Electron holography on dynamic motion of secondary electrons around sciatic nerve tissues.
By means of electron holographic visualization of detailed electric potential distribution around sciatic nerve tissues coated with C and OsO(4), we show that the steady state of these specimens subjected to intense charging with electron irradiation is accompanied with a dynamic motion of collective secondary electrons; the secondary electrons emitted from the coated specimens revolve around the positively charged specimens forming stationary orbits. Further, this study clarified the possibility of the direct visualization of a part of the orbits of the collective secondary electrons without disturbing their motions.
