Recent developments in frequency modulation atomic force microscopy enable simultaneous measurement of frequency shift and time-averaged tunneling current. Determination of the interaction force is facilitated using an analytical formula, valid for arbitrary oscillation amplitudes ͓Sader and Jarvis, Appl. Phys. Lett. 84, 1801 ͑2004͔͒. Here we present the complementary formula for evaluation of the instantaneous tunneling current from the time-averaged tunneling current. This simple and accuratedoi:10.1063/1.3464165 fatcat:ep2d6vplija43alpbtmqplppli
