| 中文摘要:作为一种优秀的光吸收半导体材料，有
机-机杂化钙钛矿被广泛应用于光电领域。为了制备高
性能光电探测器件，采用溶液法制备了高度有序、超长的CH3NH3PbI3
纳米线，并将其应用于Au/CH3NH3PbI3/Au平面型光电探测器。该
器件具有宽的工作波段，在紫外-可见光-近红外(365~808 nm)
光谱范围内均有响应。其最大光响应度达到3.81 A·W-1，比探
测率为3.7×1011 Jones，开关比为4.9×103，光响应时间约
为7 ms。由于具有优异的光探测能力，该器件拥有广阔的应用前景。 |

| Abstract:As an excellent light absorption
semiconductor material, organic-inorganic hybrid halide
perovskite has been widely used in the field of optoelectronics.
To fabricate high performance photoelectric detection devices,
a highly ordered ultra-long CH3NH3PbI3 nanowire is
prepared by solution process and is used to fabricate an Au/CH3NH3PbI3/Au
planar photoelectric detector. The device has a wide operation
waveband. It has light response in the spectral range from
ultraviolet to near-infrared (365-808 nm). Its maximum
light responsibility (R), detectivity (D*), Ilight-Idark
ratio and light response time are up to 3.81 A·W-1,
3.7×1011 Jones, 4.9×103 and 7 ms respectively.
Because of excellent light detection ability, the device has a
wide application prospect. |
