Abstract
We present a nonswitching van der Pauw technique using two independent ac current sources and two lock-in amplifiers. This technique may be useful to measure the resistance of delicate samples that might be easily damaged by electric shocks induced from switching, and can be extended to measure the anisotropy of resistance.
