Experimental procedure for the fabrication of electrodes and evaluation of bismuth nano- and microwires. (a) Configuration for Hall measurements of a bismuth nanowire. (b) Procedure for the fabrication and evaluation of electrodes on a 521-nm-diameter bismuth nanowire. The two-wire resistance was measured before FIB processing, and the I-V relationship and two- and four-wire resistance were measured after FIB processing. (c) Procedure for the fabrication of electrodes for Hall measurements.
