  • 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.

  • 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.
