Nanoelectronics, Nanophotonics and Nanomagnetism
Information- and communications technology (ICT) has experienced a tremendous growth the last 40 years. Especially, development within electronics, photonics and magnetism has lead to new, cost efficient components. A continued development of this field will, to a large extent, depend on nanotechnology.
In addition, electronic and optical properties on the nanoscale may become important for the development of new communication systems. Electromechanical systems also move towards the nano-level. By applying nanotechnology, both mass and dimensions can be reduced. This may, for example, lead to increased sensitivity of sensors for application in electronics, optics and biological systems. Studies of nano-scale magnetic structures facilitate application of the electron spin of different materials for many purposes.
Several directions of research within nanoelectronics, nanophotonics and nanomagnetism take place at NTNU. Perovskites is a class of materials with a large number of different physical properties, such as superconductivity, magneto-resistance and ferroelectricity. Several groups are engaged in this field. Photonic nanowires of GaAs for applications in eg. lasers and detectors is another field of research at NTNU, which depend to a large extent on nanotechnology.
