Subedi selected for prestigious AVS national student award

June 20, 2023

Arjun Subedi, a Ph.D. graduate student in the Department of Physics and Astronomy at the University of Nebraska-Lincoln, has been selected for one of the 2023 AVS (American Vacuum Society) national student awards. He is one of the eight finalists who will be given the awards.

The title of his abstract is Temperature Dependent Magnetic and Electronic Properties of NiCo2O4 Thin Film Surfaces. “We have observed that in-plane spin polarization of unoccupied state, above Fermi level, of NiCo2O4 thin film surfaces decrease with increasing temperature, and the film could undergo metallic to non-metallic phase transition when the temperature was increased. Based on our findings, we have proposed a modified Arrhenius-type model for change in the observed binding energy of a core energy level of insulating thin films with change in temperature,” said Subedi.

Each year the AVS awards committee selects eight finalists out of numerous nominations around the world for the national student awards. The awards for this year will be presented at AVS 69th International Symposium and Exhibition on November 8, 2023, in Portland, Oregon. The award consists of a cash prize, a certificate, and reimbursed travel expenses.

Subedi works under the supervision of Prof. Peter Dowben and Prof. Takashi Komesu in collaboration with Prof. Xiaoshan Xu’s group, and the research is funded by the EPSCoR RII Track-1: Emergent Quantum Materials and Technologies (EQUATE), Award No. OIA-2044049 and Nebraska Public Power District through the Nebraska Center for Energy Sciences Research at the University of Nebraska-Lincoln.

AVS is an international community of scientists, engineers, and instrument manufacturers, which strives to promote research and communicate knowledge in the important areas of surface, interface, vacuum, and thin film science and technology for advancing humankind.
