✦ Synopsis

Novel ZnSe•N 2 H 4 complex microrods with ~2 µm in length and 100~200 nm in diameter were successfully prepared by the solvothermal method at 110°C for 10 h, employing ZnAc 2 •2H 2 O and Se powders as the reactants, N 2 H 4 •H 2 O as the reductant and medium. Experiments showed that the as-obtained complex could be further converted into pure hexagonal ZnSe in an ethanol medium at 180°C for 10 h, and the morphology hardly changed. The as-prepared products were characterized by X-ray powder diffraction (XRD), Energy dispersive spectrum (EDS), IR spectrum, Thermogravimetric (TG) analysis and Field emission scanning electron microscopy (SEM). Also, their photocatalytic degradation and electrochemical properties were compared.

We propose a new valence control method, the ªcodoping method (using both n-and p-type dopants at the same time)º, for the fabrication of low-resistivity p-type GaN, AlN, ZnSe, CuInS 2 , and n-type diamond based upon ab initio electronic structure calculations. Based upon the calculation, we propose
