Electron injection builds novel crystalline c.
Charge injection was widely utilized in tuning the energy level of electrons in semiconductors without altering their microscopic structures.
Recently, a research team led by Professor ZHU Yanwu from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) discovered another function of charge injection.
By charging C60 molecules periodically arranged in a face center cubic (fcc) lattice with a-Li3N, a novel long-range ordered porous carbon (LOPC) crystal was thereby formed.
The result was published in Nature .
Different from most elemental crystals in which building blocks are multifarious atoms, the building block for LOPC in this study is C60 molecule, commonly known as Soccerene or Buckyball.
LOPC possesses the characteristics of both long-range order in the three-dimensional (3D) crystal and partially broken C60 molecules connected as the building blocks.
At elevated temperatures and ambient pressure, a-Li3N would donate electrons to C60 molecules, which will cause the expansion of electron cloud surrounding C60.
