8.6 CNT Id-Vg-Time: CNT FET Ig-Vg characteristics (A.01.20)
[Supported Analyzer]
B1500A, 4156B, 4156C
[Description]
Measures the Id-Vg characteristics of CNT FET repeatedly at a specified interval until specified time elapses.
This test is designed to use a gate electrode as a sensor and consider the adsorption of DNA and antibody to the
gate electrode as a change in Ids. Used for evaluation of a time change in characteristics.
[Device Under Test]
Carbon Nano Tube FET, 4 terminals

[Measurement Parameters]
Drain current Idrain
Time ACC_TIME
ACC_TIME is displayed after adding the sum of T1Step (or T2Step) and the actual measurement time.
ACC_TIME = AC T1Step (or T2Step) + Id-Vg measurement time
[User Function]
ACC_TIME: Elapsed time
