Title
(EN) MERCURY CHALCOIODIDES FOR ROOM TEMPERATURE RADIATION DETECTION
(FR) CHALCOIODURES DE MERCURE POUR DÉTECTION DE RAYONNEMENT À TEMPÉRATURE AMBIANTE
Abstract
(EN) Methods and devices for detecting incident radiation, such as incident X-rays or gamma-rays, are provided. The methods and devices use single-crystalline mercury chalcoiodide compounds having the formula Hg3Q2I2, where Q represents a chalcogen atom or a combination of chalcogen atoms, as photoelectric materials. Also provided are methods for growing single-crystals of the mercury chalcoiodide compounds using external organic chemical transport agents.
(FR) L'invention concerne des procédés et des dispositifs de détection d'un rayonnement incident, tel que des rayons X ou des rayons gamma incidents. Les procédés et dispositifs utilisent des composés de chalcoiodure de mercure monocristallin ayant la formule Hg3Q2l2, où Q représente un atome de chalcogène ou une combinaison d'atomes de chalcogène, en tant que matériaux photoélectriques. L'invention concerne également des procédés de croissance de monocristaux des composés de chalcoiodure de mercure à l'aide d'agents de transport de produits chimiques organiques externes.
