Defect Nucleation

One of the bottlenecks in realizing the potential of atom-thick graphene membrane for gas sieving is the difficulty in incorporating nanopores in an otherwise impermeable graphene lattice, with an angstrom precision at a high-enough pore density. We realize this design by developing a synergistic, partially decoupled defect nucleation and pore expansion strategy using O2 plasma and O3 treatment. A high density (ca. 2.1 × 1012 cm−2) of H2-sieving pores was achieved while limiting the percentage of CH4-permeating pores to 13 to 22 parts per million. As a result, a record-high gas mixture separation performance was achieved (H2 permeance, 1340 to 6045 gas permeation units; H2/CH4 separation factor, 15.6 to 25.1; H2/C3H8 separation factor, 38.0 to 57.8). This highly scalable pore etching strategy will accelerate the development of single-layer graphene-based energy-efficient membranes.

Graphene Membranes

The prospects for the use of single-layer graphene in the design of optical-acoustic converters (OAC) of a new generation are considered. It is shown that the limiting characteristics of transducers with single-layer graphene membranes can be obtained only in OACs constructed according to the Hayes scheme. The main characteristics of membranes – the main elements of OAC – are considered, and the physical properties of graphene, as the most preferred mate-rial for membranes, are analyzed. Estimates having been made show that the use of SLG gra-phene membranes makes it possible to create IR and THz radiation receivers with cells of the order of tens of microns with extremely high sensitivity. To achieve the maximum sensitivity, it is proposed to perform edge perforation of graphene membranes. A new design scheme of uncooled helium-graphene optoacoustic receivers with theoretically maximum sensitivity and speed and an operating range extended to helium temperatures is proposed. The de-scribed technical solutions can be used as the basis for the design of uncooled.
