摘要

摘要通过金属有机化学气相沉积，开发了基于数字 InGaAs/GaAs 变质缓冲层的 InGaAs 光电二极管结构的外延生长技术。基于所制结构的光电二极管的光电流光谱依赖性在 1.24 μm 波长处具有最大值。在室温下，峰值 10%时的光敏范围为 1.17-1.29 μm。研究了 9-300 K 温度范围内的电流-电压特性。结果表明，暗电流由生成-重合和隧道分量组成。室温下的暗电流密度为 8 × 10-5 A/cm2，反向偏压为 -5 V。

MOCVD Growth of InGaAs Metamorphic Heterostructures for Photodiodes with Low Dark Current

Abstract

The epitaxial growth technique of InGaAs photodiode structures based on a digital InGaAs/GaAs metamorphic buffer layer by metalorganic chemical vapor deposition has been developed. The spectral dependence of the photocurrent of photodiodes based on the produced structures has a maximum at the 1.24 μm wavelength. The photosensitivity range at 10% of peak is 1.17–1.29 μm at room temperature. The current-voltage characteristics in the temperature range 9–300 K were investigated. It is shown that the dark current consists of generation-recombination and tunneling components. The dark current density at room temperature was 8 × 10^–5 A/cm² with a reverse bias of –5 V.
