Abstract:
The superimposition of a periodic potential wave to the tip movement control or the bias supply of an STM, in which a microwave frequency comb is generated in its tunneling junction, may be used to reduce or eliminate artifacts or other noise generated from outside the tunneling junction.

Claim (Index 1):
A method to determine carrier concentration of a semiconductor sample, the method comprising:\n a. placing the semiconductor sample in a scanning tunneling microscope (\u201cSTM\u201d), the STM comprising: tip control electronics, a tip circuit with a preamplifier and a shielded STM tip, the shielded STM tip being in proximity with, but not in contact with, the semiconductor sample, forming a tunneling junction; b. placing a shielded probe in contact with the semiconductor sample in proximity to the STM tip, the shielded probe having functional connection with a bias supply and a microwave detector, forming a probe circuit, the probe circuit and tip circuit forming a system; c. applying a periodic potential wave to the tip control electronics d. irradiating the sample with a mode-locked ultrafast laser, generating a microwave frequency comb in the tunneling junction; e. measuring the microwave frequency comb's power at sidebands of a given harmonic of the microwave frequency comb with the microwave detector; f. determining the localized spreading resistance of the semiconductor sample at the tunneling junction from the measured power; g. using data from repeated measurements at different locations on the semiconductor sample to determine carrier concentration of the semiconductor sample.
