How does the Z-ratio of 0.841 for indium affect the accuracy of film thickness monitoring during thermal evaporation?
The Z-ratio of 0.841 is required to calibrate quartz crystal microbalance (QCM) monitors for the acoustic impedance mismatch between indium and quartz. This value, listed in the technical specifications, ensures accurate film thickness measurement when using this 99.99% purity indium wire. Without correcting for the Z-ratio, thickness readings can deviate significantly from actual deposited mass.
What are the considerations for using indium wire with thermal evaporation sources made of tungsten, molybdenum, or tantalum?
The indium wire is compatible with W/Mo/Ta filament, basket, coil, or boat sources as specified in the product description. However, because indium has a low melting point of 157 °C, it will melt and wet the filament surface, so the source material should be chosen to minimize alloying at deposition temperatures. The 2.0 mm diameter wire is designed to fit standard source geometries, but users should confirm their specific source loading dimensions.
How does the low melting point of 157 °C influence the deposition process parameters for this indium wire?
Indium's melting point of 157 °C, stated in the technical specifications, requires careful power control to avoid rapid liquefaction or spitting during thermal evaporation. The material will fully melt before evaporating, so the source must be configured to hold molten indium. Additionally, the density of 7.3 g/cm³ and Z-ratio of 0.841 are necessary inputs for process modeling and rate monitoring.
This Indium wire evaporation material offers 99.99% purity and a 2.0 mm diameter wire form, suitable for thermal evaporation with W/Mo/Ta sources. Selection of pack size (100g to 1kg) and consideration of the low melting point are critical for application matching.
Positive
- High purity 99.99%: The 99.99% purity specification minimizes contamination in thin-film deposition, ensuring consistent film properties for research-grade applications.
- Multiple pack sizes available: Available in 100g, 500g, and 1kg packages allows scaling from small to medium batch runs without excess material waste.
Trade-offs
- Requires compatible evaporation source: The material is designed for thermal/resistive evaporation using W/Mo/Ta filaments, baskets, coils, or boats; buyers must confirm source geometry compatibility before ordering.
- Low melting point demands process control: With a melting point of 157°C, the material evaporates at low temperatures, requiring precise temperature regulation to avoid spitting or uneven film thickness.
