In this laboratory exercise you will examine semiconductor devices such as signal diodes, light emitting diodes, Zener diodes, laser diodes, solar cells, MOSFETs, JFETs, or bipolar transistors. We will measure the electrical charateristics of the devices and also look at the temperature dependence of the electrical characteristics. From these measurements we will try to extract some semiconductor properties like the band gap or the doping concentrations. If possible, we will look at the devices in an electron microscope. The reports will be written using the FAIR Principles of data management. FAIR stands for Findability, Accessibility, Interoperability, and Reuse of digital assets. Your measurements will be described in a way so that someone else could reproduce them and you will make the raw data available for others to analyze.

There are online notes describing diode measurements with a sourcemeter. Below are descriptions of experiments done by students in this course. These descriptions can act like a template for your own report.
