Novel Applications of Terahertz Quantum Cascade Lasers: Gas Spectroscopy, Active Control & Nearfield Imaging
… A scattering type nearfield microscope (s-SNOM) with a better than λ/1000 resolution has been demonstrated with a tuning fork based atomic force microscope (AFM) and a partially suppressed THz QCL. The detection scheme is also harnessing the self-mixing effect. Compared with conventional …

Development of a multipurpose near-field imaging platform
… scanning near-field optical microscopy (s-SNOM) functionalities - all compatible with cryogenic operation. As a result of the simplicity and modular design, the system can be readily reconfigured to fulfill the requirements of different samples or to accommodate other material analysis …

Electronic properties and microstructure of nanoparticulate silicon systems for diode applications
… scanning near-field optical microscopy (IR s-SNOM) were employed to investigate the micro-scale as well as the meso-scale structure of the printed particle networks and, more importantly the structure of the interface between particles. A close contact between lattice planes of different …

Development of Active Terahertz Modulators for use with Quantum Cascade Lasers and Near-Field Imaging of their Individual Resonators
… scanning near-field optical microscopes (SNOM), which can provide subwavelength resolution. Furthermore, they showed the bonding and anti-bonding modes of the sub-wavelength features. For future direct integration of metasurfaces with the QCL facet inside the cryostat, the development of a …

Interface engineering and multi-modal characterization of co-evaporated metal halide perovskite films for efficient perovskite-silicon tandem solar cells
… scanning near-field optical microscopy (IR s-SNOM) and, for the first time, demonstrating nanoscale X-ray photoemission electron microscopy (XPEEM) on ultra-thin (5–20 nm) MHP films and buried interfaces, we reveal that insufficient MeO-2PACz coverage hinders organic precursor incorporation …

Scattering Scanning Near-Field Optical Microscopy on Anisotropic Dielectrics
Near-field optical microscopy allows the nondestructive examination of surfaces with a spatial resolution far below the diffraction limit of Abbe. In fact, the resolution of this kind of microscope is not at all dependent on the wavelength, but is typically in the range of 10 to 100 nanometers. On …
