Abstract

A 4 nm thick carbon layer was obtained by pulsed laser deposition in vacuum directly on the surface of an n-Ge wafer. The carbon played a role of an intermediate layer in Au/C-layer/n-Ge mesa-diodes allowing the formation of a photosensitive structure with a dark reverse current density of 0.026 A/cm², a barrier height of 0.6 V and a maximum spectral sensitivity in the wavelength range of 1.4–1.6 μm.

脉冲激光沉积碳层制备锗基肖特基二极管

采用脉冲激光真空沉积法在氮锗晶圆表面直接沉积了一层厚度为4nm的碳层。在Au/C-layer/n-Ge台面二极管中，碳起到了中间层的作用，形成了暗反向电流密度为0.026 a /cm2，势垒高度为0.6 V，最大光谱灵敏度在1.4 ~ 1.6 μm波长范围内的光敏结构。

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
