Rubidium is highly reactive with moisture and oxygen, requiring strict dry inert handling at all times. Storage must be in sealed ampoules under inert atmosphere to prevent oxidation and pyrophoric reactions.
- Storage Atmosphere: Store the sealed ampoule in an inert gas environment (argon or nitrogen) to prevent degradation.
- Moisture Sensitivity: Exposure to ambient air will cause rapid oxidation and potential ignition; always handle in a glovebox.
- Boat Compatibility: Use only tantalum, molybdenum, or tungsten boats for evaporation to avoid contamination or reaction.
- Temperature Constraint: The melting point of rubidium is 39°C; ensure evaporation source temperature control to avoid premature melting.
This procedure outlines the safe transfer and evaporation of rubidium from sealed ampoule to deposition chamber. All steps must be performed under strict dry inert conditions to prevent hazardous reactions.
Required Equipment: Inert atmosphere glovebox, Ta/Mo/W evaporation boat
- Confirm Requirements
Confirm deposition source geometry, required quantity, and certificate requirements before opening the sealed ampoule. - Transfer to Glovebox
Transfer the sealed ampoule to an inert atmosphere glovebox for all subsequent handling procedures. - Load Evaporation Boat
Open the ampoule inside the glovebox and load the rubidium into a pre-cleaned Ta/Mo/W boat. - Transfer to Chamber
Transfer the loaded boat to the evaporation chamber under continuous inert gas flow to prevent air exposure. - Evacuate and Evaporate
Evacuate the chamber to high vacuum and heat the boat to evaporate rubidium onto the substrate.
What purity grade is available for rubidium evaporation material and how does it affect deposition quality?
The rubidium evaporation material is specified at 99.9% purity (3N grade), enabling direct comparison between standard and higher-purity grades for thin-film applications requiring controlled impurity levels.
What evaporation source materials are compatible with rubidium deposition?
Rubidium can be evaporated from a sealed ampoule directly or from tantalum (Ta), molybdenum (Mo), or tungsten (W) boats under strict dry inert handling conditions. The low melting point of 39°C requires careful temperature control during thermal/resistive evaporation.
What handling conditions are required for rubidium evaporation material due to its reactivity?
Rubidium requires strict dry inert handling during all stages because of its high reactivity with air and moisture. The material is supplied in sealed ampoules and must be loaded into the evaporation source under inert atmosphere using thermal/resistive evaporation methods only.
Rubidium (Rb) evaporation material in sealed ampoule form with 99.9% purity, supplied in 100g, 500g, or 1kg packs. Required for thermal evaporation under strict inert atmosphere due to high reactivity and low melting point.
Positive
- High purity 99.9%: The 99.9% purity specification provides a consistent composition for repeatable thin-film deposition, reducing variability in film properties.
- Sealed ampoule packaging: Supplied in a sealed ampoule to protect the highly reactive alkali metal from atmospheric moisture and oxygen, preserving material integrity during storage and handling.
Trade-offs
- Strict inert handling required: Rubidium must be handled under strict dry inert conditions (e.g., glovebox) to prevent violent reaction with air or moisture, adding laboratory infrastructure and safety requirements.
- Low melting point constraint: With a melting point of 39°C, the material requires careful temperature control during evaporation to avoid premature melting or uneven deposition, especially in resistive thermal processes.
