DOI: 10.1109/jstqe.2016.2608618
Abstract: In this paper, terahertz (THz) quantum well photodetectors (QWPs) with metal-grating couplers are presented for normal-incident operation. Both one-dimensional and two-dimensional grating samples were fabricated. The photocurrent spectra and the peak responsivity were characterized. The… read more here.

DOI: 10.1109/lpt.2018.2863368
Abstract: Mg x Zn 1-x O/ZnO quantum well (QW) photodetectors were fabricated by a radio-frequency magnetron sputtering system. The QW structure largely reduced the leakage current, from 2.6 × 10 -7 to 1.0 × 10 -9… read more here.
