Title: Ute Rabe: Innovator in Atomic Force Microscopy
Introduction
Ute Rabe is a prominent inventor based in Saarbrücken, Germany. She has made significant contributions to the field of atomic force microscopy (AFM) with a focus on innovative devices and methods. With a total of 5 patents, her work has advanced the understanding and application of semiconductor materials in microscopy.
Latest Patents
One of her latest patents is a device for oscillation excitation of an elastic bar fastened on one side in an atomic force microscope. This device utilizes a leaf spring made of semiconductor material that lacks piezoelectric properties. The free end of the spring is equipped with a tip that contacts the sample surface for examination. The invention features a Schottky contact formed by connecting the leaf spring to a metal layer, along with an electrical voltage source that generates an AC voltage in the vicinity of the Schottky contact.
Another notable patent involves a method for determining dopant concentration in a semiconductor sample. This method employs an atomic force microscope where the leaf-spring tip contacts the semiconductor sample, forming a Schottky barrier. An electric alternating potential is applied to excite the space charge region within the semiconductor, allowing for the detection of oscillations that help determine the dopant concentration.
