Crucibles for Molecular Beam Epitaxy (MBE) applications is a cornerstone technique for fabricating advanced semiconductor structures, especially III–V materials used in optoelectronics, highfrequency devices, and quantum technologies. PBN crucibles are the preferred choice for MBE systems thanks to their exceptional purity, thermal stability, and long service life. Their excellent electrical resistance and controlled thermal conductivity make them ideal vessels for evaporating a wide range of highpurity source materials with consistency and reliability.
However, besides PBN, we also have high quality crucibles made of Mo, W, Nb,Ta, Alumina and others thermal—resistant materials for MBE applications
Engineered for demanding ultrahighvacuum environments, our MBE crucibles ensure stable evaporation rates, minimal contamination, and dependable performance throughout extended operation.
Product Features for HighPurity MBE Crucibles
- UltraHigh Purity Materials: Made from 99.9%–99.999% purity PBN, Mo, W, Nb, Ta,
Alumina, and other refractory materials to ensure contaminationfree epitaxial growth.
- Exceptional Thermal Resistance:
Stable under extreme temperatures required for MBE evaporation; each material offers unique hightemperature and chemicalresistance advantages.
- Precision Machining: Tight tolerances and smooth surfaces provide uniform
flux,stable evaporation rates, and repeatable growth conditions.
- Chemical Inertness: Resistant to reactions with common MBE source materials
(Ga, In, Al, As, P, Sb, Te, Se, oxides), preventing degradation and crosscontamination.
- UHV Compatibility: Designed for ultrahigh vacuum environments (down to
10⁻¹⁰ Torr) with low vapor pressure and excellent thermalcycling durability.
- System Compatibility: Available for major MBE platforms (Veeco/EPI, Riber,
DCA) and custom systems, including effusion cells, valved sources, and oxide MBE.
- Custom Designs: Offered in various shapes and configurations (cylindrical,
conical, stepped, baffled, etc.) tailored to specific materials and flux requirements.
- Reliable Quality: Manufactured with strict quality control and full material
traceability for consistent performance.
