Tsung-Yo Tsai Award Candidate Temperature-dependent electrical and mechanical properties of sputtering different doped ZnO thin films
Tsung-Yo Tsai,Chuen-Lin Tien,Po-Han Chen,Po-Wei Lee,Chi-Hong Huang,Sheng-Yun Wang,

Two kinds transparent conductive oxide films, AZO and GZO, were deposited by radio-frequency sputtering on NBK7 glass substrates. We measured and compared the temperature-dependent resistivity and residual stress properties. The results show that the resistivity of AZO thin films decrease with increasing the RF power, but that of GZO is increasing. The residual stress values of AZO thin films increase with increasing the RF power in the range of 60-100 W, but the residual stress values of GZO thin films decrease. Both resistivity and compressive stress in AZO and GZO thin films decrease as the heating temperature increases from room temperature to 90℃.
