Photoelectrochemical Etching of InAs
Photoelectrochemieal etching of n-InAs (Eg = 0.36 eV) is demonstrated. Although the concentration of thermally generated minority carriers and saturation current are high compared to larger bandgap semiconductors, photocurrent to dark current ratios as high as 4:1 were obtained at low temperature (2°C) and at potentials near the flatband potential. A surface film primarily composed of arsenic o...
متن کاملMacroscale Transformation Optics Enabled by Photoelectrochemical Etching.
Photoelectrochemical etching of silicon can be used to form lateral refractive index gradients for transformation optical devices. This technique allows the fabrication of macroscale devices with large refractive index gradients. Patterned porous layers can also be lifted from the substrate and transferred to other materials, creating more possibilities for novel devices.
متن کاملPhotoelectrochemical undercut etching for fabrication of GaN microelectromechanical systems
The authors have developed a wet, band-gap-selective, photoelectrochemical etching process capable of producing cantilever microelectromechanical systems from InGaN/GaN heterostructures. Fabricated cantilevers were successfully actuated, and resonance spectra were measured. The as-grown strain gradient in the GaN film was found to relax upon removal, resulting in upward curvature of the cantile...
متن کاملNumerical algorithms based on Galerkin methods for the modeling of reactive interfaces in photoelectrochemical (PEC) solar cells
This work concerns the numerical solution of a coupled system of self-consistent reaction-drift-diffusion-Poisson equations that describes the macroscopic dynamics of charge transport in photoelectrochemical (PEC) solar cells with reactive semiconductor and electrolyte interfaces. We present three numerical algorithms, mainly based on a mixed finite element and a local discontinuous Galerkin me...
متن کاملComputer simulation of PEC network
Interconnection network is a decisive component of parallel and distributed computer systems. With the merits of simplicity and eeciency, 2-dimensional (2-D) mesh has been a popular choice of large MIMD interconnection networks. Mesh, however, has its known weaknesses in scalability and connectivity. Packed Exponential Connections (PEC) is a newly proposed network which is designed to improve t...
