Cell Lab 4N5 (99.995%) Selenium (Se) Sputtering Target

High-Purity Selenium Target for Semiconductor and Photoconductive Coatings

General Description

Cell Lab 4N5 (99.995%) Selenium Sputtering Target is a precision-manufactured, high-purity target designed for thin film deposition in semiconductor, photovoltaic, and optoelectronic applications. Selenium is a non-metallic, gray material with a metallic lustre, valued for its excellent photoconductivity and photovoltaic properties.
It is commonly used for CdSe and CIGS thin-film solar cells, X-ray photoconductors, and antibacterial coatings on implants. Despite its relatively high vapour pressure, careful process control enables stable sputtering and uniform thin-film formation.

Key Features

  • Ultra-High Purity (99.995%) – Ensures clean, defect-free film deposition.

  • Photoconductive & Semiconductor Grade – Ideal for optical and photovoltaic applications.

  • Good Adhesion & Uniformity – Produces stable, high-quality thin films.

  • Versatile Form Factors – Discs, plates, rods, or custom shapes available.

  • Custom Engineering – Tailored sizes and purity levels for specific research needs.

FAQ

Q1: Is selenium suitable for standard DC sputtering?
Selenium’s high vapour pressure makes RF sputtering or low-temperature processes more suitable for stable results.

Q2: Can I order custom-dimension targets?
Yes. Cell Lab supports custom thickness, diameter, and purity to match specific deposition systems.

Q3: What are the handling precautions?
Store and process selenium in a dry, controlled environment; avoid overheating to prevent sublimation.

Q4: Is selenium compatible with copper or aluminium backing plates?
Yes, though due to its soft and reactive nature, indium bonding is recommended for optimal thermal transfer.
