A newly developed high resolution hot stage and its application to materials characterization

Abstract

Abstract. 2014 This paper describes the newly developed specimen hot stage and its applications. The hot stage is designed for high resolution TEM image observation at high temperatures and EDX analysis at room temperature. A fine metal wire is employed as the heating element of the stage and battery is used as the heating power source. The hot stage is particularly useful for particle specimens.By using this novel stage, a HREM observation of Si at high temperatures (~1400 °C) has been carried out. A dynamical observation of the surface of a PbTiO3 particle during heating and its chemical analysis using EDX before and after heating are also carried out.

Phase diagrams of nanometer-sized particles in binary systems

“…This technique uses a unique side-entry TEM holder equipped with a double-source evaporator, which is an improved version of a hot holder designed by Kamino and Saka. 9 A schematic illustration of the holder used is shown in Figure 1. The essential part of the holder consists of three spiral-shaped tungsten fi laments.…”

Dynamic chemical mapping near a Si/SiO2 interface at elevated temperatures using plasmon‐loss images

“…The powders were thermally oxidized at 1373 K in air to cover the surface uniformly with an amorphous layer of SiO 2 with 300 nm thickness. The specimens were heated using a heating holder (Kamino & Saka, 1993), which made use of a fine tungsten wire with a diameter of 25 mm as a heating element. The powdered specimens were mounted directly on to the heating element and heated at 1400 K. The specimens were examined at an accelerating voltage of 200 kV in a Hitachi HF-2000 electron microscope equipped with a Gatan GIF-200 energy filter.…”

Conventional Transmission Electron Microscope Observation of Electric and Magnetic Fields

“…The specimen holder used in this experiment was the Kamino holder. The Kamino holder that was originally designed by Kamino and Saka (1993) as a heating holder has two electrodes where a heating element is usually fixed. One of the electrodes is connected to ground and the other electrode, through which the external voltage can be applied, is insulated from ground.…”
