Hg1−xCdxTe or mercury cadmium telluride (also cadmium mercury telluride, MCT, MerCad Telluride, MerCadTel, MerCaT or CMT) is a chemical compound of cadmium telluride (CdTe) and mercury telluride (HgTe) with a tunable bandgap spanning the shortwave infrared to the very long wave infrared regions. The amount of cadmium (Cd) in the alloy can be chosen so as to tune the optical absorption of the material to the desired infrared wavelength. CdTe is a semiconductor with a bandgap of approximately 1.5 electronvolts (eV) at room temperature. HgTe is a semimetal, which means that its bandgap energy is zero. Mixing these two substances allows one to obtain any bandgap between 0 and 1.5 eV.

  • Cádmio Mercúrio Telureto ou HgCdTe ( também chamado de Mercúrio Cádmio Telureto, MCT, MerCad Telureto, MerCadTel, MerCaT ou CMT) é uma liga ternária (ou trinária) de CdTe e HgTe de uma estreita blenda banda proibida direta de zinco II-VI com uma banda proibida sintonizável, que abrangendo as regiões das ondas curtas do infravermelho até as regiões de onda infravermelha longa (pt)
  • Le tellurure de mercure-cadmium (HgCdTe), souvent appelé « mercatel » (abréviation du nom anglophone mercury cadmium telluride) est un alliage de tellurure de mercure (HgTe) et de tellurure de cadmium (CdTe). Le premier étant un semi-métal (pas de gap) et le second un semi-conducteur binaire de gap 1,5 eV à température ambiante, le tellurure de mercure-cadmium est un semi-conducteur ternaire dont le gap varie entre 0 et 1,5 eV, en fonction de la proportion de mercure et de cadmium. C'est l'un des matériaux semi-conducteurs dont le gap peut être le plus petit, et il trouve ses applications dans le domaine de l'opto-électronique infrarouge (photodétecteur infra-rouge, détecteur infrarouge, cellule photovoltaïque), la variation du taux mercure/cadmium permettant d'ajuster le gap aux applicati (fr)
  • Il tellururo di cadmio e mercurio (chiamato anche MCT o CMT) è un composto chimico di tellururo di cadmio (CdTe) e tellururo di mercurio (HgTe) con una banda proibita regolabile che va dall'infrarosso a onde corte a regioni dell'infrarosso a onde molto lunghe. La quantità di cadmio nella lega può essere scelta in modo da adeguare l'assorbimento ottico del materiale alla lunghezza d'onda infrarossa desiderata. Il tellururo di cadmio è un semiconduttore con una banda proibita di circa 1,5 eV a temperatura ambiente. Il [tellururo di mercurio è un semimetallo, il che significa che la sua energia di banda proibita è zero. La miscelazione di queste due sostanze consente di ottenere qualsiasi banda proibita compresa tra 0 e 1,5 eV.Lavora nel (detto MIR, che per definizione è il campo infrarosso (it)
