Single-Crystal MgO Hollow Nanospheres Formed in RF Impulse Discharge Plasmas
Figure 6
SEM images of nanoparticles deposited near the electrode when Ar/O2 mixing ratio is 3/1 and total pressure is 0.1 Torr. There observed several nanoparticles with circular hole on the surface. These nanoparticles seem to be originally formed as hollow spheres.
