Free Keithley Web-Based Seminar Teaches Optimum Methods and Techniques for Making Electrical Resistivity Measurements

November 15, 2010

CLEVELAND, Nov. 15, 2010 /PRNewswire/ – Keithley Instruments, Inc. (NYSE: KEI), a world leader in advanced electrical test instruments and systems, will broadcast a free, web-based seminar titled “How to Make Electrical Resistivity Measurements of Bulk Materials: Conductors, Insulators, and Semiconductors” on Thursday, November 18, 2010. During this one-hour presentation, participants will learn the fundamentals of making resistivity measurements on bulk materials, as well as the various resistivity methods and techniques used to achieve optimal results. The on-line event also features an interactive question and answer session. To register, visit www.keithley.com/events/semconfs/webseminars.

Electrical resistivity is a basic material property and is a very common electrical measurement. Specific resistivity measurement methods are used depending upon the type of material, whether conductor, insulator, or semiconductor. Some of the specific methods include making four-wire resistance measurements of metals, volume and surface resistivity measurements of insulators, and four-point collinear probe and van der Pauw measurement methods of semiconductor materials. In addition to discussing these methods, measurement techniques that pertain to the method are also detailed. Some of the many techniques and sources of error discussed include electrostatic interference and shielding, leakage current and guarding, thermoelectric EMFs and offset compensation, and others. Along with using the proper method and techniques, the appropriate instrumentation must also be used to make the desired measurements.

“How to Make Electrical Resistivity Measurements of Bulk Materials: Conductors, Insulators, and Semiconductors” is recommended for materials researchers, research labs, physicists, universities, and companies who need to test resistivity of their products (solar cells, plastics, paper, tires, semiconductors, etc.).

About the Presenter.

Mary Anne Tupta, a lead applications engineer at Keithley Instruments, Inc. in Cleveland, Ohio, will present the seminar. Mary Anne has a Masters of Science in Physics and a Bachelor of Science in Physics/Electronic Engineering from John Carroll University in Cleveland, Ohio. She has been an engineer at Keithley for more than 20 years.

Registration Information.

“How to Make Electrical Resistivity Measurements of Bulk Materials: Conductors, Insulators, and Semiconductors” will be broadcast on Thursday, November 18, 2010 at 15:00 CET (9:00 a.m. EST) for the European audience and at 2:00 p.m. EST for the North American audience. The event is free to the public, but participants must register in advance at www.keithley.com/events/semconfs/webseminars.
