    摘要: A method and apparatus for measuring the physical properties of a micro region measures the two-dimensional distribution of stress/strain in real time at high resolution and sensitivity and with a high level of measuring position matching. A sample is scanned and irradiated with a finely focused electron beam (23, 26), and the displacement of position of a diffraction spot (32, 33) is measured by a two-dimensional position-sensitive electron detector (13). The displacement amount is outputted as a voltage value that is then converted into the magnitude of the stress/strain according to the principle of a nano diffraction method, and the magnitude is displayed in synchronism with a sample position signal.

    摘要: A method for large-angle convergent-beam diffraction comprises selecting a portion of the diffraction pattern formed by an objective lens, by the use of a diaphragm. Then, a portion of the electron micrograph which is formed by the electron beam passed through the diaphragm is detected, thus producing a signal. This enables a large-angle convergent-beam electron diffraction method that permits one to examine a specimen region which is much narrower than conventional.

    摘要: A camera for photographing Kossel lines caused by irradiating crystalline specimens with electron beams is disclosed. Previously such photographs were taken either by back reflection or transmission methods with the plane of the photographic plate perpendicular to the beam axis. This causes numerous disadvantages. In the present embodiment the photographs are taken in a plane parallel to the electron beam, and technique for interpreting the photographs so taken is fully explained.
