dc.description.abstract | The complete ZnSxSe1−x solid solution was
successfully obtained by the mechanochemical process denoted
as a mechanically induced self-sustaining reaction. Excellent
control of the chemical stoichiometry of the solid solution was
possible by adjusting the atomic ratio of the starting Zn/S/Se
elemental mixture subjected to milling. A mixture of both
wurtzite-2H (hexagonal) and zinc blende (cubic) structures was
always obtained, although for a similar milling time the
proportion of the zinc blende structure increased with the Se
content in the solid solution. However, wurtzite was the major
phase for S-rich compositions when milling was stopped just
after ignition. It was demonstrated that milling induces the
wurtzite-to-zinc blende phase transition. The 8H hexagonal
polytype was also observed in samples subjected to long milling times. Variation of the lattice parameters for both structures
with the x value in the solid solution presented an excellent linearity, confirming the validity of Vegard’s law. However, variation
of the band-gap energy (Eg) with x was not perfectly linear, and a small bowing parameter of 0.34 was obtained. It was possible
to tune the Eg value between those of the end members of the solid solution in a continuous manner by adjusting the
stoichiometry of the solid solution. The morphology and crystalline domain size can also be controlled by adjusting, in this case,
the postignition milling time of the mechanochemical process. | es |
