This is explored in copper crystal pillars with sizes around 200nm prepared by focused ion beam. Pillar 1 is a single crystal while pillar 2 and pillar 3 contain one and three high angle boundaries, respectively. Low yield stress and large stress drops were observed in pillar 1, but small drops are present in pillar 2 and 3.  The existence of high angle boundaries in pillar 2 and 3 removes the large stress drops by preventing the escape of dislocations from the pillar and the presence of these boundaries increases the stress of crystals 2-3 times. The significant effect of grain boundaries in the crystals is analyzed by combining the observation of microstructure, crystal rotation and strength as a function of the plastic strain.
