Patents by Inventor Frederik Büchau

Frederik Büchau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11656244
    Abstract: The invention relates to a measuring device for a scanning probe microscope that includes a sample receptacle which is configured to receive a measurement sample to be examined, a measuring probe which is arranged on a probe holder and has a probe tip with which the measurement sample can be measured. A displacement device is configured to move the measuring probe and the sample receptacle relative to each other, in order to measure the measurement sample, such that the measuring probe, in order to measure the measurement sample, executes a raster movement relative to said measurement sample in at least one spatial direction. Movement measurement signals indicating a first movement component in a first spatial direction that disrupts the raster movement and a second movement component in a second spatial direction that disrupts the raster movement, which second spatial direction extends transversely to the first spatial direction.

  • Publication number: 20220244287
    Abstract: The invention relates to an arrangement having a measuring apparatus for a scanning probe microscope, comprising: a sample receptacle, which is designed to receive a measurement sample for an examination by scanning probe microscopy; a measuring probe, which is received on a probe holder; a relocating device, which has a drive and is designed to relocate the sample receptacle and the probe holder having the measuring probe relative to each another by means of the drive for the examination by scanning probe microscopy; and an active counterweight device having a counterweight and a drive device associated with the counterweight, the active counterweight device being designed to move the counterweight during the measuring operation by means of the drive device, counter to the movement of the probe holder having the measuring probe. The invention furthermore relates to a method for operating the arrangement.

  • Patent number: 11156632
    Abstract: A measuring device for a scanning probe microscope including a sample receptacle configured to receive a sample; a measuring probe which is arranged on a probe holder and has a probe tip; a displacement device which moves the measuring probe and the sample receptacle relative to each other; a control device which is connected to the displacement device and controls the relative movement between the measuring probe and the sample receptacle; and a sensor device which is configured to detect, movement measurement signals during an absolute measurement for a movement of the measuring probe and/or a movement of the sample receptacle. The movement measurement signals are relayed to the control device. The control device is configured to control the relative movement. The invention also provides a scanning probe microscope, as well as a method for examining a sample.
