Thin film transistors have been fabricated using a mixture of organic semiconductors silica nanoparticles whose surfaces are chemically modified. The thin film transistors exhibit excellent electrical characteristics because of improved coatability on hydrophobic surfaces and improved crystallinity of organic semiconductors. New thin film transistor production processes have been established from the findings. Organic-inorganic hybrid bulk heterojunction solar cells have also been fabricated, and the device lifetime of the hybrid solar cells is found to be much improved in comparison with conventional organic solar cells. The interface density of states of the thin film transistor has been determined with impedance spectroscopy, and it is demonstrated that the density of states at the organic-inorganic hybrid gate insulator/organic semiconductor interface is extremely low, indicating that the hybrid materials are suitable to a gate insulator for thin film transistors as well.

薄膜晶体管是使用表面经过化学改性的有机半导体二氧化硅纳米粒子的混合物制造的。由于疏水表面上的可涂覆性得到改善以及有机半导体的结晶度得到改善，薄膜晶体管表现出优异的电特性。根据这些发现建立了新的薄膜晶体管生产工艺。有机-无机混合体异质结太阳能电池也已被制造出来，并且发现与传统有机太阳能电池相比，混合太阳能电池的器件寿命大大提高。利用阻抗谱测定了薄膜晶体管的界面态密度，结果表明有机-无机混合栅绝缘体/有机半导体界面处的态密度极低，表明该混合材料适合于也是薄膜晶体管的栅极绝缘体。
