Developing Techniques to Measure Single Molecule Conductance By: Tyler Turner and Timothy Mathews Advisor: William Hetherington Design Considerations, Complications, and Instrumentation HP Nano-press Blade Gap Amplifiers OPA657 From: https://www.circuitlab.com/ From: DEM-OPA-SO-1A User's Guide From: DEM-OPA-SO-1A User's Guide This is the model circuit used to look at tunneling. This circuit was used as a comparison. From: https://www.circuitlab.com/ Image on right is the I vs. V curve of a ramp through a MOSFET and on the left is the I vs. V curve of the same ramp through a capacitor. To the left is a graph of a sine wave applied across a capacitor. To the right is a graph of a sine wave applied across the gate of a MOSFET with the drain and source tied together.
