Q. Why MCT?
A. HgCdTe is the preferred material for producing infrared detectors due to its widely adjustable direct band-gap possibilities as well as excellent electrical properties, high absorption coefficient and moderate thermal expansion.

Q. Why bulk MCT?
A. Not only is bulk MCT the most robust, proven technology for harsh environments, now it is available in higher quality and thinner wafers than ever before. And with bulk-grown HgCdTe there is no compromise in lattice-matching to different substrates.

Q. Why NZ?
A. NZ is secure, neutral place to do business with.  We are high tech, customer-service and niche-oriented and very easy to communicate with. What's more, we work while you sleep!

Q. Why Spitfire?
A. In addition to "Why NZ", our company is independent. Our only reason for existence is to serve you the customer. See we should talk to you and our values.

Q. What is a COT?
A. Certificate of Test (COT) is the document we use to present and certify the quality of each wafer.

Q. What is X?
A. X is a measure of the composition of the crystal (it is the CdTe fraction) which predicts the infrared cut-off wavelength for a given sensor temperature. Our free article '10 Ways you can increase Yield with Spitfire MCT' explains in more detail how to convert to cut-on wavelength etc. Contact us and we will send you this informative bulletin free.

Q. What are 'mobility' and 'carrier concentration'?
A. These are measures which determine device sensitivity and response time...Our free article '10 Ways you can increase Yield with Spitfire MCT' explains in more detail how this relates to typical applications etc. Contact us and we will send you this informative bulletin free.

Q. What is an MSDS?
A. Material Safety Data Sheet (MSDS) can be downloaded here for the MCT which we make.
