Direct determination of zero-field splitting for single Co${}^{2+}$ ion embedded in a CdTe/ZnTe quantum dot

J. Kobak, A. Bogucki, T. Smoleński +6

When Co${}^{2+}$ impurity is embedded in semiconductor structure, crystal strain strongly influences zero-filed splitting between Co${}^{2+}$ states with spin projection $S_z = \pm 3/2…
