Volcano Series In-Situ Holders (Optics&Biasing&Double Tilt)

Product Features

Optical fiber and MEMS chip are used to construct an optical and biasing composite multi-field automatic control and feedback measurement system in the in-situ sample stage.Combined with EDS, EELS,SAED,HRTEM,STEM and other different modes, the key information such as microstructure evolution, phase transition,elemental valence state,microscopic stress and atomic structure and composition evolution at the surface/interface of the sample under vacuum environment can be monitored in real time and dynamically from the nano or even atomic level with the change of light field and temperature.

  • Ag2Te-based thermoelectric materials change as the voltage applied changes。


    HRTEM of Ag2Te-based thermoelectric materials at 0.4V voltage .



    Ag2te-based thermoelectric materials can realize the conversion between electric energy and heat energy through the movement of internal carriers,so thatIn the process of applying volta ge experiment,the temperature of the sample will rise with the increase of voltage.The results show that with the continuous  increase of voltage,the surface structure of the sample changes o bviously,and the grain changes from irregular block to strip or disappear. In addition through the process of lowering voltage,we found that the surface structure change process is reversible when the material increases or decreases the voltage, indicating that the material has excellent 

    thermoelectric performance and reusable performance.
