This process has a characteristic length scale which increases as the square root of time, and is important for applications like CVD. In addition to mobility and lifetime, a constant describing this process for charge carriers was measured in the Haynes-Shockley experiment. A property called MRT measures the average amount of a time a particle undergoes this process, and is analogous to the number of times a particle returns to its starting position while undergoing a (*) random walk. This process can be described by laws which related the Laplacian of the concentration with the time derivative of concentration, and the "flux" of this process with the negative divergence of concentration; those laws are named for Adolph Fick. For 10 points, identify this process in which particles move from a region of high concentration to low concentration.
