Nanoscale imaging & spectroscopy application notes
This E-Book summarizes applications of nanoscale investigation of inorganic materials in energy-storage, mineralogy, archaeology and corrosion sciences.
Researchers at the University of Stuttgart equiped with a neascope have now succeeded to observe switching processes at unattained nanometer resolution.
Researchers from Georgia employed nano-FTIR spectroscopy and IR nanoscale imaging for investigating how individual enveloped viruses (CoV, IFV, HIV, Ebola, etc.) enter into a host cell, revealing new membrane penetration mechanisms and inhibition processes for antiviral therapies.
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.
neaspec's neaSNOM microscope allows for launching and controlling light propagating along graphene, opening new venues for extremely miniaturized photonic devices and circuits
nano-FTIR beats the diffraction limit in infrared bio-spectroscopy and probes secondary structure in individual protein complexes
Two independent research teams have successfully used their neaSNOM infrared near-field microscopes for laying down a ghost: visualizing Dirac plasmons propagating along graphene, for the first time.
Near-field microscopy at infared and terahertz frequencies allows to quantify free carrier properties at the nanoscale without the need of electrical contacts.
Based on their unique near-field spectral signature infrared-active materials can be identified with neaSNOM.
Infrared near-field microscopy allows to study the propagation of surface waves in the infrared spectral regime. Amplitude and phase resolved...
Direct verification of superlensing can be achieved by near-field microscopy as the local field transmitted by a superlens can be investigated in the near-field of the lens.
Direct visualization of infrared light transportation and nanofocusing by miniature transmission lines is possible by amplitude- and phase-resolved near-field microscopy.
Amplitude and phase resolved near-field mapping of the local field distribution on resonant IR antennas can be used to analyze the antenna design and its functionality.
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.
Mapping nanoscale stress/strain fields around nanoindents in the surface of Silicon Carbide (SiC) crystals. Compressive/tensile strain occurs in bright/dark contrast respectively.
The local conductivity of nanowires can be investigated by infrared near-field microscopy.

The neaSNOM microscope with it’s imaging and nano-FTIR mode is the most useful research instrument in years, bringing genuinely new insights.
The neaSNOM near-field microscope and it’s user-friendly software offer us an incredible flexibility for the realization of our unique experiments – without compromises in robustness, handling and ease-of-use.
The great stability and robustness of the neaSNOM are key features for serving our diverse user’s demands. The neaSCAN software is user-friendly and intuitive allowing fresh users to quickly start measuring.
As a newcomer to the near-field optics I am very grateful for the prompt and competent support provided by neaspec’s experts.
We were looking for a flexible research tool capable of characterizing our energy storage materials at the nanoscale. neaSNOM proofed to be the system with the highest spatial resolution in infrared imaging and spectroscopy and brings us substantial new insights for our research.
After very successful scientific research with the neaSNOM microscope, we now decided to bring our research to the next level with the brand-new ultra-low temperature cryo-neaSNOM.
Our neaSNOM microscope enabled us to maximize our scientific output. It also strengthens the collaboration with several partners worldwide.
Surfaces & interfaces play an important role in physical chemistry. The neaSNOM microscope is the ideal tool to study two-dimensional materials, energy conversion & storage. It allows us full access to surface chemical information & modification at the highest spatial resolution.
The neaSNOM is the most powerful tool for plasmonic studies. It provides both, the spatial resolution and the complex field mapping, which is essential to the success of our projects.
We propose to establish a complete set of nano-FTIR and scattering-type SNOM in order to stay competitive in nanophotonics research as well as to maintain our state-of-the-art design and fabrication of novel nanomaterials. Only because of the unique technology from neaspec we were able to win this desirable university grant.
The neaSNOM microscope boosted my research in plasmonic properties of noble metal nanocrystals, optical resonances of dielectric nanostructures, and plasmon polaritons of graphene-like two dimensional nanomaterials.
The unique dual beam-path design of the neaSNOM near-field microscope makes neaspec the natural choice for ultrafast spectroscopy at the nanoscale.
The neaSNOM new imaging technique offers me the right tool to unravel the fascinating world of protein folding in complex biological systems at the nanoscale
A unique advantage of the neaSNOM microscope is that it can be applied to many fields of scientific research such as Chemistry, Semiconductor Technology, Polymer Science and even Life-Science.
I needed a flexible experimental platform with a high degree of optical access. The highly modular design of neaSNOM provides an ideal foundation for the development of my own experiments on top of it.
With its ultra-small & ultra-fast capabilities as well as the highly-compatible & user-friendly design, the neaSNOM near-field microscope offers us unique opportunities to uncover the intriguing nano-optical phenomena of novel two-dimensional materials.
As a near-field expert I was quickly convinced that neaSNOM is the only optical AFM microscope completely satisfying the needs of demanding near-field experiments. It’s the best comercially available technology and in addition really easy to use.
Developed by the s-SNOM experts, the neaSNOM microsocope is the ideal tool for our demanding applications. We work on characterizing opto-electronic devices like LEDs, transistors based on GaN and SiC as well as nanocomposites in e.g. textile fibers.
After many years of research and development in near-field microscopy, we finally made our dream come true to perform infrared imaging & spectroscopy at the nanoscale. With neaSNOM we can additionally realize Raman, fluorescence and non-linear nano-spectroscopy.
neaspec provides an ideal and reliable near-field optical microscope. Their expertise has proved invaluable in setting up my experiments.
Already after the first day of the system installation we have been able to measure publishable data.
