Item Elastic behavior of the germanium nanowire membrane(2019-05-08) Bodepudi, Revanth; Liechti, K. M.Semiconductor nanowires promise to provide the building blocks for a new generation of nanoscale devices. Recently, researchers have worked on developing new membranes out of semiconductor nanowires. Due to its small dimensions and porous network structure, obtaining the mechanical properties of these membranes is very challenging. This work presents a bulge test method for determining the mechanical properties of the porous germanium nanowire membrane. Theoretical bulge equations for circular and rectangular shaped samples were derived. A parametric analysis was conducted to determine the optimum configuration and guide the selection of components for the apparatus. A laminate comprising the germanium nanowire membrane and a polymer film was fabricated due to the porosity of the nanowire membrane. The bulge test apparatus was designed and developed to test circular and rectangular shaped composite samples that are required to extract Young’s modulus and Poisson’s ratio. The Young’s modulus and the Poisson’s ratio of the germanium nanowire membrane were found to be 208 MPa and 0.10, respectively
