Positive ion-depleted region in ionic glasses

Solid State Ionics, 1992
Abstract ac measurements were made on lithium disilicate glass, with various bias voltages at constant temperature. Observed data were compared with those for (AgI) 75 (Ag 4 P 2 O 7 ) 25 glass, one of superionic conductors. Emphasis was given on the dependence of the complex admittance on bias amplitude, from which the nature of positive ion ...

Depletion region in thermally poled fused silica

Applied Physics Letters, 2000
The depletion-layer width and the recorded electric field in thermally poled fused silica are investigated experimentally as a function of the applied voltage. The depletion-layer width is observed to vary linearly with the poling voltage. The average electric field recorded in the depletion region was found to be (5.3±0.3)×108 V/m for all samples ...

Time evolution of depletion region in poled silica

Applied Physics Letters, 2003
The electric field recorded in silica samples thermally poled during various intervals was measured by etching. The field is nearly uniform and increases to a maximum (∼3.6×108 V/m) in few minutes of poling and subsequently decreases slowly toward a steady level (∼1.4×108 V/m).

Radiation Damage Coefficients for Silicon Depletion Regions

IEEE Transactions on Nuclear Science, 1979
An experimental and analytical study of radiation effects on silicon depletion regions has been performed. Data are presented which yield damage coefficients appropriate for describing the effects of fission neutrons and Co60 gamma rays on depleted regions and on the SiO2-Si interface.

Femtosecond carfier transport in nonuniform depletion regions

Optical Society of America Annual Meeting, 1990
We use excitonic effects in thin GaAs quantum-well stripline samples to generate, propagate, and detect femtosecond electrical signals.1 The time dependence of the initial photocurrent transient depends sensitively on the bias and excitation conditions.

D region depletions above the Persian Gulf

Journal of Atmospheric and Terrestrial Physics, 1993
Abstract The extraordinary delay of the daily variation of absorption and electron density observed in the ionospheric D region above the Persian Gulf in 1976 observed from the research vessel ‘Akademik Kurchatov’ may be a consequence of air pollution by oil production by-products.

Surface polaritons in semiconductor films with depletion regions

SPIE Proceedings, 1995
A theory of TM type surface polaritons in semiconductor films possessing depletion transition layer, in which electron concentration changes according to the law of hyperbolic cosine, was built. The influence of dissipative as well as non-dissipative damping, caused by plasma resonance in transition layer, on dispersion properties of normal and ...

Displacement damage extremes in silicon depletion regions

IEEE Transactions on Nuclear Science, 1989
Measurements of proton-induced dark current increases in a Si CID (charge injection device) imager have been made following displacement damage by 12- and 63-MeV protons. Populations of 61504 pixels optimize statistics and make possible the first detailed study of rare events.

Measuring regional economic impacts of streamflow depletions

Water Resources Research, 1997
Because of large upstream diversions for agriculture and an absence of policies to protect in‐stream flows, flows in the Rio Grande near Taos, New Mexico, routinely are low by midsummer. The reach is a popular Whitewater run in the southwestern United States when flows are adequate for river running. This article estimates the regional economic impacts

The motion of depleted plasma regions in the equatorial ionosphere

Journal of Geophysical Research: Space Physics, 1979
Depleted plasma regions in the equatorial ionosphere and their associated motions have been observed by a variety of ground‐based, rocket‐borne, and satellite instruments. Various theories, based primarily on the Rayleigh‐Taylor instability mechanism, have been proposed for the formation and motion of these bubbles.
