i.e. we are interested in equalizing the output of a single-input-multiple-output (SIMO) channel, without observing its input.
Spread spectrum modulation is universally accepted in the hostile communication environments that occur in military communications.
The gas flow through a vacuum component can be continuous, transitional, or molecular depending: on the pressure range and geometries involved.
We report the complete spatio-temporal characterization of ultrashort light pulses using a self-referencing device based on shearing interferometry in the space and frequency domains.
We demonstrate a new general x-ray method for the direct determination of the structure of materials which are periodic in the two dimensions and aperiodic in the third (2D crystals), encompassing
Competing interactions and geometric frustration provide favorable conditions for exotic states of matter.
