Abstract:
An oligothiophene-arylene derivative wherein an arylene having n-type semiconductor characteristics is introduced into an oligothiophene having p-type semiconductor characteristics, thereby simultaneously exhibiting both p-type and n-type semiconductor characteristics. Further, an organic thin film transistor using the oligothiophene-arylene derivative.
Abstract:
Disclosed herein are an alternating copolymer of phenylene vinylene and oligoarylene vinylene, a preparation method thereof, and an organic thin film transistor including the same. The organic thin film transistor maintains low off-state leakage current and realizes a high on/off current ratio and high charge mobility because the organic active layer thereof is formed of an alternating copolymer of phenylene vinylene and oligoarylene vinylene.
Abstract:
Disclosed herein is a multi-layered bipolar field-effect transistor, including a gate electrode, a gate insulating layer, an electron transport layer, a hole transport layer, a source electrode, and a drain electrode, in which an intermediate separating layer is formed between the electron transport layer and the hole transport layer, and a method of manufacturing the same. The multi-layered bipolar field-effect transistor has advantages in that, since a P-channel and a N-channel are effectively separated, the electrical properties thereof, such as current ON/OFF ratio, electron mobility, hole mobility, and the like, are improved, and, since a device can be manufactured through a solution process without damaging layers, the processability thereof is improved.
