TRANSISTOR ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a metal base organic transistor element (MBOT) which can be stably provided by a simple manufacturing process; which has a structure enabling mass production; and which has large current modulation and excellent on/off ratio under a low voltage between an emitter electrode and a collector electrode.SOLUTION: A transistor element comprises: a sheet-like base electrode 13 arranged between an emitter electrode 12 and a collector electrode 11; and p-type organic semiconductor layers (LiF) provided on both sides of the base electrode, respectively. The p-type organic semiconductor layers provided between the base electrode and the collector electrode are composed of p-type organic semiconductor polymer (P3HT).
