In this study, the LaBₓNy/N-doped LaB₆ gate stack formation was investigated for pentacene-based organic field-effect transistors (OFETs) using a reactive sputtering process with LaB₆ target. Because the nitrogen-doped LaB₆ (N-doped LaB6) target is not commercially available currently, this work focused on N-doped LaB₆ electrodes and LaBₓNy insulator formations by the reactive sputtering utilizing conventional LaB6 target. The 10 nm thick LaBxNy deposited on p-Si(100) by the Ar/N2 flow ratio of 10/7 sccm showed negligible hysteresis in C-V characteristic with higher εr of 6.7 after 400℃/1min annealed in N2. The 10 nm thick N-doped LaB6 electrode deposited by the Ar/N2 flow ratio of 10/0.1 sccm showed the resistivity of 0.037 mΩcm after 400℃/1min annealed in N2. The N-doped LaB₆ electrode exhibited lower resistivity and improved interfacial stability with reduced leakage and frequency dispersion compared with Al/undoped LaB₆ electrodes. The pentacene-based OFET with LaBxNy/N-doped LaB6 gate stack showed high mobility of 0.76 cm2/Vs. |
