Beschreibung

This presentation provides an overview on recent research work of the department Technological Electronics at INA: (i) High resolution 3D Nanoimprint technology for nanosensors and nanoactuators. In the vertical direction sub-nm resolution for will be presented. (ii) Intelligent windows based on micromachined micromirror arrays. The mirror arrays are intended for implementation into windows of buildings to provide functionalities like daylight guiding into rooms, heat regulation and glare protection. Placed between the two panes of a window, these mirrors are maintenance-free and not subject to defilement. Further applications are artificial light guiding and light concentration for photovoltaic applications. 90° mirror rotation have been obtained by 40V requiring continuous power of 0.2mW/m2 for keeping positions. (iii) InP multiple air-gap filters and nanoimprinted Fabry Pérot filter arrays for sensorics and communication. The semiconductor multiple air-gap Fabry-Pérot filters show very large refractive index contrast and, thus, require only few periods in the Bragg mirrors. The multiple air-gap technology enables low actuation voltages and wide spectral tuning. 142nm have been tuned by 3.2V and 221nm have been scanned using 28V. Using nanoimprint cavities of different 3D structure in an array of Fabry-Pérot filters were generated in a single step. Filterarrays in the visible and IR range are demonstrated. (iv) A dual side 3D nanoimprint methodology which we call Self-Aligned Nano Shaping (SANS) is used to create 3D nanoparticles. First results are presented. Possible applications are pulmonal drug applications. Specific shapes are envisaged for pulmonal drug applications to overcome the macrophages in the lung and to avoid lung cancer.
