ABSTRACT
We report experimental measurements of the field distribution of the light spot focused by a two-dimensional photonic crystal flat lens at wavelengths 1.51–1.58 μm. The photonic crystal slab is fabricated on a silicon-on-insulator substrate by focused-ion-beam direct milling. We confirm the light focusing by the photonic crystal slab through direct observation of the light spot entering into free space at the end facet of the slab lens. The beam profiles as the function of lateral position are measured and the minimal full width half maximum of the beam at 1.2 μm (0.77λ) is obtained.

    Indentation of a sharp (20 nm) cantilevered silicon tip into a polymer (SU8) surface is analyzed experimentally and through finite-element simulations. A rate effect on the microsecond scale that eases indentation is found, in contrast to the commonly observed hardening at high strain rates. The...

    N-type piezoresistance (PR) tensor component π44 is essentially independent of temperature and carrier concentration, but depends on them in higher impurity concentration (> 1020) since the Fermi level lowers due to the tail of the density-of-state (DOS). Although conduction effective masses...
