采用溶胶-凝胶法制备了非晶锌锡氧化物(ZTO)薄膜晶体管(TFT)
通过热重-差热分析(TG-DTA)对ZTO胶体中的化学反应进行了分析
研究了不同退火温度对ZTO TFTs性能的影响。结果表明:当退火温度在300~500℃范围内时
薄膜为非晶态结构
薄膜表面致密、平整。当退火温度达到400℃时
薄膜在可见光范围内具有高透过率(

Zinc-tin-oxide (ZTO) thin film transistors (TFTs) were fabricated by sol-gel method. Thermogravimetric and differential thermal analyses (TG-DTAs) were performed to investigate the chemical reactivity in the ZTO solutions. The effects of annealing temperatures on characteristics of ZTO-TFTs were investigated in this paper. With the increasing of annealing temperatures
all samples are amorphous
and surface is uniform. The ZTO thin films annealed at 400℃ and 500℃ are highly transparent (

85%) in the visible region. When the annealing temperature increased from 300℃ to 500℃
the threshold voltage of solution-processed ZTO TFTs decreased from 15.85 V to 3.76 V
and the saturation mobility increased from 0.004 cm
