The ZnO-based heterostructures are predicted to be promising candidates for optoelectronic
devices in the infrared and terahertz (THz) spectral domains owing to their intrinsic material
properties. Specifically, the large ZnO LO-phonon energy reduces the thermally activated LO-
phonon scattering, which is predicted to greatly improve the temperature performance of
THz quantum cascade lasers. However, to date, no experimental observation of
intersubband emission from ZnO optoelectronic devices has been reported. Here, we report …
