What This Document Is
This document is a laboratory write-up for Physics 111 at the University of California, Berkeley, specifically focusing on semiconductor diodes as part of a Basic Semiconductor Circuits (BSC) series. It serves as a guide for a hands-on laboratory experiment designed to explore the fundamental characteristics and applications of diodes. This lab is the first in a sequence of three focusing on essential semiconductor components, building towards more complex circuit design.
Why This Document Matters
This resource is invaluable for students enrolled in Modern Physics and Advanced Electrical Laboratory (PHYSICS 111) at UC Berkeley. It’s particularly helpful *before* and *during* the lab session to understand the theoretical underpinnings and practical procedures involved in working with diodes. Students preparing to design and build circuits, or those needing a solid foundation in semiconductor behavior, will find this material essential. It’s designed to be used in conjunction with referenced textbooks and prior lab notes.
