This video contains the explanation of students' muddiest points regarding concepts in an introductory materials science course. This video includes content regarding the differences between intrinsic and extrinsic semiconductors. Sub topics include electron-hole migration, mobility, band structure diagrams, and conductivity equations for both p-type and n-type extrinsic semiconductors as well as intrinsic semiconductors. This video is the second in a series of three.
