애플리케이션

Tungsten (W) wire can be used for a variety of applications such as:
  • fabrication of tungsten tips which can be used as field emitters, nanoprobes and scanning tunneling microscope (STM) probes.
  • increase of the band gap of amorphous silicon germanium alloy.
  • formation of tungsten fibers for potential usage in the lighting industry.
