In this paper, we summarise the development of off-axis electron holography on biological samples starting in 1986 with the first results on ferritin from the group of Tonomura. In the middle of the 1990s strong interest was evoked, but then stagnation took place because the results obtained at that stage did not reach the contrast and the resolution achieved by conventional electron microscopy.To...
Ge nanoparticles fabricated by ion implantation technique in SiO 2 thin film crystallise after irradiation with a high-energy electron beam. The crystallisation process depends on the irradiation fluence and flux. Irradiation with a fluence above 6x10 3 C/cm 2 results in cluster growth and above 4x10 4 C/cm 2 in crystallisation. An irradiation with flux below...
