Microchip construction for Seebeck-effect measurements on bismuth nanowires
The characterization of thermoelectric properties of nanoscale materials is a current topic of intensive research. Especially bismuth nanowires are very attractive because of their extraordinary properties and possible applications in thermoelectric devices. For the calculation of the thermoelectric figure of merit z = α2σ/λ, the Seebeck coefficient α, the electrical conductivity σ and the ther...
متن کاملDetermining the Shape of a Resistor Grid through Boundary Measurements∗
Impedance imaging has received a lot of attention in the past two decades, as a means for non-destructively imaging the interior of a conductive object. One injects a known electrical current pattern into an object at the exterior boundary, then measures the induced potential (voltage) on some portion of the boundary. The goal is to recover information about the interior conductivity of the obj...
متن کاملCircular resistor networks for electrical impedance tomography with partial boundary measurements
We introduce an algorithm for the numerical solution of electrical impedance tomography (EIT) in two dimensions, with partial boundary measurements. The algorithm is an extension of the one in [11, 49] for EIT with full boundary measurements. It is based on resistor networks that arise in finite volume discretizations of the elliptic partial differential equation for the potential, on so-called...
متن کاملDisposable screen-printed bismuth electrode modified with multi-walled carbon nanotubes for electrochemical stripping measurements.
Integrating the advantages of screen printing technology with the encouraging electroanalytical characteristic of metallic bismuth, we developed an ultrasensitive and disposable screen-printed bismuth electrode (SPBE) modified with multi-walled carbon nanotubes (MWCNTs) for electrochemical stripping measurements. Metallic bismuth powders and MWCNTs were homogeneously mixed with graphite-carbon ...
متن کاملFocused ion beam processing to fabricate ohmic contact electrodes on a bismuth nanowire for Hall measurements
Ohmic contact electrodes for four-wire resistance and Hall measurements were fabricated on an individual single-crystal bismuth nanowire encapsulated in a cylindrical quartz template. Focused ion beam processing was utilized to expose the side surfaces of the bismuth nanowire in the template, and carbon and tungsten electrodes were deposited on the bismuth nanowire in situ to achieve electrical...
