Structural and optical characterization of InGaN nanoparticles synthesized at low temperature

Low-Temperature Solution-Processed Flexible Solar Cells Based on (In,Ga)N Nanocubes

“…The thickness of the InGaN film ranges from 500 to 600 nm. The high intensity peak at 2θ = 26° corresponds to the PET substrate, , whereas the peak at 2θ =31.25° indicates h-InGaN. , As the In content increases, the In x Ga (1– x ) N peaks are shifted from that of GaN toward that of InN. Note the c-InGaN peak at 2θ = 40.28° between InN (200) peak at 39.75° and GaN (220) peak at 40.42° with x = 0.1 .…”

“…The In content ( x ) in In x Ga (1– x ) N nanocubes was calculated from the XRD results using the Vegard’s law where d InGaN , d GaN , and d InN are interplanear distance parameters of InGaN, GaN and InN, respectively. The average crystallite size of the synthesized nanoparticles ( D P ) was calculated using Scherrer’s formula, see Table . where D P is the crystal size of nanoparticles, β is the full width at half-maximum (fwhm) of broadened peak, λ is the wavelength of incident X-ray = 0.15406 nm, and θ is the Bragg angle. The In x Ga (1– x ) N energy band is calculated from eq , where the results are listed in Table . where b (1.43 eV) is the bowing parameter, pertaining the nonlinear fit of band gap energies, x is the indium ratio calculated from eq .…”
