College Department of Physics and Engineering Research Experiences for Undergraduates Summer 2005 Project Summary |
| Project Title: | Measuring Drift Mobility of Scandium Nitride Using Haynes-Shockley Experiment |
| Student Name: | Matt E. Koepke |

Scandium Nitride (ScN) films have been grown on ITO covered quartz substrates by reactive dc-magnetron sputtering (in a pure nitrogen atmosphere) at room temperature for approximately four hours. Hole mobility was measured using an optically injected time-of-flight technique utilizing sandwich geometry and 800 ps pulses of 481 nm laser light. Minority mobility was found to be ~ 5.0 * 10 ? ³ cm²/V.s.
