Title: Direct growth of metal nanoplates on semiconductor substrates

Abstract

Metal nanoplates are grown on n-type and p-type semiconductor wafer substrates through galvanic reactions between substantially pure aqueous metal solutions and the substrates. The morphology of the resulting metal nanoplates that protrude from the substrate can be tuned by controlling the concentration of the metal solution and the reaction time of the solution with the semiconductor wafer. Nanoplate size gradually increases with prolonged growth time and the nanoplate thicknesses increases in a unique stepwise fashion due to polymerization and fusion of adjacent nanoplates. Further, the roughness of the nanoplates can also be controlled. In a particular embodiment, Ag nanoplates are grown on a GaAs substrate through reaction with a solution of AgNO3 with the substrate.
