  University of Jinan (UJN), Apr. 11, 2014: Professor Zhang Changwen of the School of Physics Science and Technology has made a series of achievements with his subject group in magnetic control and design of low dimensional nanostructured materials, providing a new breakthrough for the experimental fabrication and design of nanostructured magnetic materials and spintronic devices. Currently, his research paper entitled "First-principles study on ferromagnetism in two-dimensional ZnO nanosheet" was accepted for publication in Chem. Phys. Lett. 548, 60-63 (2012), a world famous journal, and was recommended for front cover article for the issue of No. 548 of the same journal. This paper is about ferromagnetism regulated by s-p atom in ZnO nanosheet of hexagonal cellular structure, which has attracted much attention from counterparts both at home and abroad.

    The Nobel Prize in Physics 2010 was awarded for graphene, a two-dimensional material with novel structure, rich physical meaning and great prospect of wide application. It has become one of the key hot topics and frontlines in the field of physics in recent years. However, the great challenge is still the large scale fabrication and magnetic control of graphene as well as its compatibility with Si-based semiconductor industry. Therefore, the experimental fabrication and performance control of quasi-graphene nanostructured materials have become another pursuit of scientific research workers. Prof. Zhang Changwen, collaborating with the School of Physics, Shandong University, takes advantage of molecular dynamics, density functional theory and Monte Carlo simulation technique and makes great achievements in such aspects as quasi-graphene nanostructure silicene [J. Phys. Chem. C, 116, 47011(2012)úČNano. Res. Lett. 7, 422(2012)], ZnO[Chem. Phys. Lett. 548, 60(2012)], AlN[J. Comput. Chem. 32, 3122 (2011),J. Phys. Soc. Japan, 81, 044705(2012)]. These achievements have explained the relationship between material morphology and substrate, nanoscale and growth temperature. They have pointed out the deficiency of nanoflake/belt/junction and ion doping as well as the influence of external electric field on charge transfer amount, inter atomic bonding and energy forming. They have also discovered the physical and chemical relationship of small molecules and molecular group on nanostructure and realized the performance optimization and functionalization of nanostructured materials. These achievements are of great value to the application and related experimental work of nano-electronic components and spintronic devices.
