“…Inorganic ac-EL devices with a double-insulating-layer structure, which is very similar to our organic ac-EL device structure, have been studied. 13,14) The emission mechanism of these inorganic ac-EL devices is understood to be the impact excitation of luminescent centers by hot electrons injected from the interface states between the phosphor layer and insulating layer via high-field assisted tunneling. The charge velocity of electrons for the inorganic EL devices is estimated to be approximately 1:0 Â 10 8 cm s À1 assuming that the electron mobility to be 1:0 Â 10 2 cm 2 V À1 s À1 and applied field of 1:0 Â 10 6 V cm À1 .…”

Zonal flows, thought crucial to the saturation and self-regulation of turbulence and turbulent transport in magnetically confined plasmas, have been observed and characterized in the edge region of DIII-D plasmas. These flows exhibit temperature scaling characteristics and spatial features predicted for geodesic acoustic modes (GAMs), a class of higher-frequency zonal flows seen in nonlinear simulations of plasma turbulence. The zonal flows (GAMs) have been observed in the turbulence flow-field in the radial region 0.85 r/a 1.0 via application of time-delay-estimation techniques to two-dimensional measurements of density fluctuations, obtained with beam emission spectroscopy. Spatial and temporal analysis of the resulting flow-field demonstrates the existence of a coherent oscillation (approximately 15 kHz) in the poloidal flow of density fluctuations that has a long poloidal wavelength, possibly m = 0, narrow radial extent (k r ρ i < 0.2), and a frequency that varies monotonically with the local temperature. The approximate effective shearing rate, dv θ /dr, of the flow is of the same order of magnitude as the measured nonlinear decorrelation rate of the turbulence. These characteristics are consistent with predicted features of zonal flows, specifically identified as GAMs, observed in three-dimensional Braginskii simulations of core/edge turbulence.

Thin film EL &#8212; Prognosis for panel displays

Prognostication in the field of flat panel displays has historically been, at best, a sporty proposition. This has been notoriously true during the long turbulent history of attempts to capitalize on the intriguing possibility of large thin panels of "cold light" utilizing the phenomenon of electroluminescence (EL). Recent advances in deposition technology, a better understanding of the variable effects of the process, and a tractable set of solutions for achieving matrix control have, at long last, set the stage for an intrepid journey into prognostication once again. It is predicted that thin film EL will emerge as the dominant flat panel technology for a vast array of applications, eventually including the long awaited "hang on the wall TV". It is the writer's intent to illuminate the historical thread of events that he perceives as having led to these predictions and then to postulate future directions of this perceived thread of light. PATHWAYS TO THIN FILM ELNo attempt will be made, in even a superficial way, to cover the history of EL. That subject is far too long for the purpose at hand. Instead, selected avenues of effort that seem to have had significant bearing upon the perceived outcome are discussed briefly. For this reason, subjects such as dc EL will not be addressed.
