Preparation and applications of transition metal oxide nanofibres and nanolines

Tätte T., Paalo M., Part M., Kisand V., Lõhmus A., Kink I., University of Tartu, EE

Recently many nanoscale silica structures have been suggested for optics device design. For example silica nanoneedles are used for focusing light into spot some tens of nanometers in diameter and sub-wavelength diameter silica fibres are [...]

Preparation of transparent electrodes based on CNT-s doped metal oxides

Paalo M., Tätte T., Visk U., Lõhmus A., Lõhmus R., Lõhmus A., Lõhmus R., Kink I., University of Tartu, EE

In recent year’s electrically conductive and transparent electrodes has been one of the most important issues in optoelectronics. High price of ITO have set the search for alternative materials into focus. CNT-s has been used [...]

1D transition metal oxide materials: preparation and applications

Tätte T., Paalo M., Talviste R., Kisand V., Saal K., Mäeorg U., Lõhmus A., Kink I., University of Tartu, EE

Recently many new technologies have been suggested for designing silica based optical devises in nanoscale. However, there are insuperable drawbacks in realizing optics based on silica (glass and quartz) because of their low refractive indexes. [...]

Preparation of Sb Doped SnO2 SPM Tips and their Use as Transparent Probes in STM Induced Light Hybrid Microscopy

Tätte T., Jacobsen V., Paalo M., Branscheid R., Kreiter M., Mäeorg U., Saal K., Lõhmus A., Kink I., Tartu University, EE

Development of various kinds of sharp needles has been in focus of investigators since their application as sensors in scanning probe microscopy. Although transparent and conductive tips lead to several fascinating applications like STM/SNOM hybrid [...]
