AUTOMATION OF A CURRENT-VOLTAGE CHARACTERIZATION SYSTEM STUDENTS ADVISORS PHILLIP BUTLER DR. DOUG HARPER
JEFFREY DEJARNETTE DR. SANJU GUPTA
OVERVIEW
• Develop a system that will allow a researcher to perform a current versus voltage characterization of a sample
• Use Labview to autonomously control and communicate with stand-alone instrument
• Acquire Current-Voltage data of various materials (films)
• Project Unique Attributes
• Instrument Control
• Third Party interfacing
OBJECTIVES
• Provide alternative selections such as
• 2 or 4 probe system
• Sourcing current or voltage
• Single run or sweep function
• Send commands as strings
• Export data as text (delimited) document or spreadsheet format to be further analyzed
• Provide documentation for future expansions
EQUIPMENT
• Keithley 2400 Sourcemeter
• PC with Labview
• Electrical probes

WHERE WE ARE NOW
• Communication established
• Source meter initialization strings and codes
• Shutdown procedure
• Documenting setup procedures and progress
WHAT IS NEXT?
• Translate and export data as .txt files (ASCII)
• User friendly commands
• Reset setup preferences
• Pause/Stop data collection
