Chapter 39: Quantum Structure of Atoms, Molecules, and Solids

Study Plan

As we learn about the quantum structure of materials, we will consider such questions as:

  • The nearly free electrons in a metal interact with the atoms in a lattice, and this restricts the permitted energies of the electrons. How do these restrictions arise? (Section 39.4, page 1334)
  • Impurities are intentionally added to a semiconductor to modify the conductivity. How does the presence of impurity atoms affect the conductivity? (Section 39.4, page 1334)
  • How are regions with different impurities combined to make useful devices? (Section 39.5, page 1340)

Organize

  1. Prepare for lecture by reading the assigned sections from Chapter 39 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.
  2. Take the checkup quiz and work the Checkup questions in your textbook to assess your understanding of basic concepts. Take note of any topics you need to review further.
  3. Review the Examples from your textbook. These progress from simple to complex, and provide concrete illustrations of the concepts discussed.

Learn

  1. Re-read Chapter 39 and review your lecture notes.
  2. Access the Online Concept Tutorials given for this chapter. Tutorials use animation and interactive exercises to help develop your understanding of fundamental topics.
