Professors Strive to Meet Moore's Law

Moore's Law - which states that the number of transistors that can fit on an integrated circuit should double every two years, has long been the standard the semiconductor industry strives for.  Lately though, that goal has been getting harder and harder to meet.

According to Larry Sumney, president of the Semiconductor Research Corporation (SRC), the world's leading university-research consortium for semiconductors, "Transistors are already so small you can't see them.  Eventually we will reach the point where they won't work because there is only room to move one electron, which is not reliable. You will need a different way to move information."

NC State Professors Veena Misra and Ki Wook Kim are researching two such ways.  Dr. Misra and graduate student Steven Novak are working on domain wall logic, which uses the spin and charge of electrons for logic and memory operations, via magnetic fields.  Dr. Kim is researching alternative substrates such as graphene, which can conduct electricity up to 100 times faster than silicon.

Both Dr. Misra and Dr. Kim are funded by the SRC's latest round of grants, totaling $11.2 million across three dozen universities.  The Semiconductor Research Corp. is located in Durham, North Carolina.
