Cd2Ge2O6 nanowires have been synthesized via a simple and facile hydrothermal route using GeO2 and CdO as the source materials with the surfactant. The structure and morphology of the Cd2Ge2O6 nanowires were fully analyzed by field emission scanning electron microscope (FESEM) and HRTEM. With a focused electron beam irradiation, the Cd2Ge2O6 nanowire became unstable and tended to heavily destroyed under a long time irradiation. Using the TEM-STM holder, electrical properties of an individual Cd2Ge2O6 nanowire has been measured and the obtained I-V curve demonstrated the semiconductor property.

AbstractThe crystallization of amorphous Ge2Sb2Te5 phase change material induced by electron beam irradiation was investigated by in-situ transmission electron microscopy (TEM). Amorphous matrix transformed into a partially crystalline state after being irradiated with a 200-keV electron beam for a long time. Real-time observation revealed that the crystallization of amorphous Ge2Sb2Te5 film occurs through a nucleation and growth mechanism under electron beam irradiation in TEM. While uncertainty from the 2D projection remains, the nuclei have been observed to grow preferentially along the < 100> direction.

This paper reported a method of multiwalled carbon nanotubes (MWCNTs) fusion inside a scanning electron microscope (SEM). A CNT was picked up by nanorobotics manipulator system which was constructed in SEM with 21 DOFs and 1 nm resolution. The CNT was picked up and placed on two manipulators. The tensile force was 140 nN when the CNT was pulled into two parts. Then, two parts of the CNT were connected to each other by two manipulators. The adhered force between two parts was measured to be about 20 nN. When the two parts of CNT were connected again, the contact area was fused by focused electron beam irradiation for 3 minutes. The tensile force of the junction was measured to be about 100 nN. However, after fusion, the tensile force was five times larger than the tensile force connected only by van der Waals force. This force was 70 percent of the tensile force before pulling out of CNTs. The results revealed that the electron beam irradiation was a promising method for CNT fusion. We hope this technology will be applied to nanoelectronics in the near future.
