Structure and energy-band diagrams of CdTe and cation-exchanged HgxCd1−xTe quantum dots (QDs). (a) Cd2+ replacement by Hg2+. (b) The potential energy wells (gray lines), quantum-confined kinetic energy levels (blue lines), and wave functions (red) of electrons and holes in CdTe and HgxCd1−xTe QDs, as calculated using the effective mass approximation.
