Title
(DE) VERFAHREN ZUR MESSUNG DER KRAFTWECHSELWIRKUNG, WELCHE DURCH EINE PROBE HERVORGERUFEN WIRD
(EN) METHOD OF MEASUREMENT OF AN INTERACTION, WHICH IS CAUSED BY A SAMPLE
(FR) MÈTHODE DE MESURE D'UNE INTERATION, QUI EST CAUSÉE PAR UN'ÉCHANTILLON
Abstract
(DE)
Verfahren zur Messung der Kraftwechselwirkung, welche durch eine Probe hervorgerufen wird, wobei eine Spitze mit einer Biasspannung gegen die Probe beaufschlagt und in einem so geringen Abstand zu der Probe geführt wird, dass ein messbarer Strom zwischen der Spitze und der Probe fließt und ein Sensor und Signalwandler S gebildet und im Bereich der Kraftwechselwirkung eingesetzt wird, der den durch den Spitze-Probe-Kontakt fließenden Strom in Abhängigkeit von der Stärke der Kraftwechselwirkung verändert. Ein Rastertunnelmikroskop hierzu ist offenbart.

(EN)
The invention relates to a method for measuring the force interaction that is caused by a sample, wherein a bias voltage compared to the sample is applied to a tip and the tip is guided at a such a small distance to the sample that a measurable current flows between the tip and the sample and a sensor and signal converter S is formed and used in the area of the force interaction, which area changes the current flowing through the tip-sample contact according to the intensity of the force interaction. A scanning tunneling microscope therefor is disclosed.

(FR)
L'invention concerne un procédé de mesure de l'interaction de forces provoquée par une sonde, une pointe étant soumise à une tension de polarisation contre la sonde et étant guidée à une très faible distance de la sonde, de telle sorte qu'un courant mesurable circule entre la pointe et la sonde et qu'un capteur et convertisseur de signaux S, qui modifie le courant circulant par le contact pointe-sonde en fonction de l'intensité de l'interaction de forces, soit formé et utilisé dans la zone de l'interaction de forces. L'invention concerne également un microscope à effet tunnel associé.
