Controls of Al nanoparticles were achieved by an electron beam irradiation of 1020 e/cm2·sec on the room temperature stage in HRTEM. Al decahedra, which were firstly obtained from Al2O3 through oxygen atoms removal by electron stimulated desorption process in vacuum, migrated to gather, rotated and revolved around an irradiation center, and decreased their dimeter to coalesce. The driving force of their motion is momentum transfer from electrons which were spirally trajected in the magnetic field inside a pole piece. It is possible to propose a control/manipulation method of nanoscale boundaries using an electron beam.
