Gallium Antimonide (GaSb) evaporation material is a compound semiconductor for thin-film deposition. The material must be processed under controlled conditions to avoid decomposition and match source hardware.
- Decomposition Risk: E-beam evaporation is permitted only after a decomposition review due to the material's tendency to degrade under direct electron bombardment.
- Crucible Compatibility: The material must be evaporated from quartz, alumina, or graphite crucibles, or a sealed-source configuration must be used.
- Evaporation Method Constraint: Thermal evaporation is the recommended method, while e-beam evaporation requires prior evaluation and is rated as fair.
- Process Matching: Evaporation source hardware and process parameters must be matched to the material's melting point and film requirements.
What is the e-beam evaporation performance for GaSb pieces and what precautions are required?
E-beam evaporation of GaSb pieces is rated Fair and must only be used after a decomposition review. Thermal evaporation is the recommended method and should be arranged via RFQ. The product specification lists a melting point of 710°C and density of 5.6 g/cm³, which influence the evaporation behavior. Buyers must confirm deposition-source compatibility before quotation.
Which crucible materials are compatible with GaSb evaporation material?
Compatible crucible materials for GaSb evaporation include Quartz, alumina, and graphite. The specification also lists W and Ta as sheet2 hardware. For e-beam setups, a sealed-source configuration may be used by RFQ. The manufacturer advises confirming crucible material against the deposition hardware to ensure compatibility.
What does the 99.9% purity specification indicate for GaSb evaporation material?
The 99.9% purity specification represents a standard research-grade grade. The product description notes that this allows comparison between standard, high-purity, and RFQ-controlled grades. For applications requiring higher purity or controlled composition, custom RFQ may be needed. The purity is listed as a key parameter for procurement matching.
Gallium Antimonide (GaSb) evaporation material supplied as 99.9% pure pieces in 1–3 mm size range for vacuum thin-film deposition. The material requires thermal evaporation (RFQ) or e-beam only after decomposition review, with fair e-beam performance, and must be used with quartz/alumina/graphite or sealed-source crucibles. Pack sizes from 25 g to 1 kg allow flexible procurement for laboratory-scale runs.
Positive
- Defined material identity and purity: Gallium Antimonide (GaSb) with 99.9% purity enables clear procurement matching and consistent deposition-process performance.
- Specified physical form and sizing: Pieces in 1–3 mm range facilitate source loading and evaporation review, supporting reproducible thin-film deposition.
Trade-offs
- Restricted evaporation method compatibility: Thermal evaporation requires RFQ; e-beam is permitted only after decomposition review and yields only fair performance, limiting process flexibility.
- Crucible and setup constraints: Evaporation source must use quartz/alumina/graphite or sealed-source crucible by RFQ, which may not be compatible with all existing deposition hardware.
