AI中文摘要：
我们演示了光导型PTCDA（3,4,9,10-苝四羧酸二酐）分子薄膜中的自旋泵浦诱导自旋输运，使用透明ITO（In₂O₃+SnO₂）薄膜作为自旋电流探测器。在由ITO/PTCDA/Ni₈₀Fe₂₀构成的三层堆叠结构样品中，通过Ni₈₀Fe₂₀层的铁磁共振驱动自旋泵浦，在PTCDA层中产生纯自旋电流；产生的自旋电流被吸收到ITO层中，因ITO层的逆自旋霍尔效应转换为电荷电流，并通过ITO电阻检测为电动势。此外，还研究了光照射对PTCDA薄膜自旋输运的影响。
英文摘要：
We demonstrate spin-pump-induced spin transport in a photoconductive PTCDA (3,4,9,10-perylene-teracarboxylic dianhydride) molecular thin film with a transparent ITO (In2O3 + SnO2) film as a spin current detector. In a tri-layer stacking structure sample composed of ITO/PTCDA/Ni80Fe20, pure spin current is generated in the PTCDA layer by using the spin pumping driven by the ferromagnetic resonance of the Ni80Fe20 layer. The generated spin current is absorbed into the ITO layer, converted to a charge current due to the inverse spin-Hall effect of the ITO layer, and detected as an electromotive force via the ITO resistance. Also, the light irradiation effect on spin transport in PTCDA films is investigated.
