Scientists develop method for fabricating individual magnetic quantum dots

(Phys.org)—Quantum dots are semiconductor crystals that contain a few hundred atoms constrained into such a small space they're considered zero-dimensional objects, often called "artificial atoms." Researchers have fabricated quantum dots made of various materials and sizes. Now in a new study, scientists have demonstrated how to fabricate individual magnetic quantum dots with pillar diameters as low as 250 nm, the smallest dot of this type reported to date.
