Keithley™ 2460 Sourcemeter

Electrochemical Etching Apparatus

Keithley™ 2460 Sourcemeter, with Labview™ computer interface. This is a multi-purpose programmable power supply (Source-Measure Unit, or SMU) that can source and measure current and voltage (Max Voltage: 100 V; Max Current: 7 A).  In the MCF, the instrument is configured to perform two-electrode electrochemical anodization. Primarily used to prepare porous silicon films, microparticles, and nanoparticles by electrochemical anodization, it can also be used to prepare mesoporous alumina, and to perform electroplating or electrocorrosion processes. The Labview™ program interfaced to the unit allows generation of user-defined current-time waveforms that can be used to fabricate photonic crystals, Bragg stacks, microcavities, Fabry-Perot layers, microparticles, and nanoparticles (including porous silicon quantum dots). The SMU and computer are configured on a wheeled cart that can be transported to the user’s location if needed. Facility also has available a Keithley™ 2651A Sourcemeter available, which can source currents up to 50 Amperes.
