Changing Conductive Properties by Diffusion

Changing Conductive Properties by Diffusion

This lab, presented by the National Nanotechnology Infrastructure Network, covers the concept of semiconductor manufacturing. Students will learn how scientist "take advantage of diffusion to "dope" or introduce atoms into a silicon wafer to change its conductive properties." The lesson simulates this phenomenon by diffusing ammonia into gelatin. A Teacher Preparation Guide, Student Guides, and Next Generation Science Standards applicable to the lesson are included.
