I-FIM is pleased to announce that PhD student Leonid Elesin has received the 2.5DM Student Poster Award at the RPGR 2025 conference, held from 3–7 November 2025 in Toyama, Japan. The official list of award recipients is available on the RPGR website: RPGR 2025 Award Winners
RPGR—Research Progress in Graphene and 2D Materials—is the premier annual conference in the field of graphene and van der Waals materials, bringing together leading researchers from around the world to discuss breakthroughs in 2D materials physics, engineering, and device applications.
Leonid’s poster, titled “THz Driven Photo-Thermoelectricity and the Nernst Effect in a Gate-Defined p–n Junction Based on a Graphene Moiré Superlattice,” presents new insights into terahertz-driven thermoelectric and Nernst effects in designer graphene superlattices. His results highlight how gate-defined p–n junctions in moiré systems can serve as a platform for probing nonlinear transport phenomena in correlated 2D materials.
The 2.5DM Student Award recognizes outstanding poster presentations by early-career researchers. This year’s recipients represent top institutions across Asia, including the University of Tokyo, Seoul National University, Nanjing University, Kyushu University, and many more.
RPGR began as a conference dedicated to graphene research, but has since evolved to cover a broad family of two-dimensional materials—such as hexagonal boron nitride, transition-metal dichalcogenides, layered oxides, and other emerging van der Waals systems—reflecting the rapid expansion of the field.
I-FIM congratulates Leonid on this recognition, and celebrates the continued achievement of our students in advancing cutting-edge research in 2D materials!
