Single Crystal Growth of Quantum Materials

Doyle Temple, Norfolk State University

PEAQS has built a successful program in single crystal growth of quantum materials at NSU. In addition to the 800 square feet of research space previously allocated to PEAQS, NSU has leveraged the program to secure an additional ~1450 square feet of lab space, a $500k Department of Defense instrumentation grant for a new x-ray powder pattern diffractometer and an x-ray single crystal Laue diffractometer, and an NSF MRI grant for a Quantum Design Physical Properties Measurements System, which are needed for characterization of the the crystals grown by PEAQS students.

PEAQS students have begun to grow and characterize more than half a dozen new crystals, including CaFe2 4, Ba-doped CaFe2 4, CuBiz 4, MgCr204, BaFeGaO4, PdGa, and PiGa. The last two were characterized at the National High Magnetic Field Laboratory (NHMFL) by two NSU PEAQS undergraduates, Liam Harrigan and Kevin Allen.
