Abstract
Wireless thin film transistor (TFT) structure has been studied to apply to various flexible or wearable devices. For employing micro antenna structure to TFT, the magnetic core (MC) is added to the micro antenna structure to enhance the delivered wireless power and signal due to the decrease of the power efficiency as the scale down of antenna size. The MC is consisted of ZnO nano-wires and Ni, a ferromagnetic material, which is coated on the vertical ZnO nano-wires. Due to the increase of self-resonance frequency with decreasing antenna size, we choose and fabricated a-IGZO TFT, which can have a higher mobility than a-Si TFT. The result enhances the wireless transferred power efficiency of the TFT with micro antenna structure.
无线薄膜晶体管(TFT)结构已被研究用于各种柔性或可穿戴设备。将微型天线结构应用于TFT时,由于天线尺寸缩小导致功率效率下降,因此在微型天线结构中增加了磁芯(MC),以增强传输的无线功率和信号。MC由ZnO纳米线和Ni组成,Ni是一种铁磁性材料,被涂覆在垂直的ZnO纳米线上。由于自共振频率随天线尺寸的减小而增加,我们选择并制作了a- igzo TFT,它比a- si TFT具有更高的迁移率。研究结果提高了微天线结构TFT的无线传输功率效率。
