We computationally investigate the transmission efficiency through moth-eye nanostructures that are fabricated on $\mathrm{SiO}_{2}$ windows in the wavelength range from 0.4 to 2 $\mathrm{\mu m}$. We investigated both truncated cones and…

CO-terminated tips currently provide the best spatial resolution obtainable in atomic force microscopy. Due to their chemical inertness, they allow to probe interactions dominated by Pauli repulsion. The small size and inertness of the…
