Evidence of a ZnCr2Se4 Spinel Inclusion at the Core of a Cr-Doped ZnSe Quantum Dot- Dr. Strouse
Prof. Strouse’s recent article “Evidence of a ZnCr2Se4 Spinel Inclusion at the Core of a Cr-Doped ZnSe Quantum Dot”(DOI: DOI: 10.1021/ja210285p) in the Journal of the American Chemical Society was highlighted by Chemistry Views (DOI: 10.1002/chemv.201200037), an on-line magazine from Wiley-VCH and Chem Pub Soc Europe. The highlighted article addresses a recent discovery where intentional spinel inclusions can be formed within a quantum dot lattice. The exciting results suggest shifts the paradigm for making dilute magnetic semiconductor quantum dots (DMSQD), a material that holds the interest for chemists, physicist, and engineers alike due to the ability to manipulate s-p-d orbital exchange in an otherwise non-magnetic host lattice. Such DMSQD materials reflect the potential of such materials for quantum computing, spintronics, magneto-resistive, and magneto-optical applications. The reported manuscript by a INSI program member probes the underlying chemistry and physics of incorporating dopant ions into a growing quantum dot in order to control the magnetic properties of the materials. The effort by the Strouse group is part of a team of researchers including research from the National High Magnetic Field Laboratory (Prof. Dalal) and the University of Maine (Prof. Rob Meulenberg).
