Abstract When argon is used as a protecting gas in the fabrication or working environment of a nanodevice. absorption of some argon atoms onto the surface of the device lead to different responses. In this work. the rotation of the rotor in a carbon nanotube (CNT)-based rotary nanomotor in argon environment is investigated. https://www.roneverhart.com/Seagate-Exos-7E2-ST1000NM0008-1TB-7-2K-RPM-SATA-6Gb-s-512n-128MB-3-5-Hard-Drive/
