- This is a high-pressure phase of CdTe. We use the data given for a pressure of 19.3 GPa.
Simple Orthorhombic primitive vectors:
\[
\begin{array}{ccc}
\mathbf{a}_1 & = & a \, \mathbf{\hat{x}} \\
\mathbf{a}_2 & = & b \, \mathbf{\hat{y}} \\
\mathbf{a}_3 & = & c \, \mathbf{\hat{z}}
\end{array}
\]
Basis vectors:
\[ \begin{array}{ccccccc} & & \mbox{Lattice Coordinates} & & \mbox{Cartesian Coordinates} &\mbox{Wyckoff Position} & \mbox{Atom Type} \\ \mathbf{B}_{1} & =& z_{1} \, \mathbf{a}_{3}& =& z_{1} \, c \, \mathbf{\hat{z}}& \left(1a\right) & \mbox{Te} \\ \mathbf{B}_{2} & =& \frac12 \, \mathbf{a}_{2} + z_{2} \, \mathbf{a}_{3}& =& \frac12 \, b \, \mathbf{\hat{y}} + z_{2} \, c \, \mathbf{\hat{z}}& \left(1b\right) & \mbox{Cd} \\ \end{array} \]References
