AlGaN-based solar-blind UV heterojunction bipolar phototransistors: structural design, epitaxial growth, and optoelectric properties

“…[1][2][3] In the military field, one of the core applications of solarblind UV photodetectors is missile approaching warning. 4 As is well known, in modern warfare, missiles are mainly used to attack the strategic targets that determine the victory or defeat of a war and even the survival of a country. Thus, the accurate and effective warning of incoming missiles appears to be crucial.…”

“…6 (iii) The skin of the missile rigging and tank emits UV radiation by friction with the atmosphere during the reentry segment. 4 Both of the high temperature particle radiation and the chemical luminescence contain strong solar-blind UV components. 7,8 Therefore, the solar-blind UV radiation in the missile exhaust plume detected using the corresponding solar-blind UV photodetectors can realize the approaching alarm of incoming missiles with a very low false alarm rate, which ensures the security of important strategic targets in the environment of precise attack war.…”
