TL;DR: An advanced method for measuring the Young's modulus of thin and flexible nanostructures is proposed and consists of measuring the flexibility (the inverse of stiffness) profiles 1/k(x) by the scanning probe microscopy with precise control of loading force in nanonewton range followed by simulations.
Journal ArticleDOI
Passivation of GaAS surface by ultrathin epitaxial GaN layer
TL;DR: In this paper, the effect of passivation on the surface recombination rate of quantum well (QW) structures is characterized using low-temperature (10 K) photoluminescence.
Journal ArticleDOI
Demonstration of longitudinally polarized optical needles.
TL;DR: This work directly verifies the creation and full three-dimensional verification of a longitudinally polarized optical needle, produced by generating a radially polarized Bessel-Gauss beam at the focus of a high numerical aperture microscope objective.
Journal ArticleDOI
High-speed InGaAsP/InP multiple-quantum-well laser
TL;DR: In this article, the authors describe practical high-speed InGaAsP/InP lasers based on compressively strained quantum wells, with threshold currents of 10 mA and slope efficiencies of 0.23 mW/mA.
Journal ArticleDOI
Surface-tension driven self-assembly of microchips on hydrophobic receptor sites with water using forced wetting
TL;DR: In this article, a water droplet self-alignment method for self-assembly of microchips on hydrophobic receptor sites in ambient air environment is reported, which is possible using two forced wetting methods: (a) introducing an excessive amount of water and (b) applying external pressure.
