Ch/ChE 140 b - Spring 2006
Principles and Applications of Semiconductor Photoelectrochemistry

Catalog Description

Ch/ChE 140 ab. Principles and Applications of Semiconductor Photoelectrochemistry. 6 units (4-0-2); second, third terms. Prerequisite: APh/EE 9 or instructor's permission. The properties and photoelectrochemistry of semiconductors and semiconductor/liquid junction solar cells will be discussed. Topics include optical and electronic properties of semiconductors; electronic properties of semiconductor junctions with metals, liquids, and other semiconductors, in the dark and under illumination, with emphasis on semiconductor/liquid junctions in aqueous and nonaqueous media. Problems currently facing semiconductor/liquid junctions and practical applications of these systems will be highlighted.

Teaching Assistant: Craig Wiggenhorn, 040 B.I., x2711,

General Course Information

The course will consist of reading and discussing about five articles per week from the semiconductor literature. Some discussions will take place in class, and other discussions will be held via an online forum. There will also be at least one problem set and a final exam.

List of Articles

The majority of the articles we will be discussing are available online. The remainder will be distributed in class. Access to the articles is restricted to those within the Caltech network. If you are accessing the site from outside the Caltech network, you will be prompted for the username and password that was provided to you at the beginning of the course.

Discussion Forum

Access to the online discussion forum requires a brief registration process:

  1. Go to the discussion forum site.
  2. Click the "Register" link near the top of the page and the "I Agree" link near the bottom of the next page.
  3. Fill in your desired username, email address, and password, and click the "Submit" button.
  4. Click the "Log in" link near the top of the page, enter your username and password, and click the "Log in" button.


Grades in the course will be based on your participation in discussions and performance on problem sets and a final exam.
