Publication number: 20180151379Abstract: A method of manufacturing a porous silicon (PSi) includes providing a semiconductor wafer; depositing a mask layer on a first side of the semiconductor wafer; patterning the mask layer to expose portions of semiconductor material of the semiconductor wafer; depositing a metal layer onto the patterned mask layer on a second side of the semiconductor wafer; and etching the semiconductor wafer where exposed by patterned portions of any of the mask layer and the metal layer thereby creating PSi regions at a surface of the semiconductor wafer. The method may further include patterning the metal layer prior to etching to form at least one electrode. The etching may include etching the semiconductor wafer with HF, a solvent, and hydrogen peroxide. The metal layer may form a plurality of electrodes segmented from each other.Type: ApplicationFiled: November 29, 2016Publication date: May 31, 2018Applicant: THE UNITED STATES GOVERNMENT AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: MATTHEW HENDERSON ERVIN, NICHOLAS WILLIAM PIEKIEL, CHRISTOPHER JAMES MORRIS, WAYNE ANTHONY CHURAMAN

Patent number: 9165721Abstract: An electrical component includes an inkjet-printed graphene electrode. Graphene oxide flakes are deposited on a substrate in a graphene oxide ink using an inkjet printer. The deposited graphene oxide is thermally reduced to graphene. The electrical properties of the electrode are comparable to those of electrodes made using activated carbon, carbon nanotubes or graphene made by other methods. The electrical properties of the graphene electrodes may be tailored by adding nanoparticles of other materials to the ink to serve as conductivity enhancers, spacers, or to confer pseudocapacitance. Inkjet-printing can be used to make graphene electrodes of a desired thickness in preselected patterns. Inkjet printing can be used to make highly-transparent graphene electrodes. Inkjet-printed graphene electrodes may be used to fabricate double-layer capacitors that store energy by nanoscale charge separation at the electrode-electrolyte interface (i.e., “supercapacitors”).Type: GrantFiled: July 10, 2014Date of Patent: October 20, 2015Assignees: THE TRUSTEES OF THE STEVENS INSTITUTE OF TECHNOLOGY, THE UNITED STATES OF AMERICA, as represented by the Secretary of the ArmyInventors: Woo Young Lee, Linh Le, De Kong, Matthew Henderson Ervin, James L. Zunino, III, Brian E. Fuchs
