    摘要: Observable changes in electrical and optical characteristics of individual molecules adsorbed on a conductor or semi-conductor caused by electrical and/or optical excitation or de-excitation of electrons within such molecules can be used as signals which in turn can be used to carry information and such observable information carrying changes or signals can be switched, amplified, and modulated by varying optical as well as electrical inputs to such molecules. Molecular structural design alters functional behavior of the molecular/quantum devices. In an example, monomeric metallated phthalocyanine behaves as a fast (

    摘要: A balanced momentum probe holder in an apparatus for characterizing a sample surface has first and second members each having extensible and retractable distal ends. The distal ends extend or retract substantially simultaneously in response to a signal from a detector thus balancing the momentums of the first and second members and reducing the net momentum of the probe holder to essentially zero. Balancing the momentum of the probe holder reduces parasitic oscillations in the apparatus thus enhancing performance.

    摘要: A scanning transmission electron microscope for imaging a specimen includes an electron beam source to generate an electron beam. Beam optics are provided to converge the electron beam. A stage is provided to hold a specimen in the path of the electron beam. A beam scanner scans the electron beam across the specimen. A controller may define one or more scanning areas corresponding to locations of the specimen, and control one or more of the beam scanner and stage to selectively scan the electron beam in the scanning areas. A detector is provided to detect electrons transmitted through the specimen to generate an image. The controller may generate a sub-image for each of the scanning areas, and stitch together the sub-images for the scanning areas to generate a stitched-together image. The controller may also analyze the stitched-together image to determine information regarding the specimen.

    摘要: A transmission electron microscope includes an electron beam source to generate an electron beam. Beam optics are provided to converge the electron beam. A specimen holder is provided to hold a specimen in the path of the electron beam. A detector is used to detect the electron beam transmitted through the specimen. The transmission electron microscope may be adapted to generate two or more images that are substantially incoherently related to one another, store the images, and combine amplitude signals at corresponding pixels of the respective images to improve a signal-to-noise ratio. Alternatively or in addition, the transmission electron microscope may be adapted to operate the specimen holder to move the specimen in relation to the beam optics during exposure or between exposures to operate the transmission electron microscope in an incoherent mode.

    摘要: The present invention is a method for localized chemical vapor deposition (CVD) for localized growing for example for carbon nanotubes (CNT), nanowires, and oxidation using a heated tip or an array of heated tips to locally heat the area of interest. As the tips moved, material such as CNTs grows in the direction of movement. The Scanning Probe Growth (SPG) or nanoCVD technique has similarities to the CVD growth; however it allows for controlled synthesis and direction and eliminates the need for masks.

    摘要: An apparatus for observing a sample (1) with a TEM column and an optical high resolution scanning microscope (10). The sample position when observing the sample with the TEM column differs from the sample position when observing the sample with the optical microscope in that in the latter case the sample is tilted towards the light-optical microscope. By using an optical microscope of the scanning type, and preferably using monochromatic light, the lens elements (11) of the optical microscope facing the sample position can be sufficiently small to be positioned between the pole faces (8A, 8B) of the (magnetic) particle-optical objective lens (7). This is in contrast with the objective lens systems conventionally used in optical microscopes, which show a large diameter. Furthermore the optical microscope, or at least the parts (11) close to the sample, may be retractable so as to free space when imaging in TEM mode.

    摘要: Disclosed is a measuring apparatus for a physical phenomenon by photoexcitation, in particular a delay time modulated and time-resolved, scanning probe microscope apparatus providing an ultimate resolution both temporal and spatial. The apparatus comprises an ultrashort laser pulse generator (2); a delay time modulating circuit (6) which splits an ultrashort laser pulse (3) produced by the ultrashort laser pulse generator (2) into two and which also modulates a delay time td between the two ultrashort laser pulses (4 and 5) with a frequency (ω); a scanning probe microscope (17); and a lock-in detection unit (8) which performs lock-in detection with the delay time modulation frequency (ω) of a probe signal (11) from the scanning probe microscope (17). It can detect the delay time dependency of the probe signal (11) as its differential coefficient to the delay time, with no substantial influence from fluctuations in the intensity of ultrashort laser pulses (3) while preventing the probe apex (19) from thermal expansion and shrinkage by repeated irradiation with ultrashort laser pulses (3). A photoexcited physical phenomenon dependent on a delay time between ultrashort laser pulses can thus be measured at a temporal resolution in the order of femtoseconds and at a spatial resolution in the order of angstroms.
