Growth And Characterization Of Organic Ferroelectric And Magnetic Thin Films, Xuanyuan Jiang
Growth And Characterization Of Organic Ferroelectric And Magnetic Thin Films, Xuanyuan Jiang
Department of Physics and Astronomy: Dissertations, Theses, and Student Research
Compared to inorganic materials, organic materials are environmentally friendly, flexible, and often with low cost. Inspired by these advantages, organic materials-based electronics have been intensively studied for comparable or better functionalities to inorganic electronics.
This dissertation mainly focuses on the growth and characterizations of organic ferroelectrics and magnetic thin films. For organic ferroelectrics, we investigate the growth and ferroelectric measurements of thin film croconic acid (CA), a proton-transfer molecular ferroelectric (FE) material with a large spontaneous polarization and a small coercive field, as well as the origin of ferroelectricity in CA in terms of the photostriction effect, including the discovery …
