Andrii Iurov, Ph.D., an associate professor in the Department of Physics and Computer Science at the Medgar Evers College of the City University of New York, will present, “Temperature-Dependent Plasmons, Thermal-Convolution Paths, and Chemical Potential in Tunable Extrinsic Dirac Structures.”

In this talk, Iurov will present and discuss some of their recent results for the finite-temperature plasmons in graphene and other low-dimensional innovative materials in addition to graphene, such as silicene, germanene, and transitional metal dichalcogenides. They have also derived a set of analytical equations to calculate the chemical potential for all these various tunable extrinsic (or doped) Dirac structures and thermal plasmons controlled by different thermal-convolution paths. Furthermore, they have used the dynamical polarizability and random-phase approximation to study the split plasmon branches in buckled lattices and predicted a unique splitting, different from that in gapped graphene. Their results are crucial for stimulating new research into electronic, transport, and collective properties in the recently discovered lattices, photovoltaics, and transistor devices.

This event is open to alumni, faculty/staff, parents, students, and the public.
