Insights into the Microstructure and Transition Mechanism
Herein we systematically study the microstructure and doping site of Nd 3 -doped BSO using an unbiased CALYPSO structure search method in conjunction with first-principles calculations. The result indicates that the Nd 3 ion impurity occupies the host Bi 3 ion site with trigonal symmetry forming a unique semiconducting phase.

Jan 01 1990 · The doping of natural dolomite with 0.5 mole La203 and sintering at 1600C offers dense dolomite grains with a developed periclase-bonded network including most of the disseminated lime clusters. This La203 content is sufficient to inhibit the grain growth of lime clusters and meanwhile permits the development of a periclasc cluster network.
