摘要 采用LPMOCVD技术生长了InGaAs红外探测器器件结构材料,其晶格失配为2.19×10-4.利用锌扩散制备探测器单元器件,光谱响应范围为0.90~1.70μm,在1.95V偏压下,暗电流为5.75×10-5A,在反向偏压为-5V时,电容为6.96×10-12F.探测器波段探测率为2.08×1011cmHz1/2W-1. The In0.53 Ga0.47 As/InP used for infrared detector was grown by low pressure metal-organic chemical vapor deposition. The lattice mismatch is 2. 19 × 10^-4. The detector was fabricated by Zn diffusion. The range of spectral response is 0.90-1. 70μm. At a bias of 1.95V the dark current is 5.75 × 10^-5A, the capacitance at - 5V is about 6.96 × 10^-12F. The detectivity is 2.08 × 10^11 cmHz1/2W^- 1.
