BaZnO2因其空間群為P3121而被歸類為非中心對稱材料。屬於α石英族，BaZnO2為其中一種最常用的壓電材料。據文獻，BaZnO2被視為最具發展性的材料之一，因此激起學者研究的動力。
本研究中，以兩階段溶熱法製備BaZnO2並以 XRD，SEM，以及TEM分析其特性。結果顯示含有BaZnO2相以及BaCl2 和 BaCl2˙H2O等雜質。以I-V特性圖量測壓電相關特性來佐證成功合成BaZnO2。且以熱離子發射擴散理論來計算蕭特基障壁高度之改變。

BaZnO2 is classified as a noncentrosymmetric material with a space group P3121. It belongs to the α- quartz family which is one of the most used piezoelectric material. According to literature, first principle studies predicted that BaZnO2 can be a promising candidate as a piezoelectric material, thus motivating this research.
In this study, BaZnO2 was fabricated using a two-step solvothermal synthesis. XRD, SEM and TEM were used to characterize BaZnO2. The results revealed the BaZnO2 phase along with some impurities such as BaCl2 and BaCl2˙H2O. The existence of BaZnO2 was confirmed by investigating its piezo-related properties. I-V measurements were performed and the results showed the piezotronic property of BaZnO2. The Schottky barrier height variation was also calculated using the thermionic emission-diffusion theory.
The photocatalytic and piezophotocatalytic properties of BaZnO2 were also studied by decomposing methylene blue (MB) solution under visible light illumination. In the piezophotocatalytic experiment, both stress and ultrasonic vibration were introduced into the system. The results showed that the degradation capability of BaZnO2 was enhanced thus confirming its piezophotocatalytic property. The photocurrent of BaZnO2, which is approximately 0.7μA/cm2, was measured using a three-electrode configuration of a photoelectrochemical cell.
