Deuterium
Gas Factfile
Deuterium is also known as “heavy hydrogen” due to the added mass of the neutron.
It is used in a variety of applications, ranging from university and industrial research comparisons between the hydrogen and deuterium in deposited film analysis, to use as a rapid thermal anneal for certain semiconductor devices where deuterium’s higher bond energy is desired.
