Triggering of a dislocation avalanche during the unloading stage following a previous one, for a 1.5 \(\upmu\)m Mo micropillar at 25\({}^{\circ }\)C. a The entire SS-curve, zoomed in (b) to show such event. This signature of thermally activated triggering was neither observed for Mo pillars with sizes \(L<\)1 \(\upmu\)m and/or T=\(200^{\circ }\)C, nor for Al pillars, whatever their sizes
