8.2 CNT Gate Leak: CNT FET Ig-Vg characteristics (A.01.20)
[Supported Analyzer]
B1500A, 4155B, 4155C, 4156B, 4156C
[Description]
Measures the gate current vs gate voltage (Ig-Vg) characteristics of CNT FET.
Measures Ig before and after applying Vg by using the primary sweep SMU that forces the start and stop
voltages only, and extracts the Ig-Vg characteristics by altering the stop value repeatedly.
[Device Under Test]
Carbon Nano Tube FET capacitor, 2 terminals
Connect SMU to the back gate and side gate and make the source and drain open.
