Free Keithley Webinar Teaches Fundamentals of Hall Effect Measurements

(PresseBox) (Cleveland, Ohio, ) Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, will broadcast a free webinar on "Hall Effect Measurement Fundamentals" on Thursday, February 17, 2011. This one-hour presentation will introduce Hall effect measurements as they relate to semiconductor materials and device characterization. The on-line event also features an interactive Q&A session. To register, visit

Hall effect measurement systems are commonly used to determine semiconductor parameters such as carrier mobility and carrier concentration, Hall coefficient, and conductivity type. Topics to be covered in the webinar include:

- What are Hall effect measurements and who uses them?

- What industry trends are driving the need for Hall effect measurements?

- What are the methodologies for deriving Hall voltage, resistivity, and carrier mobility?

- What are the key considerations when selecting equipment for Hall effect measurements?

- What techniques will help ensure quality measurements?

This seminar is recommended for materials scientists and physicists studying the electrical properties of new materials used in nanotechnology applications, as well as engineers, materials scientists, and physicists developing materials for thin-film solar/photovoltaic applications, working with compound semiconductor materials, or studying the properties of carbon-based devices. Additionally, it is useful for all characterization lab managers and anyone new to semiconductor materials and testing.
