Fifth-year PhD candidate in physics at University of Iowa, specializing in experimental characterization of crystal orientation, permittivity extraction from polarized cryogenic micro-FTIR measurements, near-field measurements of polaritons, transfer matrix and field simulations in van der Waals materials and heterostructures. Current research topics include phonon and exciton polaritons in low-symmetry van der Waals materials and their stacks.
Folland Lab Profile
Researchers from the University of Iowa, McMaster University, and Vanderbilt University have demonstrated an accurate and precise way to determine the crystal orientation of ultrathin layered materials.
University of Iowa researchers developed a flexible, cost-effective infrared cryogenic microscope for studying van der Waals materials at temperatures down to 4 K. The article features Ramachandra Bangari explaining its cooling system.
