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 device was 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 width was 3mm. We observed a typical current-voltage (I-V) characteristics in CuPc FET with different electrode materials.

We have seen the effects of hole-injection buffer layer in organic light-emitting diodes using copper phthalocyanine(CuPc), poly(vinylcarbazole)(PVK), and Poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate)(PEDOT:PSS) in a device structure of ITO/buffer/TPD/$Alq_3$/Al. Polymer PVK and PEDOT:PSS buffer layer was made using spin casting method and the CuPc layer was made using thermal evaporation. Current-voltage characteristics, luminance-voltage characteristics and efficiency of device were measured at room temperature with a thickness variation of buffer layer. We have obtained an improvement of the external quantum efficiency by a factor of two, four, and two and half when the CuPc, PVK, and PEDOT:PSS buffer layer are used, respectively. The enhancement of the efficiency is attributed to the improved balance of holes and elelctrons due to the use of hole-injection buffer layer. The CuPc and PEDOT:PSS layer functions as a hole-injection supporter and the PVK layer as a hole-blocking one.

Organic field-effect transistors (OFETs) are of interest for use in widely area electronic applications. We fabricated the organic field-effect transistor based a copper phthalocyanine (CuPc) as an active layer on the silicon substrate. The CuPc FET device was made a topcontact type and the substrate temperature was room temperature and $150^{\circ}C$. The CuPc thickness was 40 nm, and the channel length was $50{\mu}m$, channel width was 3 mm. We observed the typical current-voltage (I-V) characteristics and capacitance-voltage (C-V) in CuPc FET and we calculated the effective mobility with each device. Also, we observed the AFM images with different substrate temperature.

An organic field-effect transistor (OFET) was fabricated using a copper phthalocyanine (CuPc) as the active layer on the silicon substrate. The CuPc FET device was configured as a top-contact type. The substrate temperature was room temperature. The CuPc thickness was 40 nm, and the channel length and channel width were 100 ${\mu}m$ 3 mm, respectively. Typical current-voltage (I-V) characteristics of the CuPc FET were observed and subsequently compared to the UV/ozone treatment on substrate surface.

최근에 유기물 전계효과 트랜지스터의 연구는 전자 소자 분야에서 널리 알려져 있다. 특히 본 연구에서는 CuPc 물질을 기본으로 하여 소자를 제작하고, 또한 기판의 온도를 달리 하여 CuPc/Au 구조 소자의 표면 전위 특성을 측정하였다. 기판은 slide glass를 사용하였고, CuPc 박막파 Au 전극은 진공 증착법을 이용하였다. 측정 온도의 범위는 0 - $100^{\circ}C$이었으며, 모든 측정은 진공 상태에서 측정이 이루어 졌다. 상온에서의 표면 전위 값은 약 600mV의 값을 보이고 있으며, 기판의 온도가 $100^{\circ}C$일 때 표면 전위 값은 약 500mV의 값으로 감소하는 것을 알 수 있다. 이러한 표면 전위 값의 변화는 기판의 온도가 상승하면서 CuPc 벌크 박막의 특성이 변화하는 것으로 판단되며, AFM 측정을 통해 확인 할 수 있었다.
