Tianjin University Makes Progress in the Research of Prediction of Single Crystal Shapes

 

Tianjin University Professor Hu Wenping from the School of Science carried out two advanced material research projects with researcher Li Rongjin and other partners. Their research results were published in Advanced Materials.

The accurate prediction and control of single crystal shapes are crucial in the fields of semiconductors, pharmacology, catalysts and others. The research team led by Professor Hu and his partners theoretically and experimentally proved that the Gibbs-Curie-Wulff Theorem was able to predict the equilibrium crystal shape of the organic crystals through their case study (Adv. Mater. 2016, 28, 1697). This research has provided the theoretical proofs regarding the accurate prediction of the organic semiconductor shape and the control of its growth process, with vital significance in the research of organic single crystals.

Recently, the team and their partners have successfully prepared 2D mica crystals with an atomically flat surface. This material, overcoming the shortcoming of the most commonly used ferroelectric polymer, was applied to the organic field-effect transistors (OFETs) with the dielectric layer. Therefore, a new organic nonvolatile multistate storage device based on OEFTs using mica as the 2D single-crystal electrets could be developed. This research result was published on the Back Cover of the Advanced MaterialsAdv. Mater. 2016, 28, 3755).

As one of the most prominent academic journals in the world, Advanced Materials includes the most cutting-edge and high-end papers in the field of material science.
