Russia developed graphene surface nanopore pore forming technology

Researchers at the Moscow State Iron and Steel Institute of the Russian National Research University have developed nanometer micropore hole-forming technology on the surface of graphene wafers by their colleagues outside the United Nations to control the aperture of the nanopore. The successful development of this technology opens up broader prospects for graphene applications. The corresponding results were published in the "Carbon" academic journal.

Ions, scandium, and other ions of different quality elements bombard graphene flakes at different energies. Ion bombardment energy is adjustable, and its maximum energy can reach 91 trillion electron volts. The experimental results show that the energy of the ion determines the pore size of the nanopore on the surface of the graphene sheet. The pore size of the nanopore formed can be set by adjusting the bombardment energy of the ion and make it vary between 1-4 nanometers. The study of this achievement has taken an important step towards the specific structure orientation of graphene materials.

Now, researchers of global graphene materials are researching and exploring methods for the controllable modification of graphene, including methods for generating defects in its structure, in order to change the microelectronic and conductive properties of graphene, and through induction. It has magnetic properties. Russian researchers are refining the process to form nano-micropores with controlled distances on the surface of the graphene sheet, which can be turned into semiconductor materials for use in the microelectronics industry.

Graphene with nanometer micropore has extremely wide application prospects in many fields, for example, it can be used for liquid purification, gene sequencing, and the like.
