The fabrication of the twist-bonded bicrystal is illustrated by the QuickTime movie to the left. As the angle between the two crystals changes, the spacing between the dislocations also changes. Large misorientation angles correspond to small dislocation spacings and vice versa. The table below illustrates the correlation between dislocation spacing and misorientation angle for a silicon bicrystal. ![]() At least in principle, this technique will allow for nanofabrication at the biological length scale. For example, to match the 10 nm spacing of the receptors on a human antibody, a twist angle of about 2 degrees would be necessary. |
