Piezoelectric ceramics with high piezoelectricity and broad temperature usage range

Autor: Qinghu Guo, Fei Li, Fangquan Xia, Pengbin Wang, Xiaoyi Gao, Hua Hao, Hanxing Liu, Huajun Sun, Shujun Zhang

Publikováno v: Journal of Materiomics, Vol 7, Iss 4, Pp 683-692 (2021)

There is a general observation that the Curie temperature and piezoelectric property of the ferroelectric ceramics can be enhanced only at the expense of each other, i.e., higher piezoelectricity, lower Curie temperature, thus, limits their applicati

Tunable Phase Structure in Mn-Doped Lead-Free BaTiO3 Crystalline/Amorphous Energy Storage Thin Films

Autor: Jianlu Geng, Dongxu Li, Hua Hao, Qinghu Guo, Huihuang Xu, Minghe Cao, Zhonghua Yao, Hanxing Liu

Publikováno v: Crystals, Vol 13, Iss 4, p 649 (2023)

For dielectric energy storage materials, high polarization and high breakdown strengths are a long-standing challenge. A modulating crystalline/amorphous phase structure strategy is proposed by Mn-doping and annealing temperature to enhance the energ

The mechanism for the enhanced piezoelectricity in multi-elements doped (K,Na)NbO3 ceramics

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-9 (2021)

The mechanism for the enhanced piezoelectricity in (K,Na)NbO3 based ceramics has not been fully understood. Here, the authors find that the dopants induced tetragonal phase and the accompanying high-density nanoscale heterostructures are responsible
