    EXAFS Studies of the Local Structure Around Zn in Cd1−x Zn x Te

    X-ray absorption spectroscopy has been used to obtain information on the local structure around Zn atoms in CdTe. The Zn–Te distance is 5% smaller than the Cd–Te bond-length in the bulk, but slightly larger th...

    The Effect of Si and Mg Do** in the Microstructure of Epitaxially Grown GaN

    The effect of p- and n-type do** (using Mg and Si, respectively) in the microstructure of GaN, grown epitaxially on (0001)Al2O3 and (111)Si, is studied with X-ray absorption measurements at the N-K-edge. A dist...
