摘要
随着GaAs负电子亲和势(NEA)半导体光电阴极在我国的成熟和应用,半导体光电阴极的进一步研究将往更长波的近红外发展。针对透射式半导体光电阴极器件,系统总结了近红外波段响应良好的GaAs、InGaAs、InGaAsP Ⅲ-V族外延材料特性及相应商业化产品的应用领域和性能。通过文献调研本文进一步归纳了不同波段NEA光电阴极和转移电子光阴极适用的材料结构,并结合传统GaAs NEA光电阴极工艺讨论了InGaAs、InGaAsP材料及阴极工艺的难点。
Abstract
With the maturity of GaAs negative electron affinity (NEA) photocathode in China, the research on semiconductor photocathode will move forward to longer near infrared wavelength. The property and device performance of III-V epitaxial material with high infrared response: GaAs, InGaAs and InGaAsP are compared. Suitable NEA and transferred-electron photocathode structure for different infrared wavelength detection are summarized and the key point in fabrication of InGaAs and InGaAsP photocathode is discussed.
