Our laboratory is studying the electrical
behavior of designer materials called
heterostructures, where very thin layers are
sandwiched together to engineer devices with new
function. In collaboration with a group working
on new organic semiconductors at UMN we have
perfected a technique for the growth of SrTiO3
thin films that allows us to electrically tune
the conductivity of organic and oxide conductors.
These devices can attain electron and hole
densities over 1014 cm-2, a ten-fold improvement
over conventional (SiO2-based) devices. Our work
opens up exciting new possibilities for
investigation of metallic, or even
superconducting properties of these fascinating
and useful materials.

Education One post-doctoral researcher (Dr.
Maria Torija), one graduate student (Ms. Jing
Wu), and one visiting summer student (Mr.
Christophe Jan) are being trained and educated
under this award. Outreach The PI, along with
students from several departments at UMN, was
involved in the volunteering effort for the
Materials Research Society Strange Matter
exhibit at the Science Museum of
Minnesota. Students demonstrated several
hands-on Materials Science experiments with
children and adults.
