Claim Text:
1. A radio-frequency (RF) reflectometry scanning tunneling microscope suitable for observing a surface of an object, said RF reflectometry scanning tunneling microscope comprising: a probe adapted to be positioned relative to the surface of the object, and to interact with the object to form a tunneling resistor therebetween; an RF resonant circuit including a first directional coupler coupled electrically to a second end of said inductor of said RF resonant circuit, and configured to receive an RF signal, to output the RF signal thus received to the LCR resonant circuit, and to receive a reflected RF signal that results from reflection of the RF signal by the LCR resonant circuit; and an RF signal measuring device adapted to receive the reflected RF signal from the LCR resonant circuit via said first directional coupler, and operable to generate a scanning result associated with the surface of the object based on the reflected RF signal; and wherein said RF signal measuring device includes
