Why is MCT so special?

HgCdTe is the preferred material for producing infrared detectors due to its adjustable direct band-gap, excellent electrical properties, high absorption coefficient and moderate thermal expansion. Different cut-on wavelengths (ranging from 2 to 25 micron) can be achieved by changing the composition ratio, X, in MCT's chemical formula Hg1-xCdxTe.

Manufacturers of IR detectors appreciate that with bulk-grown HgCdTe there is no compromise in lattice-matching to different substrates, nor response variation through thickness. That is why they come to the only independent supplier of MCT… Spitfire Semiconductors.
