Electrical Properties of CuPc Field-effect Transistor with Different Electrodes

전극 변화에 따른 CuPc Field-effect Transistor의 전기적 특성

Organic field-effect transistors (OFETs) are of interest for use in widely area electronic applications. We fabricated a copper phthalocyanine (CuPc) based field-effect transistor with different metal electrode. The CuPc FET made a top-contact type and the substrate temperature was room temperature. The source and drain electrodes were used an Au and Al materials. The CuPc thickness was 40nm, and the channel length was $50{\mu}m$, channel device was width was 3mm. We observed a typical current-voltage (I-V) characteristics in CuPc FET with different electrode materials.
