Thallium Telluride nanowire array
Cross-section back-scattered SEM image of Tl5Te3 nanowire array showing overgrowth. Light contrast shows nanowires in and overgrowth on porous aluminum oxide film.
Lead telluride nanowire leg
SEM image of lead telluride nanowire leg. Dark contrast shows nanowire array.
Nanowire array
Cross section backscattered SEM of nanowire array of Lead Telluride. Light contrast shows nano wires in dark contrast porous aluminum oxide film.
Filled porous aluminum oxide template
Optical image of polyaniline filled PAA template. The green coloration is indicitive of emeraldine - an electrically conductive form of polyaniline.
Measurement of a wire bundle
Probe tips being used to measure resistance of a spot welded bismuth telluride wire bundle at the CINT facility in Albuquerque
Electrodeposited tellurium
Tellurium growth, dark, on the platinum backing layer, white, of a template that was not properly insulated during deposition
Moving a nanowire
Manipulation of a single bismuth telluride wire at the CINT facility in Albuquerque
Nanowire fragments
Fragments of broken bismuth telluride nanowires seen after etching a sonicated Whatman® template
Electrodepostied and chemically converted zinc oxide
Zinc oxide growth on the surface of a porous alumina template
Etched porous alumina template with overgrowth
An etched alumina template. The hemispheres are overgrowth which have protected the alumina below them, resulting in unetched islands
Electrodeposited bismuth telluride
Cross section of overgrown bismuth telluride. The overgrowth and nanowires show the brightest contrast, while the template itself is a light grey
Electrodeposited tellurium
Collection of images showing uniform wire growth of tellurium across a full cross section of an array. The bright areas have wires, while the darker areas are unfilled.
Etched porous aluminum oxide
Cracks running through a full template which has been etched. The bright contrast areas are from the platinum backing layer.
Etched porous aluminum oxide
Top down view of a partially etched template. The grey areas are the unetched template, while the dark areas are unfilled.
