A constant used in calculations of this process is equal to Boltzmann's constant times temperature divided by the fundamental charge all times the mobility according to a relation derived by Einstein.
The profile of this process is one way to separate Irvin's curves. One model of this process for multicomponent systems was created by Maxwell and modified by Stefan. Excess interstitials generated by ion implantation lead to a "transient enhanced" form of this process during annealing. A constant used in calculations of this process is equal to Boltzmann's constant times temperature divided by the fundamental charge all times the mobility according to a relation derived by Einstein. One type of this process occurs in systems smaller than the mean free path and is named for Knudsen. That aforementioned constant can be obtained from an Arrhenius-type law and has units of centimeters-squared per second; it is related to the flux of this phenomenon by Fick's first law. For 10 points, identify this transport process that occurs in the presence of sufficient thermal energy and a concentration gradient.
