NANOSCALE SCANNING SENSORS

A sensing probe may be formed of a diamond material comprising one or more spin defects that are configured to emit fluorescent light and are located no more than 50 nm from a sensing surface of the sensing probe. The sensing probe may include an optical outcoupling structure formed by the diamond material and configured to optically guide the fluorescent light toward an output end of the optical outcoupling structure. An optical detector may detect the fluorescent light that is emitted from the spin defects and that exits through the output end of the optical outcoupling structure after being optically guided therethrough. A mounting system may hold the sensing probe and control a distance between the sensing surface of the sensing probe and a surface of a sample while permitting relative motion between the sensing surface and the sample surface.

Diamond probe hosting an atomic sized defect

A method of manufacturing, characterizing, mounting, and a system of a probe may include a pillar having a taper angle and at least one engineered defect. The taper angle may be formed using crystallographic- or etching-based techniques. The probe may be mounted to an AFM chip. Furthermore, an RF waveguide may be connected to the AFM chip for providing RF excitation.

MAGNETIC DISTRIBUTION DETECTION METHOD

A magnetic distribution detection method includes the steps of providing a magnetic sensor and a sample, selecting a multiple of measuring points on the sample, sensing the measuring points by the magnetic sensor, obtaining a multiple of sense data and a series of the heights of the magnetic sensor from each measuring point, using a signal decomposition algorithm to convert these sense data into data groups, and selecting one of the data groups as the magnetic distribution data of the sample.

METHOD FOR DETECTING MECHANICAL AND MAGNETIC FEATURES WITH NANOSCALE RESOLUTION

The method for detecting mechanical and magnetic features comprises the steps of: aiming a probe of the sensor at a sample; defining several detected points for detection on the sample; detecting one of points and comprising the steps of: approaching the probe to the detected point from a predetermined height; contacting the probe with the detected point and applying a predetermined force on the detected point; making the probe far away from the detected point until to the predetermined height; shifting the probe to the next point for detection and repeating the detection; collecting the data of each of the detected points while the probe rapidly approaches to the points from the predetermined height; using a signal decomposition algorithm to transform the collected data to a plurality of data groups; and choosing a part of the data groups to be as data of feature distributions of the sample.

A diamond probe is suitable to be attached to an Atomic Force Microscope and is created with a tip that incorporates a one or more Nitrogen Vacancy (NV) centers located near the end of the tip. The probe arm acts as an optical waveguide to propagate the emission from the NV center with high efficiency and a beveled end directs excitation light to the NV center and directs photoluminescence light emanating from the NV center into the probe arm. The light source (or a portion of the light source), a detector, as well as an RF antenna, if used, may be mounted to the probe arm. The probe with integrated components enable excitation of photoluminescence in the NV center as well as optically detected Electron Spin Resonance (ODMR) and temperature measurements, and may further serve as a light probe utilizing the physical effect of Stimulated Emission Depletion (STED).

The probe arm acts as an optical waveguide to propagate the emission from the NV center with high efficiency and a beveled end directs excitation light to the NV center and directs photoluminescence light emanating from the NV center into the probe arm. The probe tip is scanned over an area of a sample with an electric charge, such as a field effect transistor or flash memory. Optically Detected Spin Resonance (ODMR) is measured as the probe tip is scanned over the area of the sample, from which a characteristic of the area of the sample with the electric charge may be determined.

MULTIFUNCTIONAL NANOPROBES FOR SCANNING PROBE MICROSCOPY

A multi-functional scanning probe microscopy nanoprobe may include a cantilever, a tapered structure formed on a surface of the cantilever from a first material, and a nanopillar formed on an apex of the tapered structure from a second material. One of the first and second materials may exhibit ferromagnetism and the other may have greater electrical conductivity. A method of simultaneous multi-mode operation during scanning probe microscopy may include scanning a sample with the nanoprobe in contact with the sample to produce a current measurement indicative of an electric current flowing through the sample and a height measurement indicative of a topography of the sample and, thereafter, scanning the sample with the nanoprobe oscillating about a lift height derived from the height measurement to produce a deflection measurement (e.g. phase shift) indicative of a magnetic force between the sample and the nanoprobe.
