Doping to Create a Semiconductor: Changing conductive properties through diffusion
14 Jan 2020 | | Contributor(s):: Kaye Sheets, NNCI Nano
In the semiconductor industry scientists take advantage of diffusion to “dope” or introduce atoms into a silicon wafer to change its conductive properties. The lesson simulates the diffusion of a gas phase substance (ammonia) into a solid substrate (gelatin) and compares the...
