How to Measure High Resistances and Small Voltages/Currents for Emerging Materials and Devices

As materials-based semiconductor devices continue to shrink and operate at ever-lower signal levels, researchers are finding it more difficult to validate and qualify devices, especially emerging devices made with next-generation nanoscale materials. As part of this scaling evolution, each successive generation of devices must be characterized with reduced voltage, current, and power levels because ever-smaller devices operate at correspondingly lower signal levels.

This webinar will examine a new approach, which enables one to easily and accurately source and measure signals that would otherwise be swamped by electrical noise in some applications.

Lake Shore’s Jason Chonko, the presenter, will discuss:

• How to better perform high-resistance measurements
• New technologies for performing DC and lock-in measurements
• The pros and cons of DC reversal versus AC/lock-in methods
• The importance of input and output impedance in such measurements
• Minimizing the effects of parasitic capacitance in your measurement

By Attending This Webinar, You Will Learn: 

• Best practices for measuring high resistances and performing nanoscale device measurements, including low current measurements
• How to use reversal techniques and minimize settling time
• The importance of when to use shielding and guarding on fixturing and cabling
• How Lake Shore's unique new DC/AC SMU module with integrated lock-in provides a comprehensive suite of measurements for easier characterization
