Li-doped ZnO Piezoelectric Sensor for Touchscreen Applications

Abstract—Piezoelectric sensors based on highly (002)-oriented Li-doped Zinc Oxide (LZO) thin films are fabricated on Pt/Ti/SiO2/Si substrates using a Radio Frequency (RF) magnetron sputtering technique with DC-bias voltages ranging from 0 ~ 25 V. The DC-bias voltage modifies the microstructure and thickness uniformity of the LZO films, and therefore changes their piezoelectric properties. The optimal value of the piezoelectric coefficient is obtained for a DC-bias of 20 V. The observation results suggest that the superior piezoelectric property is the result of an improved crystallization of the LZO film rather than a greater thickness uniformity. The feasibility of the optimal LZO-based piezoelectric sensor for touchscreen applications is demonstrated by means of a simple experiment.
