\end{equation}  In this model, A, B, C, and D are material parameters that depend on the material geometry. Refer to table 1 for parameter values at different quantum well thicknesses. Using this scheme, the band structure for HgTe/CdTe topological insulators can be calculated. As shown in figure 3a-c, the structure depends on the quantum well thickness greatly. At a critical thickness ($\approx 0.63${\AA}), the bands become inverted, indicating a toplogical phase change.  \begin{table} \begin{tabular}{l*{6}{c}r}  \caption{\label{tab:table1}This is a narrow table which fits into a}  \begin{ruledtabular}  \begin{tabular}{lcr} Team & P & W & D & L & F & A & Pts \\  \hline  1 Manchester United & 6 & 4 & 0  & 2 &3\\  10 & 20 5 & 12 \\  Celtic & 6 & 3 & 0 & 3 & 8 & 9 & 9 \\  Benfica & 6 & 2 & 1 & 3 & 7 & 8 & 7 \\  FC Copenhagen & 6 & 2 & 1 & 3  & 30\\  100 5  & 200 8  & 300\\ 7 \\  \end{tabular}\end{ruledtabular}  \end{table}
