What has to be done for obtaining usable results in the presence of extremely sensitive tunneling current? Correct Answer Use of gas spring systems

The extreme sensitivity of the tunneling current can be controlled by proper vibration isolation or a rigid scanning tunneling microscope body to obtain useable results. The very first scanning tunneling microscope made use of magnetic levitation to keep the device free from vibrations. Nowadays, mechanical spring or gas spring systems are employed. Vibration damping mechanisms are also implemented at times.
