This material is a compound evaporation powder for vacuum thin-film deposition. It requires E-beam evaporation for optimal performance, with thermal evaporation available only by RFQ, and must use a compatible liner material from graphite, Al2O3, BN, or W/Mo/Ta boat.
- Evaporation Method Preference: E-beam evaporation is the preferred method for this material, while thermal evaporation requires a request for quotation.
- Source Liner Compatibility: The evaporation source must use a liner made of graphite, Al2O3, BN, or a W/Mo/Ta boat to handle the material.
- Melting Point Requirement: The material has a melting point of 2330°C, requiring a high-temperature evaporation source capable of reaching this temperature.
- E-beam Performance Rating: E-beam evaporation performance is rated as fair, indicating acceptable but not optimal results.
This procedure outlines the key steps for using Gadolinium Oxide powder as an evaporation material in vacuum thin-film deposition. The process relies on the material's specified melting point, source liner compatibility, and preferred evaporation method.
Required Equipment: E-beam hearth, Graphite liner, Al2O3 liner, W/Mo/Ta boat
- Select evaporation method
Select E-beam evaporation as the preferred deposition method for this material. - Choose source liner
Choose a source liner material from graphite, Al2O3, BN, or a W/Mo/Ta boat to ensure compatibility. - Set evaporation temperature
Set the evaporation source to achieve a temperature near the melting point of 2330°C.
What is the expected evaporation performance of 99.99% Gd2O3 powder in E-beam versus thermal evaporation?
E-beam evaporation is the preferred method for this Gd2O3 powder, with performance rated as Fair. Thermal evaporation is possible only by RFQ (request for quotation). The E-beam performance rating indicates acceptable results when using the recommended hearth liner or boat, while thermal evaporation would require custom evaluation due to the high melting point and powder form.
What deposition source hardware and liner materials are required for evaporating Gd2O3 powder?
For E-beam evaporation, use a graphite, Al2O3, or BN liner inside the E-beam hearth, or alternatively a tungsten, molybdenum, or tantalum boat. The powder form (325 mesh) necessitates careful loading into these liners or boats to ensure uniform evaporation and avoid contamination. The specified hardware is critical for achieving consistent thin-film deposition.
What melting point and density values must be considered for vacuum deposition of Gd2O3?
Gd2O3 has a melting point of 2330°C and a density of 7.41 g/cm³. Achieving the high melting point requires E-beam evaporation as the preferred method; thermal evaporation is only possible via RFQ and may not be straightforward. The density value is relevant for calculating film thickness and deposition rate parameters in the vacuum system.
Gadolinium Oxide (Gd2O3) evaporation material supplied as 99.99% pure 325 mesh powder provides defined particle size for consistent source loading in E-beam or thermal evaporation, but requires specific hearth liners or boats (graphite, Al2O3, BN, W, Mo, Ta) and exhibits only fair E-beam performance, necessitating careful process matching.
Positive
- High purity 99.99%: The 99.99% purity specification supports controlled stoichiometry and reduced contamination in vacuum-deposited thin films, enabling reproducible results in research-grade applications.
- Defined 325 mesh powder form: The 325 mesh particle size provides consistent powder flow and uniform loading into evaporation sources, facilitating predictable evaporation rates and film thickness uniformity.
Trade-offs
- Fair E-beam evaporation performance: The material is rated as 'Fair' for E-beam evaporation, indicating lower deposition efficiency or potential film quality issues compared to materials rated 'Good' or 'Excellent', requiring optimization of beam parameters or alternative methods.
- Specific liner or boat material required: The evaporation source must use graphite, Al2O3, BN, W, Mo, or Ta liners or boats; incompatible materials may cause contamination or equipment damage, adding infrastructure and cost constraints for the laboratory.
