| Abstract_FL | Based on finite difference time domain method (FDTD) and finite element method (FEM),the mechanism of Pt/CdS and InSb ultraviolet-infrared dual-color focal-plane arrays was investigated.It was found that a high ultraviolet photo response can be achieved for Pt/CdS Schottky junction under an ultrathin Pt top contact.Further simulations show that the ultrathin top contact can efficiently couple the infrared radiation for the dual-color focal-plane array detector.The center to center spacing of each pixel of 50 μm in the ultraviolet and infrared dualcolor focal-plane array detector based on Pt/CdS and InSb junctions can significantly reduce crosstalk.Our work provides fundamental guidance for optimization and design of ultraviolet and infrared dual-color detector. |

| Notes | dual-color focal-plane arrays, Pt/CdS ultraviolet detector, InSb infrared detector 31-1577/TN Based on finite difference time domain method （FDTD） and finite element method （FEM）, the mechanism of Pt/CdS and InSb ultraviolet-infrared dual-color focal-plane arrays was investigated. It was found that a high ultraviolet photo response can be achieved for Pt/CdS Schottky junction under an ultrathin Pt top contact. Fur- ther simulations show that the ultrathin top contact can efficiently couple the infrared radiation for the dual-color focal-plane array detector. The center to center spacing of each pixel of 50 tzm in the ultraviolet and infrared dual- color focal-plane array detector based on Pt/CdS and InSb junctions can significantly reduce crosstalk. Our work provides fundamental guidance for optimization and design of ultraviolet and infrared dual-color detector. LI Qing1,2, BAI Jie1, LV Yan-Qiu3, HU Wei-Da1 , CHEN Xiao-Shuang1, LU Wei1 （ 1.
