论文摘要
我们提出了超薄有机多层设备的异质结理，这是我们先前工作的修订。它们的特征是在偏置电压应用下的绝缘中性介电区域中的导电空间电荷区域的产生，而在半导体的情况下，在导电中性区域中产生绝缘空间电荷区域。我们提出了准通用器的概念来描述这些特征。从理论中，给出了移动载体的电容器方程，这是半导体物理学中莫特 - 索特基方程的等效方程。因为有机物是介电，所以动力学是通过极化巧妙地控制的。该理论给出了应用电压，载体积累，迁移率和载体密度之间的关系，这可以同时评估迁移率和超薄有机多层设备的载体密度。 qiasicoductor的概念是有机电子和半导体物理学之间缺少的联系。
We present a heterojunction theory of ultrathin organic multi-layered devices, which is the revision of our previous work. Their characteristic feature is the generation of conductive space charge region in the insulating neutral dielectric region under the bias voltage application, while the insulating space charge region is generated in the conductive neutral region in the case of semiconductors. We propose the concept of quasiconductor to describe these features. From the theory, the capacitor equation of mobile carriers is given, which is an equivalent equation of the Mott-Schottky equation in semiconductor physics. Because the organics are dielectrics, the dynamics are controlled cleverly by polarization. The theory gives a relation among the applied voltage, carrier accumulation, mobility, and carrier density, which enables the in-situ simultaneous evaluation of mobility and the carrier density of ultrathin organic multi-layered devices. The concept of quiasiconductor is a missing link between organic electronics and the semiconductor physics.
