“…In the presented work, we investigated field-emission properties of nanoporous carbon (NPC) [27][28][29][30][31][32][33][34]-one of all-carbon materials with disordered nanoscale structure. Due to developed pore/skeleton interface, homogeneity of pore size, strong adsorption ability, relatively high electric conductivity, and mechanical strength, the NPC materials give considerable promise for diverse applications, including manufacture of field electron emitters [35] for microwave, light, and X-ray sources, plasma devices, space thrusters, and microelectronic components and gauges.…”
