研究了在不同热膨胀系数的(111)铂衬底上制备的(001)单轴取向(Al0.8Sc0.2)N薄膜的纯机械应变对铁电性的影响。采用不同热膨胀系数的衬底成功地控制了薄膜的机械晶格应变,尽管薄膜的成分相同。这些薄膜的剩余极化(Pr)和矫顽场(EC)值的变化可以用代表纤锌矿结构的晶体各向异性的内部参数来理解。这些结果表明,(Al1-xScx)N薄膜的铁电性质可以通过晶体各向异性来调节。
The effect of pure mechanical strain on ferroelectricity was investigated for (001)-one-axis-oriented (Al0.8Sc0.2)N films deposited on (111)Pt-coated substrates with different thermal expansion coefficients. The mechanical lattice strains were successfully controlled by using substrates with different thermal expansion coefficients, though the composition of the films is the same. The changes in the remanent polarization (Pr) and coercive field (Ec) values of these films can be understood by the internal parameterurepresenting crystal anisotropy of a wurtzite structure. These results suggest that the ferroelectric properties of (Al1–xScx)N films can be tuned via crystal anisotropy.
