Figure 3

The strain data is converted to true-strain and representative regions of constant strain-rate and power dissipation are isolated as shown in (a).

Here each segment is a period of steady state plastic deformation under an applied load of 10 μN. The strain-rate of each segment is indicated below the data. Potential stress dependent flow was examined by load-jump tests. A representative portion of strain data from a load jump test on a different nanowire specimen is shown in (b). In this example data 1.1 mW were dissipated in the nanowire and the force was increased in 2 μN increments from 2 μN to 8 μN.
