The spectral response, brightness, and outgassing characteristics of new, low-voltage phosphors for application in field emission flat panel displays, are presented. The tested phosphor materials include combustion synthesized powders and thin films prepared by rf diode or magnetron sputtering, laser ablation, and molecular beam epitaxy. These cathodoluminescent materials are tested with e-beam...

The properties of the filamentary microdischarges found in dielectric barrier discharges depend on the manner of charging of the dielectric. The charging of the dielectric removes voltage from the gap thereby reducing E/N and producing a transition from an avalanching discharge to a recombination or attachment dominated discharge. In this article, we report on a computational investigation of t...

With the rapid development of dc system, residual current in system has become an urgent problem to be solved. However, type B devices (RCD) for ac systems could not directly used systems. In voltage fluctuation generated by rectifier and circulating net currents line with different positive negative parameters would interfere detection RCD. this paper, experimental platform was built firstly. ...

Introduction: The dynamic range (DR) of CMOS imaging sensors is limited by the voltage space at the integration node. The DR can be nonlinearly expanded by scaling the integration time or the integration capacitance [1]. However, the imaging sensor’s linearity is low from these wide DR schemes. Biomedical and scientific applications require imaging with high linearity [2]. The self-resetting pi...
