Nanoscale imaging & spectroscopy application notes
neaspec’s neaSNOM was used by researchers at the CIC nanoGUNE to visualize how light moves in time and space inside an exotic class of matter known as hyperbolic materials. For the first time, ultraslow pulse propagation and backward propagating waves in deep subwavelength-scale thick slabs of boron nitride – a natural hyperbolic material for infrared light – could be observed.
neaspec GmbH and Fraunhofer IPM have developed a ready-to-use terahertz system that is capable of achieving a spatial resolution of 30 nanometers in combination with neaspec’s near-field microscope - neaSNOM
Using nano-FTIR neaSNOM it could be shown that thin-film organic semiconductors contain regions of structural disorder. These could inhibit the transport of charge and limit the efficiency of organic electronic devices.
The neaSNOM microscope equipped with a THz illumination unit were applied in ultrafast spectroscopy to take snapshots of super-fast electronic nano-motion. The scientists were able to record a 3D movie of electrons moving at the surface of a semiconductor nanowire.
