8.3 CNT Id-Time: CNT FET Id-Time Characteristic (A.01.20)
[Supported Analyzer]
B1500A, 4156B, 4156C
[Description]
This Algorithm evaluates the drain current with drain voltage for the gate condition change which is used as
the DNA or the antibody sensor.
The IV curves between drain and source is measured with the gate condition change which indicat amunt of
the DNA or the antibody on the gate surface as a sensor.
The Algorithm is applied the time dependent measurement.
