Schematic structure of (110) device.
I-V characteristics of the fabricated device with and without illumination.
PL peak energy shift as a function of applied bias voltage measured at RT. The inset shows PL spectra at applied bias voltages of 0 V and –20.4 V, whose peak energies, respectively, correspond to 1.452 eV and 1.448 eV.
Time evolution of the degree of polarization measured utilizing polarization- and time-resolved PL measurements at applied bias voltages of 0 V, –14.8 V, and –20.4 V. are 4.0 ns, 1.1 ns, and 0.3 ns, respectively.
