Improved electrical mobilities from implanting InP at elevated temperatures

Abstract
InP has been implanted with silicon to investigate the effect of implantation temperature on the postannealed electrical mobility. A significant improvement, by a factor of ∼2, occurs on implanting at 200 °C rather than at room temperature. Dislocations found after the room‐temperature but not the 200 °C implants may account for the mobility differences.
