Sbin on Doping and Four Point Probe

This 3-page lab guide, created by the Nanotechnology Applications and Career Knowledge Support (NACK) Center at Pennsylvania State University, is for a 2-day laboratory activity on the operation of four point probes. During the lab, students will "observe material modification through dopant diffusion and to demonstrate the operation of a four point probe for the measurement of sheet resistance." With guidance from the instructor, students will create their own silicon wafer sample, and then modify the sample through "the application of a spin on dopant and furnace diffusion." The lab guide includes background on the calculation of sheet resistance and four point probes, experiment instructions, and post-lab student questions.
