1) Within a cubic unit cell on which you have labeled the x, y and z-axes:
a) Sketch the (110) plane.
b) Sketch a direction from the <100> family that is also on the (110) plane. Label its direction indices.
c) Sketch a direction from the <110> family that is also on the (110) plane. Label its direction indices.
d) Sketch a direction
from the <111> family that is also on the (110) plane. Label
its direction indices.
2) Make scale drawings of each of the following segments of
directions in silicon (lattice constant is 0.543 nm), using circles
to represent each of the atoms whose centers are on the segment.
The radii of the circles should also be drawn to scale, so that any
nearest neighbor atoms touch (if there are any nearest neighbors in
that drawing). Place an atom at each end of each segment. Clearly
label the separation distance between the centers of each atom on
the line segment.
a) A segment 1.086 nm long in the [100] direction.
b) A segment 1.536 nm long in the [110] direction.
c) A segment 1.881 nm long in the [111] direction.
