| Outline of Final Research Achievements |
1. In situ TEM manipulation possibilities for “nanoarchitectonics”: We demonstrate precise manipulation of multiple nanowires with nanoscale accuracy and in situ TEM creation of hetero-junctions between them. Optoelectronic tests are carried out on them using light, introduced inside the TEM column through an optical fiber. 2. Opto-mechano-electrical tripling in ZnO nanowires: We observe that in situ bent ZnO nanowires exhibit an opto-mechano-electrical tripling phenomenon, due to the electronic structure changes in the expanded/compressed regions of the wire, in excellent agreement with theoretical simulations. 3. Statistically analyzed photoresponse of elastically bent CdS nanowires: Using in situ electrical probing and light illumination, we measure the optoelectronic features of individual CdS nanowires under elastic bending, while visualizing deformation features. Our statistical analysis shows that the ON/OFF ratios of the wires do not change due to bending deformation.
