【 摘 要 】

Abstract During the course of the grant we made the following scientific advances: • We developed a thorough understanding of piezoelectricity in antiferromagnetic wurtzite structure MnO. • We explained the absence of ferromagnetism in high quality samples of transition-metal-doped ZnO, and proposed a scheme for obtaining robust ferromagnetism in ZnO-based systems. • We demonstrated that the MgO-ZnO-CdO system is a promising candidate for the production of polarization field-effect transistors.
