Indium Phosphide (InP) evaporation material must be handled with awareness of its decomposition risk under electron beam exposure. Storage and processing should follow the material's compatibility with quartz, alumina, or graphite crucibles and sealed-source setups.
- Decomposition Review Requirement: Electron beam evaporation of InP requires a prior decomposition review to assess material stability under the intended beam conditions.
- Crucible Compatibility: The evaporation source must use quartz, alumina, or graphite crucibles, or a sealed-source setup, to avoid chemical reaction or contamination.
- Process Matching: The deposition source hardware and process route must be aligned with the material's melting point and film requirements.
This guide outlines the essential steps for handling and evaporating Indium Phosphide (InP) pieces in a vacuum deposition system. Proper crucible selection and decomposition review are critical to avoid material degradation and achieve desired film quality.
Required Equipment: Crucible (quartz, alumina, or graphite), Sealed-source setup, Thermal evaporation system, Electron beam evaporation system
- Verify Material Specifications
Confirm the material model, purity, form, and size range against the required deposition specifications. - Select Crucible Type
Select the appropriate crucible type (quartz, alumina, graphite) or sealed-source setup based on the evaporation method. - Conduct Decomposition Review for E-Beam
For electron beam evaporation, conduct a decomposition review to assess material stability before proceeding. - Match Process Parameters
Match the deposition source hardware and process parameters to the material's melting point and film requirements.
Can Indium Phosphide (InP) evaporation material be used directly in e-beam deposition without additional review?
No. The product specification states that e-beam deposition is permitted only after decomposition review, while thermal evaporation is supported by RFQ. This is because InP can decompose under high-energy electron beams, potentially leading to phosphorus loss and film stoichiometry issues. Researchers must evaluate thermal stability and confirm the process before using e-beam.
What crucible and heating element materials are compatible with this Indium Phosphide evaporation material?
The evaporation source supports quartz, alumina, and graphite crucibles, with sealed-source setups available by RFQ. For heating elements, tungsten (W) and tantalum (Ta) are listed as compatible, with graphite (Gr) also noted. The choice depends on the evaporation method and thermal requirements; for example, alumina crucibles are suitable for high-temperature stability.
What documentation and procurement checks are needed before ordering Indium Phosphide (InP) evaporation material?
Before quotation, buyers must confirm model, purity, form, size range, pack size, and deposition-source compatibility. Documentation including certificate, safety data sheet, and shipment conditions can be reviewed to ensure compliance with laboratory use requirements. Available pack sizes are 25g, 100g, 500g, and 1kg, with minimum order quantity 25g.
Indium Phosphide (InP) evaporation material in 1-3 mm pieces at 99.9% purity is suitable for thermal evaporation but requires decomposition review prior to e-beam deposition. Available in 25g to 1kg pack sizes, with melting point 1,070°C and density 4.8 g/cm³.
Positive
- 99.9% Purity and Defined Form: The material is supplied as 99.9% pure Indium Phosphide in 1-3 mm pieces, enabling precise composition control and consistent source loading for vacuum thin-film deposition.
- Thermal Evaporation Compatibility: InP pieces are recommended for thermal evaporation (by RFQ) and can be used in quartz, alumina, or graphite crucibles, providing a defined process route for downstream film requirements.
Trade-offs
- E-Beam Deposition Requires Decomposition Review: E-beam evaporation is only permitted after a decomposition review due to potential dissociation of InP, necessitating additional process analysis before adoption.
- Source Hardware and Quantity Confirmation Required: Deposition-source compatibility, crucible material, and pack size must be confirmed before quotation, as the material behavior depends on specific hardware and process parameters.
