The Cryogenic Cooling Stage Series independently developed by Beijing Goldenscope Technology Co., Ltd. (model: GSC-MK series) is one of the distinctive peripheral accessories for electron microscopes. It broadens the range of samples that can be observed with a scanning electron microscope, making it possible to directly observe a variety of samples, including liquids, hydrated samples, temperature-sensitive materials, and electron beam-sensitive materials. The controlled low-temperature environment provides a foundation for studying the temperature-dependent physical properties of materials, such as the close relationship between the fluorescence properties of semiconductor materials and temperature.For example, the cathodoluminescence (CL) emission spectra of certain III-V group alloys require the use of ultra-low temperature cold stages with liquid nitrogen or even liquid helium, as these spectra cannot be effectively detected at conventional room temperatures.

The Cryogenic Cooling Stage  finds wide application in the analysis of materials, semiconductors, biological samples, and more. In the field of semiconductor optoelectronics, the cold stage helps improve the luminescence efficiency of optoelectronic materials at lower temperatures. Under the same incident electron beam excitation energy, detection in a low-temperature environment can achieve higher intensity CL emission and sharpen the system’s spectra, making it more effective for studying weak light signal emissions. An important application of low-temperature CL measurements is the analysis of numerous line spectra, which can be interpreted using basic atomic and quantum mechanics terms and correlated with corresponding theoretical models.
