(a) SEM images and (b) extinction spectra of 7 nm thick Pt metal annealed by RTA. Annealing times were 0, 40, 80, and 150 s at fixed temperature , respectively.
Room-temperature PL spectra of reference sample (without Pt metal) and PNC-formed InGaN MQWs. Samples were annealed for 0, 40, 80, and 150 s. The inset shows the PL intensity ratio of 80 s annealed PNC-formed sample (d) to the uncoated reference sample (a).
Temporal and spectroscopic profiles of InGaN MQWs (a) without and (b) with PNC. PL decay profiles of (c) uncoated reference and (d) PNC-formed InGaN MQWs at several wavelengths. In (b) and (d), PNC was formed by 80 s annealing.
(a) PL decay time of InGaN MQWs without and with PNC formed by fabricated with 80 s annealing. (b) Purcell enhancement factor calculated by the ratio of PL decay time as a function of wavelength.
