Crystallographic planes
Crystallographic planes are denoted by Miller indices.
5b
Algorithm for Miller indices
1. Read off intercepts of plane with axes in
terms of a, b, c
2. Take reciprocals of intercepts
3. Reduce to smallest integer values
4. Enclose in parentheses, no commas.

In the cubic system, a plane and a
direction with the same indices are
orthogonal. E.g. [100] direction is
perpendicular to (100) plane.
Correspondingly, [123] direction is
perpendicular to (123) plane.

Indices of crystallographic plane can be found from cross product of indices of
any two non-parallel directions in this plane.
Crystallographic positions
Crystallographic position
is denoted by three
numbers, which are
coefficients of the
position vector, e.g. ½½½
for the red atom.
Here the 'new' atom is at a/2 + b/2 + c/2
Silicon crystal has so-called "diamond type lattice".
Each Si atom has 4 nearest neighbors.
Diamond lattice starts with a FCC lattice and then
adds four additional INTERNAL atoms at locations
r = a/4+b/4+c/4 away from each of the atoms. In
other words, diamond lattice is formed by two FCC
lattices sifted by the vector r.

A Darlington Pair consists of two transistors with the first BJT driving the base terminal of the second transistor as shown in Figure 1 below. A. Set up the primary sweep voltages for V1 the same as shown in the lecture notes (see the Darlington pair IV curve). B.

Note that all resistor values in Example 1 must be recalculated. Your solution for the base to ground and base to collector resistors may not be unique.arrow_forward
