Magnesium selenide properties

It also combines with a number of metals to form compounds called selenides. An example is magnesium selenide (MgSe). One of selenium s interesting properties is its reaction with oxygen. It burns in oxygen with a bright blue flame to form selenium dioxide (Se02). Selenium dioxide has a characteristic odor of rotten horseradish. 

The molar ratio of the III compound to the V compound is typically l/lO.t ] To obtain the desired semiconductor properties, dopants are added such as zinc (from diethyl zinc) or magnesium (from bis(cyclopentadienyl) magnesium) for p doping, and silicon (from silane) or selenium (from hydrogen selenide) for n doping. 

DLC coatings also have an opto-protective function, infrared window materials such as germanium, magnesium fluoride, cadmium telluride, zinc sulfide, and zinc selenide are rel h/ely soft and easily damaged and eroded by wind, rain, or particle impact. They have also poor resistance to corrosive environments. DLC coatings offer good protection with adequate optical properties. However, their narrow IR bandpass may limit the range of applications.
