Physics 5335 Lectures

Physics 5335 (Semiconductor Physics) Lectures (Power Point format) Note: Some files contain special Greek &/or math symbols. Unless you have the proper fonts installed on your system, these won't be interpreted correctly by your computer! Click Here to learn how to reduce the # of pages when printing a Power Point file!

No reproduction &/or use of them other than by students in this course is allowed! Downloading: Some files are large! If you have a dial-up connection, this may mean long download times. It might be more efficient to SAVE the file & open it later, rather than open it directly. It also might be more efficient to go to the ATLC (library basement), & use their direct connections. I've tested all files using both Internet Explorer & Netscape browsers, & all work well.
