STEP - PN Junctions

Module Objectives

  1. Introduce students to science and engineering career opportunities.
  2. Develop deeper understandings of science concepts through analysis of applications.
  3. Develop vocabulary needed to converse in the semiconductor and nanotechnology industries.
  4. Develop skills needed to explore high-tech concepts independently.

Major Understandings

  1. P-N junction diodes are created by doping silicon with donor and acceptor atoms.
  2. I-V characteristics of P-N junction diodes allow current to flow in one direction only.
  3. A MOS transistor can be thought of as two back-to-back P-N junction diodes.
  4. A transistor can be thought of as a current switch, controlled by a  gate.
