Specialty Semiconductors

5N Plus is the leading supplier of cadmium telluride (CdTe) to the solar cell (photovoltaic) industry. Typically requiring 5N purity, cadmium telluride is a semiconductor that enables the efficient conversion of solar energy into electricity.

CdTe is also used to manufacture nuclear radiation detectors (X-ray and gamma ray) for medical use.

Cadmium zinc telluride (CZT) is used to manufacture radiation detectors (X-ray and gamma ray) that do not require cooling and that produce excellent resolution by directly converting radiation into an electric signal. Raw materials (cadmium, tellurium and zinc) of very high purity are required to manufacture this type of detector.

Zinc telluride (ZnTe) is a semiconductor compound used in optoelectronic applications, as well as in cadmium telluride (CdTe) based solar cells and terahertz radiation detectors.

5N Plus manufactures and customizes high purity, dislocation-free, electrically-uniform Germanium wafers to meet demanding space solar and land-based solar applications.

5N Plus manufactures and customizes class-leading, high-purity Indium Antimonide wafers that provide superior resistivity, uniformity and lowest defects through a unique, unmatched crystal-growth method.  The wafers are used in advanced thermal imaging solutions, focal planar arrays and high-precision magnetic and rotary resistivity sensors.

III-V Infra-red LEDs on GaAs wafers emit light at a customizable wavelength with high uniformity and high efficiency.

Leveraging our multi-juction technology we offer light receivers, which can convert monochromatic light from a laser or LED source into electricity at very high efficiencies beyond 60% and with high voltages without additional amplification or transformation.

GaAs power diodes with high break-through voltages of 1200 V and more and high ampacity for high efficiency electronic applications are available in different designs for corresponding currents.
