Helium & liquid nitrogen stages for SEM
Gatan cooling stages for SEM, ideal for stabilising beam sensitive materials, such as polymers and geological samples, and studying low temperature phases and semiconductors/superconductors.
- Cryogenic gas cooling – Faster and allows stage movements
- Remote cryogen dewar – No vibration and more space in the SEM chamber
- Dovetail sample holders – Good heat transfer for low sample temperatures; airlock loadable
- Extended temperature range options for multiple applications
Higher CL Efficiency
Low temperatures enhance the efficiency of cathodoluminescence, reducing the likelihood of competing non-radiative recombination events. Signal intensity and spectroscopic discrimination are improved, for better understanding of optoelectronic properties. Helium cooling is useful for research into indirect band gap semiconductors.
Higher CL efficiency enables the use of lower injection conditions. This improves spatial resolution, with smaller spot sizes and low accelerating voltage.
