Electromigration
Surface electromigration refers to the directed motion of atoms (adatoms) at solid surfaces, grain boundaries and interfaces which is caused by an electric current in the bulk of the material. It is considered a key factor determining the reliability of integrated circuits.

Differential Forms in Electromagnetic Theory
The differential forms research group at BYU is investigating the use of the calculus of differential forms in teaching and research. Differential forms have been used to express Maxwell's laws since early in this century, but many of the advantages of forms as a tool for applied electromagnetics have only recently been discovered.
