| Outline of Final Research Achievements |
In this research, a microheater/thermometer-embedded mechanically-controllable break junction was developed for measuring thermoelectric properties of size-configurable bismuth nanowires. A free-standing bismuth nanowire was fabricated by coating it with a platinum layer for protecting from the oxidation upon dry-etching of a polyimide layer. The thus obtained bismuth wire was stretched and narrowed gradually from sub-micrometer to single-atom scales mechanically via the MCBJ mechanism. Concurrently measured wire conductance showed step-wise decrease in the conductance reflecting the atomic rearrangements taken place during the mechanical deformations.
