Description:
Germanium is a brittle, grey‐white, semi‐metallic element. It reacts quickly and does not occur naturally on Earth. Germanium is commercially extracted from zinc ores, certain coals, argyrodites and germanite. It is used as a semiconductor in transistors, solar cells and optical materials.
Purified evaporation materials are used in deposition processes. They ensure that the deposited layers meet defined thickness criteria. Stanford Advanced Materials (SAM) produces germanium evaporation materials with a purity of up to 99,999 %. Quality assurance processes are implemented to maintain product reliability.

Applications:
1. Infrared Optics: Used in manufacturing optical infrared components such as infrared windows, lenses and prisms for infrared sensors and thermal imaging devices.
2. Semiconductor Devices: Employed as substrates or dopants in semiconductor materials for the production of devices such as diodes, solar cells and laser diodes.
3. Optical Coatings: Applied in the production of optical layers used in lenses, mirrors and optical filters. These layers regulate light transmission, reflection and absorption.
4. Nanotechnology: Utilised in the production of nanostructured materials and nano‐components such as nanowires, nanoparticles and quantum dots.
5. Material Research: Used as test materials and reference standards in studies of semiconductor, optical and nanomaterial properties and applications.
Packaging:
Our evaporation materials are handled carefully to prevent damage during storage and transport. This procedure maintains the product in its original condition.
