Deep-ultraviolet integrated photonic and optoelectronic devices: A prospect of the hybridization of group III–nitrides, III–oxides, and two-dimensional materials

“…All of these show promise in advancing the development of the new "new electronics" industry [71] . While resonant tunneling transport is essential for the operation of ultrafast electronic oscillators and quantum cascade lasers [72][73][74][75] , this quantum mechanical effect remained elusive in the family of group III-nitride semiconductors until very recently [76,77] . Encomendero et al have engineered high-current resonant tunneling transport in group III-nitride heterostructures, which is employed to generate microwave power [76] .…”
