1 monolayer (ML) thick InN quantum well (QW) with InGaN barrier grown by radio-frequency plasma assisted molecular beam epitaxy (rf-MBE) is proposed for a new active layer of blue-green light emitters. Compared with previously reported 1 ML thick InN/GaN QWs, extended emission wavelength up to pure green region (~530 nm) is expected for these QWs with InGaN barriers. It is found that for the InN/InGaN QW structure, in which the InGaN layer is used as a barrier instead of GaN, very thin InN well layers are basically formed in the same manner as the InN/GaN QWs. Bluish-green emission is observed in the QW light-emitting diode (LED) and no blue shift is observed in electroluminescence spectra from the LED for various current levels, indicating an enhancement in the quantum efficiency by inserting the ultrathin InN well leading to suppression of the quantum confined Stark effect. |
