Light-Emitting Diodes, or LED's are devices that emit infrared or visible light when charged with an electric current. LED's are rapidly being adopted as an efficient and low energy solution in a broad range of applications from indicator lamps to general lighting. LED's are fabricated on compound semiconductor substrates such as GaAs and GaN. VEM is working with many of the largest suppliers of LED devices. We're helping them develop new materials and new solutions to their R&D and production challenges.

Our components include:

RF Wireless Communications

The rapid growth of smartphones has driven a demand for high speed communications devices. The explosive growth of this industry requires significant high quality materials to keep up with the constant new innovations. These materials must be of high purity and low resistivity to provide maximum performance. We supply ultra high purity gold Evaporation Materials in any shape or size you may need at fair prices. VEM is working with all of the major RF Wireless device manufacturers to find solutions to their next generation devices.
