Abstract
This article proposes a novel field-emission light source (FELS) with a simplified structure that can be operated under low-pressure conditions. The flat-format FELS, driven by a porous silicon (PS)-based planar electron emitter, exhibits bright luminescence at a low field emission current density of approximately $5~\mu $ A/cm2 even at the ambient pressure as high as $10^{{2}}$ Pa. This suggests the favorable energy conversion efficiency for this FELS device. Moreover, this novel FELS achieves reduced thermal effects and power consumption due to its lower driving voltage and conduction current compared with the conventional device. The repeatability within 8% and the stability below 3% of the PS planar emitter further supports its potential for FELS applications. As a promising on-chip electron source, the PS-based cold cathode opens avenues for future high-performance, low cost, silicon-compatible FELS with large area and operation at ambient pressure.
本文提出了一种结构简单、可在低压条件下工作的新型场发射光源(FELS)。在高至$10^{{2}}$ Pa的环境压力下,由多孔硅(PS)基平面电子发射器驱动的平板格式FELS在约$5~\mu $ a /cm2的低场发射电流密度下也表现出明亮的发光。这表明该FELS装置具有良好的能量转换效率。此外,与传统器件相比,该新型FELS具有更低的驱动电压和传导电流,从而降低了热效应和功耗。PS平面发射极的可重复性在8%以内,稳定性低于3%,进一步支持了其在FELS应用中的潜力。作为一种很有前途的片上电子源,基于ps的冷阴极为未来高性能、低成本、大面积、环境压力下运行的硅兼容FELS开辟了道路。
