Researchers at the University of Stuttgart equiped with a neaspec microscope have now succeeded to observe switching processes at previously unattained nanometer resolution.
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.
neaspec’s neaSNOM microscope allows for launching and controlling light propagating along graphene, opening new venues for extremely miniaturized photonic devices and circuits
Near-field microscopy at infared and terahertz frequencies allows to quantify free carrier properties at the nanoscale without the need of electrical contacts.
The high spatial resolution of infrared near-field microscopy allows for detailed studies of phase transitions in materials like the insulator-to-metal transition of vanadium dioxide (VO2) thin films.
The local conductivity of nanowires can be investigated by infrared near-field microscopy.
