Description of Research
Dr. Phillips' research has a dual aspect. The first is creating quantum based switches. A recent proposal for this involved a single-electron transistor (SET) as the heart of an OptoElectronic Integrated Circuit (OEIC). This OEIC design utilized a sensitive quantum-wire detector, the SET for electron amplification, and a quantum-dot laser for its low threshold current. Calculations showed significant photonic gain. The second research aspect deals with semiconductor process modeling. An "Ion Migration Model" for diffusion has been created and tested. This extended diffusion model incorporates electric field effects; it is based upon fundamental mechanisms of atomic motion in diffusion.
