摘要： A scanning tunnel spectroscope comprises a generator for applying a bias voltage (V.sub.T) of a sin wave between a sample and probe, an I-V converter for converting a tunnel current flowing when the probe is set close to the sample, to a tunnel current representing voltage singal (I.sub.T), a detector for detecting the absolute value of the voltage signal (I.sub.t), and a servo circuit for servo-controlling a distance between the sample and probe using the absolute value with the servo time constant set larger than five times the period of the bias voltage. The information concerning the unevenness of the sample is obtained based on an output of the servo control means. A unit is provided for effecting the analog operation to derive a differential conductance based on the tunnel current on the real time basis and measuring the unevenness data and differential conductance between the sample and probe kept constant.

摘要： A bias voltage U.sub.B including a sine-wave voltage U.sub.T sin.omega. .sub.o t and an off-set voltage U.sub.REG is applied to an electrode on a sample. A potential U.sub.1 of the electrode is represented by: U.sub.1 =U.sub.REG +U.sub.T sin.omega. .sub.o t. A voltage including the bias voltage U.sub.B and a voltage .DELTA.U is applied to an electrode on the sample. A probe is approached to the sample by several nm, and a tunnel current I.sub.T flows therebetween. And the probe scans the surface of the sample. During the scan, the position of the probe is servo-controlled in the z-direction, to make constant the average absolute value of the tunnel current. The servo voltage is recorded thereby obtaining an STM image. Given that the potential difference between the electrode and a surface portion facing the probe is U.sub.S (x), the average of U.sub.1 +U.sub.S (x) becomes zero when the average of the tunnel current I.sub.T is zero. Accordingly, =0, that is, U.sub.S (x)=-U.sub.REG. Thus, by recording-U.sub.REG the potential distribution U.sub.S (x) on the sample surface is determined. Spectroscopic data is obtained by an analog operation unit, on the basis of a differential conductance .differential.I.sub.T /.differential.U.sub.T calculated from the tunnel current signal I.sub.T and the bias voltage U.sub.T.

摘要： A scanning tunneling potentio-spectroscopic microscope, includes a conductive probe and a circuit for selectively applying one of first, second and third bias voltages to a sample. A tunnel current flowing between the probe and sample is detected, and a tunnel current signal is produced upon detection thereof. A servo circuit controls a distance between the probe and sample on the basis of the tunnel current signal by producing a servo signal as a feedback signal. A hold circuit switches the servo circuit between operating and non-operating states. Configuration data on a surface of the sample is obtained, on the basis of the servo signal, with the first bias voltage applied to the sample and with the servo circuit in the operating state. A first dependence of the tunnel current on the bias voltage is obtained, from the tunnel current signal and the second bias voltage, with the second bias voltage applied to the sample and with the servo circuit in the non-operating state. A second dependence of the tunnel current on the bias voltage is obtained from the tunnel current signal and the third bias voltage, with the third bias voltage applied to the sample and with the servo circuit in the non-operating state. Electron state data is obtained on the basis of the first dependence, and potential data is obtained on the basis of the first and second dependencies.

摘要： A barrier height measuring apparatus includes a conductive cantilever with a probe which is placed close to a specimen. The cantilever is elastically deformed by the interatomic force existing between the cantilever and specimen while the cantilever is oscillated. The displacement of the cantilever against the specimen is detected while the distance between the probe and the specimen is controlled to maintain the oscillation amplitude of the cantilever to a constant level. The apparatus includes a bias source for applying a voltage of a predetermined waveform between the specimen and the cantilever to cause a tunneling current to flow between them, and an arithmetic processor for calculating the barrier height of the surface of the specimen from the tunnel current and the displacement of the cantilever.
