What surface roughness and film purity specifications does the 4-inch single-sided platinum-coated substrate provide?
The listed coating specification is Ra ≤ 1 nm surface roughness with film purity of at least 99.999%. The film stack is Ti 30 nm / Pt 100 nm, and the available coating processes are electron-beam evaporation and magnetron sputtering.
Which substrate materials can be used with the 4-inch platinum-coated substrate?
Silicon wafer, glass, quartz, and sapphire substrate types are listed for this 4-inch single-sided platinum-coated product. Substrate dimensions, specification, and thickness can be customized, and the substrate type must be confirmed before quotation.
What order parameters must be confirmed before purchasing this 4-inch platinum-coated substrate?
The 4-inch size, single-sided coating, Ti 30 nm / Pt 100 nm film stack, substrate type, substrate thickness, and coating process must be confirmed before quotation. Custom dimensions and specifications should be included in the request.
The 4-inch single-sided platinum-coated substrate (Ti 30 nm / Pt 100 nm) provides a high-purity (≥99.999%) and ultra-smooth (Ra ≤ 1 nm) platinum surface on a choice of silicon, glass, quartz, or sapphire substrates, balancing electrochemical performance with substrate-dependent thermal and optical compatibility.
Positive
- Ultra-smooth and high-purity platinum film: The Ra ≤ 1 nm roughness and ≥ 99.999% film purity ensure consistent electrical contact and minimal contamination, which is critical for sensitive electrochemical and surface-science applications.
- Multiple substrate and process options: Availability of silicon, glass, quartz, or sapphire substrates with customizable thickness, plus electron-beam evaporation or magnetron sputtering, allows users to match thermal expansion, optical transparency, or deposition conditions to their specific experimental setup.
Trade-offs
- Confirmation required before quotation: Substrate type, thickness, and coating process must be confirmed with the supplier before ordering, adding a pre-purchase coordination step that may delay procurement if specifications are not pre-determined.
- Single-sided coating limits symmetric use: The single-sided coating configuration restricts the platinum layer to one side, making this substrate unsuitable for applications requiring identical electrochemical or thermal properties on both faces without additional processing.
