This material requires E-beam evaporation with a compatible hearth liner; thermal evaporation requires feasibility inquiry. Deposition source hardware and process route must be matched to the material's melting point and film requirements.
- Evaporation Method Constraint: E-beam evaporation is the preferred method; thermal evaporation requires feasibility inquiry.
- Hardware Compatibility: Use an E-beam hearth with a compatible liner; a high-temperature crucible may be required for thermal evaporation.
- Material Thermal Properties: The melting point of 800°C and density of 6.1 g/cm³ influence evaporation rate and film uniformity.
- Process Matching Requirement: Evaporation source hardware and process route must be matched to material behavior and target film properties.
- Pre-Order Verification: Confirm deposition-source compatibility and required quantity before placing an order.
What are the limitations of using thermal evaporation for GaN compared to E-beam evaporation?
Thermal evaporation of GaN is not recommended as the primary method due to the material's high melting point of 800°C and potential for decomposition. The product specification indicates E-beam evaporation is preferred, while thermal feasibility requires a request for quotation (RFQ) and use of a high-temperature crucible with compatible liner. For reliable deposition, an E-beam hearth with a compatible liner, such as Al2O3, is advised.
Which crucible liner materials are compatible with GaN evaporation at 800°C?
The recommended crucible liner for GaN evaporation is Al2O3 (alumina), as listed in the hardware compatibility section. For high-temperature applications, a custom crucible can be requested via RFQ. The liner must withstand the 800°C melting point and the reactive nature of GaN vapor.
How does the 12 mm piece size affect GaN evaporation source loading and film uniformity?
The 12 mm piece size is designed to facilitate source loading and consistent evaporation in E-beam hearths. Larger pieces ensure uniform thermal contact and reduce the risk of spitting during deposition. Buyers should confirm their deposition source geometry to ensure the 12 mm pieces fit securely in the crucible liner.
Gallium Nitride (GaN) evaporation material in pieces, 99.95% purity, 12 mm size, suitable for E-beam evaporation with compatible liner. Available in 100g, 500g, 1kg packs. Melting point 800°C necessitates careful process control.
Positive
- High purity 99.95%: The 99.95% material specification supports consistent film stoichiometry and reduces contamination risk in sensitive thin-film deposition applications.
- Specified piece size 12 mm: Pieces sized at 12 mm facilitate loading into E-beam hearths and allow reproducible evaporation rates, aiding process stability.
Trade-offs
- Thermal decomposition risk at 800°C: GaN has a melting point of 800°C and may decompose under vacuum; E-beam evaporation is preferred, and thermal evaporation requires a high-temperature crucible by RFQ, increasing process complexity.
- Crucible and liner compatibility required: Evaporation hardware must include a compatible liner (e.g., Al2O3) and potentially a custom high-temperature crucible, adding infrastructure dependencies for lab deployment.
