Finite-size effects in bismuth nanowires
Arrays of semimetallic Bi nanowires, fabricated by electrodeposition, exhibit strong finite-size effects in transport properties as the carrier mean-free path is limited by the wire dimensions. We have observed a resistivity enhancement, a very large positive magnetoresistance, and a resistance maximum that depends on the strength and orientation of the magnetic field and the nanowire diameter....
متن کاملStrong elasticity size effects in ZnO nanowires
Recently, zinc oxide (ZnO) nanowires have drawn major interest because of their semiconducting nature and unique optical and piezoelectric properties. Various applications for ZnO nanowires have been conceived, including the next generation of field effect transistors, light emitting diodes, sensors and resonators. ZnO nanowires are also envisioned as nanogenerators by exploiting the coupling o...
متن کاملThermal conductivity suppression in bismuth nanowires
The thermal conductivity of individual bismuth nanowires was characterized using a suspended microdevice and correlated with the crystal structure and growth direction obtained by transmission electron microscopy on the same nanowires. Compared to bulk bismuth in the same crystal direction perpendicular to the trigonal axis, the thermal conductivity of a single-crystal bismuth nanowire of 232 n...
متن کاملOscillating electrical conductivity in bismuth nanowires
In the recent past, extensive studies were performed on nanoscale materials. In particular, bismuth nanowires attracted large interest because of their extraordinary electronic properties and potential application in future thermoelectric devices. When the nanowire diameter becomes comparable to the electronic mean free path le and the Fermi wavelength λF, finite-size and quantumsize effects (Q...
متن کاملElectrical transport properties of single bismuth nanowires
Due to its unique electronic properties bismuth is of enormous interest for studies on the nanoscale. In particular, when the object size is comparable to the mean free path of charge carriers le (~ 100 nm and ~ 400 μm at 300 and 4 K, respectively [1]), mesoscopic effects such as electron scattering at both surface [2] and grain boundaries [3] become significant. For investigating the influence...
