研究领域:
无铅铁电压电材料 (减少污染,保护环境)
BiMO3 Bi-基铁电起源,铁电相变研究 [PRB 75 245209 (2007)]
ZnSnO3 新型无铅压电材料研发 [SSC 149 1849 (2009)]

BiFeO3 电子及光学性能 [SSC 149 641 (2009)]
BiFeO3 掺杂 Mn 元素及其影响 [Sci. Adv. Mater. 2 (2010) 184]
铁磁材料
铁 先前的实验及理论研究表明磁对力学性能有很大的影响,它能改变位错蠕变取向,进而软化弹性剪切模量。同时也导致材料发生BCC-FCC结构转变。实际上,磁的影响是通过磁交换相互作用(exchange interaction),我们已进行了相应的研究。[Phys. Rev. B 82, 144304 (2010)]
因瓦合金(不变钢,Invar alloy) Fe-Ni, Fe-Cr 合金,具有极小的热膨胀系数。一米长的超不胀钢在温度变化1K时膨胀长度约0.2微米。相应的研究正在进行。
超导材料
高温超导材料的用途非常广阔,大致可分为三类:大电流应用(强电应用)、电子学应用(弱电应用)和抗磁性应用。大电流应用如超导发电、输电和储能;电子学应用包括超导计算机、超导天线、超导微波器件等;抗磁性主要应用于磁悬浮列车和热核聚变反应堆等。2008年初,日本人发现了铁基超导体,引起了新一轮的全球研究热潮。对超导机理的研究有助于研发更高Tc的超导材料。此外,磁与超导的共存,使得磁的作用在铁基超导体材料中更重要。迄今为止,磁的作用还不清晰。
为理解磁有序对三种典型的具有代表性的1111-型 LaFeAsO, 122-型 BaFe2As2 和 111-型 LiFeAs 铁基超导体材料的影响,我设计了巧妙的计算方案,并给出了全面的物理图像. [http://arxiv.org/abs/1005.2121 ]
低维热电材料 (热产生电能,用于废热回收)
BiFeO3 热电性能预报 [手稿准备中]
铁电光伏材料
普通太阳能材料只能提供非常低的输出电压。最新报道表明,通过畴工程,铁电体能够提供异常大的电压输出。因此铁电光伏在太阳能发电方面具有独特的优势,从而具有诱人的前景。 (Nature Photonics 4, 134-135 (March 2010))。相关的物理图像及机理正在研究。
