Brookhaven physicist Ivan Bozovic wants to understand why a thin-film insulator transitions to the superconducting state.
The resistance of superconductivity to rational explanation has prompted Brookhaven National Laboratory to fabricate atomically perfect ultra-thin-films capable of accurately characterize the transition from an insulator to superconductor. A normally insulating copper-oxide material (cuprate) was configured like the channel of a field-effect transistor (FET), using molecular beam epitaxy to create an atomically perfect superconducting film.
