Abstract
MgO는 플라즈마 디스플레이 패널 (Plasma Display Panel, PDP)의 보호막으로 널리 쓰이고 있다. 본 실험에서는 산소 이온 빔을 이용하여 증착된 MgO 보호막의 특성을 조사하였다. MgO 증착 시 보조 산소 이온 빔의 에너지를 변화시킴에 따라 MgO 보호막의 특성과 PDP 패널 발광특성에 미치는 영향을 분석하였다. 본 연구에서는 산소 이온 에너지가 300 eV 일 때 소자의 방전개시전압이 가장 낮게 나타났고, 발광 휘도 및 발광 효율은 가장 높게 나타났다. 또한 산소 이온 빔의 조사에너지에 따라 MgO 박막의 결정성 및 표면조도가 크게 영향을 받는 것을 확인할 수 있었다. 산소 이온 빔 보조 증착 방법을 이용하여 패널의 발광 휘도와 발광 효율 등 발광특성을 개선하였다. The magnesium oxide (MgO) protective layer plays an important role in plasma display panels (PDPs). In this paper, we describe the structural and discharge properties of MgO thin films, which were prepared by the ion-beam-assisted deposition (IBAD) of oxygen as the protective layer of PDPs. The energy of the oxygen ion beam was used as the parameter to control the deposition. We found that the oxygen ion beam energy was effective in determining in structural and discharge characteristics. The lowest firing inception voltage, the highest brightness and the highest luminous efficiency were obtained when the MgO thin film was deposited with an oxygen ion beam energy of 300 eV. The crystallization of the MgO thin film was also measured by X-ray diffraction analysis, and the surface quality was measured by atomic force microscopy.
