Gallium nitride powder requires e-beam evaporation with a compatible liner such as Al2O3 to prevent contamination. The material's melting point of 800°C and 35 µm particle size dictate specific deposition parameters and source geometry.
- Evaporation Method: Use e-beam evaporation as the preferred method; thermal evaporation feasibility requires a request for quotation.
- Liner Compatibility: Load the GaN powder into an e-beam hearth fitted with a compatible liner, such as Al2O3, to avoid chemical reaction with the crucible.
- Particle Size Consideration: The 35 µm powder size is suitable for direct loading into an e-beam hearth without further grinding.
- Melting Point Constraint: The melting point of 800°C determines the power and rate settings for stable evaporation.
- Procurement Verification: Confirm deposition-source compatibility and hardware configuration before placing the order to ensure process match.
What is the melting point and density of the GaN evaporation material, and how do these properties influence the recommended evaporation method?
The melting point of the GaN evaporation material is 800°C and its density is 6.1 g/cm³. These properties make E-beam evaporation the preferred method, as thermal evaporation may require special feasibility inquiry (RFQ). The material's melting point and density are critical for matching deposition source parameters and achieving consistent film quality.
Which crucible or liner materials are compatible with E-beam evaporation of GaN powder?
For E-beam evaporation, the GaN powder is compatible with an E-beam hearth using a compatible liner. The product specification lists Al2O3 as a documented liner material. High-temperature crucibles are also available by request (RFQ) for thermal evaporation feasibility.
What is the particle size of the GaN powder, and why is it specified for vacuum deposition?
The GaN powder has a particle size of 35 µm. This fine powder form is specified to support consistent source loading and controlled evaporation in vacuum thin-film deposition. The defined particle size helps ensure uniform evaporation behavior and reproducibility in E-beam processes.
Gallium Nitride (GaN) evaporation material in powder form (35 µm, 99.95% purity) is specified for E-beam evaporation using an Al2O3 liner, with a melting point of 800°C and density of 6.1 g/cm³, requiring source geometry confirmation before ordering.
Positive
- High purity and defined particle size: 99.95% purity and 35 µm powder sizing provide consistent evaporation behavior and film stoichiometry for E-beam deposition.
- Hardware-matched E-beam compatibility: Supplied for use with E-beam hearth and Al2O3 liner, a standard configuration for high-temperature evaporation of compound materials.
Trade-offs
- Thermal evaporation requires RFQ: Thermal evaporation is not directly supported; feasibility must be requested via RFQ, adding lead time for alternative deposition routes.
- Pre-order geometry and hardware confirmation needed: Deposition source geometry, crucible type, and liner compatibility must be verified by the buyer before quotation to avoid process mismatch.
