dc.description.abstract | This work demonstrates an anisotropic increase in resistivity with decreasing width in single crystal tungsten (W) nanowires having a height of 21 nm. Nanowire-widths were in the range of 15-451 nm, with the anisotropy observed for widths below 50 nm. The longitudinal directions of the nanowires coincided with the < 100 >, < 110 > and < 111 > orientations of the body centered cubic phase of W. The resistivity increase was observed to be minimized for the < 111 >-oriented single crystal nanowires, exhibiting a factor of two lower increase in resistivity at a width of similar to 15 nm, relative to the thin film resistivity (i.e., an infinitely wide wire). The observed anisotropy is attributed to crystallographic anisotropy of the Fermi velocity and the resultant anisotropy of the electron mean free path in W, and underscores the critical role of crystallographic orientation in nanoscale metallic conduction. | - |
