The cutting procedure is conducted in less than 1 min using a low-energy electron beam inside a scanning electron microscope. The oxygen gas was regulated by a mass flow controller and was injected at 1 SCCM. It was found that although the total pressure inside the specimen chamber reached 10−2 Pa, high-speed cutting occurred only in an area close to the oxygen gas nozzle. They assume that the CNTs are cut only under a low acceleration voltage since the CNT molecules are easily excited and ionized by the low-energy electron beam.}, pages = {113104--113104}, title = {Cutting of carbon nanotubes assisted with oxygen gas inside a scanning electron microscope}, volume = {89}, year = {2006} }
