I-V curve tracing for transistors is easily accomplished with the SpikeSafe SMU. The SpikeSafe’s short pulsing capability allows the true I-V curve to be obtained without distortion caused by heating. The graphs below show the I-V characteristic for an N-Channel MOSFET taken with an external voltage source driving the gate. As you can see the plots, taken with a pulse width of 20us, closely match the manufacturer’s datasheet.
