Using silicon etching techniques, free-standing micro gears and turbines were fabricated from silicon.

Essential to the construction of micro-mechanical systems is the ability to manufacture micro-mechanical components.

Robots bring to mind and are, for the most part, electromechanical systems on the scale of human beings.

This paper addresses the issue of micro-cells planning within macro-cell using a single UMTS carrier.

Local electronic states due to characteristic surface islands and pits formed on an atomically flat (110) GaAs interface of a quantum well fabricated by a cleaved-edge-overgrowth method with high-t

Micro-photoluminescence (PL) and micro-PL excitation (PLE) spectra were measured systematically in a 5 nm GaAs/AlAs single quantum well (QW) to investigate the predicted effect of asymmetric excito

Micro-Raman scattering measurements were used to study the phonon modes and to analyze the local variation of composition and strain in the micron range of AlxGayIn1-x-yAs materials grown in the re

Many integrated photonics applications require miniaturized on-chip sources over a wide wavelength range, such as coherent optical communication and spectroscopy.

In this work, we demonstrate for the first time a narrow-linewidth III-V-on-Si laser with more than 110 nm wavelength tuning range realized using micro-transfer printing (uTP) technology.

Semiconductor layers of InGaAsP and InGaAs grown in narrow gaps between SiO sub 2 stripes, which are separated by several microns, are important building blocks in modern optoelectronics.
