    摘要: A magnetic-field-observation device and method for measuring magnetic force near a magnetic material specimen's surface with high resolution and detecting the polarity of the magnetic pole of specimen's surface. The device including: a probe; excitation mechanism that excites it; scanning mechanism that relatively moves the probe and specimen; alternating magnetic field generation mechanism to make the probe periodically undergo magnetization reversal and apply thereto an alternating magnetic field having magnitude not making the specimen undergo magnetization reversal; and modulation measurement mechanism for measuring degree of periodical frequency modulation of the probe's oscillation caused by its apparent spring constant periodically changed by force of periodically changed intensity and applied to the probe by alternating force through magnetic interaction between magnetizations of the probe and specimen, by frequency demodulation or by measuring intensity of one sideband wave spectrum among spectrums generated by the frequency modulation. The method performed using the device.

    摘要: A scanning magnetic microscope (SMM) (20) includes a current source (27) for imposing an excitation current to a conductor-under-test (CUT) (70) and, if applicable, a reference current to a proximally located reference conductor (72). During accelerated testing, the SMM (20) corrects thermal drift of the CUT (70) via the reference conductor (72). A sensor (21) may be cooled by a heat sink (31) such as a pump (33) directing an airstream or a coldfinger (80). The sensor may switch from a contact to a non-contact mode of scanning the CUT (70). The SMM (20) and methods are useful for measuring electromigration in a CUT (70) as it occurs, for assembling the images into time lapsed representations such as a shape of the CUT (70), for measuring electromigration as a function of a cross sectional area of a wire under a dielectric material (DM) (78), for determining electrical parameters of the CUT (70), and for optimizing a thickness of a DM (78) over a CUT (70). The SMM (20) and methods are further useful for measuring morphological changes in a CUT (70) due to other stressing conditions, such as temperature, excitation current, physical stress(es), hostile environment, aging, semiconductor “burn-in”, or irradiation.

    摘要: A method for determining a nucleotide sequence of a nucleic acid is provided that includes contacting the nucleic acid with a series of labeled oligonucleotides for binding to the nucleic acid, wherein each labeled oligonucleotide includes a known nucleotide sequence and a molecular nanocode. The nanocode of an isolated labeled oligonucleotides that binds to the nucleic acid is then detected using SPM. Nanocodes of the present invention in certain aspects include detectable features beyond the arrangement of tags that encode information about the barcoded object, which assist in detecting the tags that encode information about the barcoded object. The detectable features include structures of a nanocode or associated with a nanocode, referred to herein as detectable feature tags, for error checking/error-correction, encryption, and data reduction/compression.

    摘要: Sub-diffraction limited magneto-optical microscopy, such as Kerr or Faraday effect microscopy, provide many advantages to fields of science and technology for measuring, or imaging, the magnetization structures and magnetization domains of materials. Disclosed is a method and system for performing sub-diffraction limited magneto-optic microscopy. The method includes positioning a microlens or microlens layer relative to a surface of a sample to image the surface of the sample, forming a photonic nanojet to probe the surface of the sample, and receiving light reflected by the surface of the sample or transmitted through the sample at an imaging sensor. The methods and associated systems and devices enable sub-diffraction limited imaging of magnetic domains at resolutions 2 to 8 times the classical diffraction limit.

    摘要: An elongate probe (50) for use in probe microscopy comprises a module (51) provided between a probe tip (53) and a driver (52). In use the driver (52) applies oscillations to the module (51) which are transmitted by the module to the tip (53). With the probe tip (53) positioned close to the surface of a sample, any phase variance in the oscillation of the tip with respect to the driving oscillation is representative of an interaction between the tip and the sample surface. The elongate arrangement of the probe (50) is particularly beneficial when used to probe samples which require a liquid environment.
