arrays developed by their team in 2002 have been widely commercialized for general solid-state lighting and automobile headlights. Under the support of DARPA-MTO’s SUVOS, CMUVT, DUVAP, and VIGIL programs, their research team has contributed to the early developments of III-nitride deep UV emitters and detectors and InGaN energy devices in the United States. These include the prediction and confirmation that Al-rich AlGaN deep UV emitters emit light in the transverse-magnetic (TM) mode, the demonstration of the first UV/blue photonic crystal LEDs (PC-LEDs), AlN deep UV avalanche detectors with an ultrahigh specific detectivity and that his team was one of the first to experimentally determine the Mg acceptor energy level in AlN and to demonstrate the conductivity control in Al-rich AlGaN.

, their research team has realized semiconductor thermal neutron detectors based on hexagonal boron nitride with a record high detection efficiency among solid-state detectors. As a side hobby work while in graduate school, Hongxing Jiang and

have also developed the first analytical formalism based on the Newtonian gravitational force to describe the orbit of a star moving into and out of a galaxy and predicated the phenomenon of mass precession. This effect has been used by astrophysicists to constrain the abundance of dark matter in the solar system and the Galactic Centre.
