《基于弛豫铁电单晶PMN-PT的新型器件（英文版）》一书介绍了基于铌镁酸铅-钛酸铅晶体(PMN-PT)设计开发的原型器件，初步探索了铁电材料在信息技术领域的新应用。首先，利用PMN-26PT单晶作为介电层，单层二硫化钼作为沟道半导体构筑了一种光热调控型场效应晶体管,为FET器件提供了一种新的策略。其次，采用银纳米线作为透明顶电极，在PMN-28PT晶体上单片集成了能够覆盖紫外至太赫兹范围的超宽光谱探测器。最后，通过集成摩擦电纳米发电机和铁电FET设计了一种自驱动模块。

Supervisor¡¯s Foreword As an important ferroelectric material, Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-PT) solid solutions combined the advantages of relaxor ferroelectric PMN and ferroelectric PT predictably. With the modi?ed Bridgman technique, large-size and high-quality PMN-PT single crystals have been successfully grown. The single crystals with the composition near the morphotropic phase boundary (MPB) exhibit ultra high piezoelectric constant of *2500 pC/N and large electromechanical coupling coef?cient up to 0.9. In recent years, piezoelectric devices based on the PMN-PT single crystals have received much attention and made a revolution in the elec- tromechanical transduction...
