    • A method for producing an organic semiconductor device (110) having at least one organic semiconducting material (122) and at least two electrodes (114) adapted to support an electric charge carrier transport through the organic semiconducting material (122) is disclosed. The organic semiconducting material (122) intrinsically has ambipolar semiconducting properties. The method comprises at least one step of generating at least one intermediate layer (120) which at least partially is interposed between the organic semiconducting material (122) and at least one of the electrodes (114) of the organic semiconductor device (110). The intermediate layer (120) comprises at least one thiol compound having the general formula HS-R, wherein R is an organic residue. The thiol compound has an electric dipole moment pointing away from the SH-group of the thiol compound. The electric dipole moment has at least the same magnitude as the electric dipole moment in 4-Phenylthiophenol. By the intermediate layer (120) an ambipolar charge carrier transport between the electrodes (114) is suppressed in favor of a unipolar charge carrier transport.
    • 公开了一种用于制造具有至少一种有机半导体材料(122)和至少两个电极(114)的有机半导体器件(110)的方法,所述至少两个电极(114)适于支持通过有机半导体材料(122)传输的电荷载体。 有机半导体材料(122)本身具有双极性半导体性质。 所述方法包括产生至少一个中间层(120)的至少一个步骤,所述中间层至少部分地介于有机半导体材料(122)和有机半导体器件(110)的至少一个电极(114)之间。 中间层(120)包含至少一种具有通式HS-R的硫醇化合物,其中R是有机残基。 硫醇化合物具有指向远离硫醇化合物的SH基团的电偶极矩。 电偶极矩与4-苯基苯硫酚中的电偶极矩至少相同。 通过中间层(120),电极(114)之间的双极电荷载流子传输被抑制以有利于单极电荷载流子传输。
