In 2010, the author of a research paper studying graphene, the first material in history that can be one atom thick, received the Nobel Prize in Physics. Today, graphene hetero-structures are used as a substrate for elements in many new electronic devices (microcircuits, transistors, etc.).
"The combination of the electronic structures of graphene and graphene-like Ga-Se monolayer (g-GaSe) in an ultrathin hetero-structure has been realized experimentally. Our results show that the electronic properties of graphene/g-GaSe hetero-structures are stable. We found that the n-type Schottky contact is formed in the graphene/g-GaSe hetero-structure with a Schottky barrier height of 0.86 eV which can be efficiently modulated by applying an electric field, in-plane strains, and interlayer coupling," said Professor Viktor Ilyasov from the University's Physics Dept.
Scientists believe that they are very important for designing and manufacturing future graphene-based Van der Waals (vdW) hetero-structures, such as a graphene/g-GaSe hetero-structure, and for understanding the physics reactions in graphene-based 2D vdW hetero-structures.
Don State Technical University, the first Russian university to receive anchor regional-university status in February 2018, will serve as the main driving force of the Rostov Region's innovation development.
