This study documents experiments conducted in 2011 using ZnSnOx (ZTO) films synthesized via different methods, including Sn precursor and Tin(IV) chloride at 300ºC. The results show low mobility (~0.003) in initial samples and poor bias stress stability. Further research considerations include mobility enhancement to 0.026 cm2/vs, solution optimization, the role of acetic acid catalyst, and bias stress hysteresis analysis.
