Surfaces

Surfaces. Lecture 17. Determining Diffusion Coefficients. In practice, one would do experiments at a series of temperatures with a tracer, determine the profile, solve Fick’s second law at each T for D . Plotting ln D vs 1/T yields D o and E B .

Surfaces

Surfaces. Lecture 18. Diffusion Rates. Probability of atom making a jump to vacancy is where ℵ is number of attempts and E B is the activation or barrier energy. Combining, total diffusion rate will be product of probability. of a vacancy times probability of a jump:

Intersecting Lines

Intersecting Lines. To find where two lines meet we can use SIMULTANEOUS EQUATIONS. For this reason it is useful to write the equations in the form Ax + By = C. Consider the following examples…. Example 27. Triangle PQR has vertices P(-3,6) , Q(5,12) & R(5,2).

Intersecting and parallel lines. Intersecting lines are lines that cross each other.

Intersecting and parallel lines. Intersecting lines are lines that cross each other. Parallel lines are lines that never cross each other - they keep the same distance apart from each other - forever. Alternate angles Alternate angles form Z shape angles in the parallel lines.
