![[Top]An atomic-resolution scanning tunneling microscopy (STM) image of an indium arsenide crystal surface where a manganese atom has been inserted in place of one of the indium atoms. The displaced indium atom appears as the bright yellow feature on the surface; the embedded manganese atom is only evident by its effect on the neighboring arsenic atoms (the dumbbell-shaped yellow feature). [Bottom] The theoretical simulation of the STM image after the atoms finish playing musical chairs, illustrating the origin of the features seen in the experiment.](/images/09CNST001_mn_substitution_C.jpg "[Top]An atomic-resolution scanning tunneling microscopy (STM) image of an indium arsenide crystal surface where a manganese atom has been inserted in place of one of the indium atoms.
