STM head with precise preamplifier (3pA-0.7nA)

The use of this head makes it possible to work in the tunneling microscopy, tunneling spectroscopy modes, to carry out electrically induced surface modification. The head contains a precision preamplifier allowing operation at low currents. This preamplifier noise is under 1.5 peak amperes in the frequency range of 5.5 kHz.
