Mercury selenide (HgSe)

Description:

Mercury selenide (HgSe) is an inorganic compound characterized by its distinct properties and applications. It appears as a dark red to black solid and is known for its semiconducting behavior, making it valuable in various electronic applications, including infrared detectors and photovoltaic cells. HgSe has a high melting point and exhibits a crystalline structure, typically forming in the cubic or hexagonal system. The compound is insoluble in water but can dissolve in acids, which is important for its handling and processing. Due to the presence of mercury, HgSe is toxic, necessitating careful management to prevent exposure. Its bandgap energy allows it to absorb infrared radiation, which is exploited in optoelectronic devices. Additionally, mercury selenide can be synthesized through various methods, including chemical vapor deposition and solid-state reactions. Overall, HgSe is a significant material in the field of materials science and electronics, but its toxicity requires stringent safety measures during its use and disposal.

Controlled Product

CAS: 20601-83-6

Mercury selenide is a semiconductor that has been studied extensively due to its unique electronic properties. Mercury selenide is a group II-VI semiconductor with a bandgap of 0.5eV, which allows it to be used in photovoltaic cells and solar panels. It also has a high thermal expansion coefficient, which makes it an excellent material for use in the manufacture of lenses for infrared cameras. Mercury selenide can be prepared by reacting mercury with elemental selenium at high temperatures. The resulting compound is then heated in vacuum until the mercury evaporates, leaving behind the solid form of mercury selenide.
